Clues to aspirin's anti-cancer effects revealed.....................

In continuation of my update on aspirin....

One of the world's oldest medicines may hold the secret to a very contemporary problem: preventing cancer. Exactly why salicylate shows such potential as an anti-cancer treatment remains unclear, but a new study in mice offers clues.

Salicylate, found in willow bark, has been a key ingredient in medicine cabinets for thousands of years – ancient Egyptian manuscripts describe it as a treatment for inflammation. In a modified form – aspirin – it remains a successful anti-inflammatory and analgesic. Recently, though, research has revealed a puzzling side-effect of taking aspirin: the drug seems to lower a person's chances of developing some forms of cancer.

Aspirin is rapidly broken down inside the body into salicylate, so to investigate aspirin's unexpected side-effects Grahame Hardie at the University of Dundee, UK, applied salicylate to cultured human cells derived from the kidney. He found that the drug activated AMPK, an enzyme involved in cell growth and metabolism that has been found to play a role in cancer and diabetes.

"This is an ancient herbal remedy which has probably always been part of the human diet," says Hardie. "But despite that we're still finding out how it works."

Co-author Greg Steinberg of McMaster University in Hamilton, Ontario, Canada, then tested high doses of salicylate on various types of mice. He found that those engineered to lack AMPK did not experience the same metabolic effects from salicylate as seen in mice with AMPK.

Salicylate, in a form called salsalate, has also shown promise as a treatment for insulin-resistance and type 2 diabetes. Those effects, however, appear not to be governed by AMPK. When insulin-resistant mice lacking AMPK were given salicylate, they showed the same improvement in blood glucose levels as normal mice.

"That's what makes aspirin so scientifically and clinically interesting," says Chris Paraskeva at the University of Bristol, UK, who was not involved in the work. "It potentially works through a number of different pathways."

Berries, Tea May Cut Men’s Odds for Parkinson’s Disease..

In continuation of my update on Flavonoids...

Regularly consumption of food and drink rich in substances called flavonoids, such as berries, apples, tea and red wine, can lower a man’s risk of developing Parkinson’s disease by 40 percent, new research suggests.

  “For total flavonoids, the beneficial result was only in men. But, berries are protective in both men and women,” said the study’s lead author, Dr. Xiang Gao, a research scientist at the Harvard School of Public Health and an associate epidemiologist at Harvard Medical School and Brigham and Women’s Hospital in Boston.

“Berries could be a neuroprotective agent. People can include berries in their regular diet. There are no harmful effects from berry consumption, and they lower the risk of hypertension too,” Gao added.

For the study, the researchers reviewed nutrition and health data from almost 50,000 men enrolled in the Health Professional Follow-Up Study and more than 80,000 women participating in the Nurses’ Health Study.

The researchers looked at dietary intake of five major flavonoid sources: tea, berries, apples, orange juice and red wine.

Over 20 to 22 years of follow-up, 805 people developed Parkinson’s disease — 438 men and 367 women.

When researchers compared those who ate the most flavonoids with those who ate the least, they found that only men saw a statistically significant benefit, lowering their risk of Parkinson’s by 40 percent.

Gao said it wasn’t clear why only men benefited from the extra flavonoid intake, but he noted that other studies have also found differences between men and women. Gao said it’s not clear if there’s a biological mechanism causing these differences, or another factor.

But, when the researchers looked at the dietary compounds individually, it was clear that berries could benefit both men and women, lowering the risk of Parkinson’s disease by about 25 percent for those who had at least two servings of berries a week.

Gao said that anthocyanins protect the cells from oxidative damage and they also have an anti-inflammatory effect, which may be how berries help to reduce Parkinson’s risk.

The study findings should be interpreted cautiously because the participants were mostly white professionals, and the results might not apply to other ethnic groups. Also, recollections of dietary intake may be faulty, and it’s possible that other properties of fruits and vegetables might have influenced the results, the authors said.

But, he added, it’s important for people to realize that this research isn’t applicable to people who already have the disease.

He also said it will be important to confirm these findings in other studies and learn the mechanism of how berries and other flavonoids appear to offer some protection against Parkinson’s disease.

FDA Approves New Impotence Drug Stendra

The U.S. Food and Drug Administration on Friday announced that it had approved Stendra, a new medication for erectile dysfunction.

Stendra (avanafil, see the structure) joins Viagra, Cialis and Levitra, all from a class of drugs known as phosphodiesterase type 5. According to the FDA, fast-acting Stendra is designed to be taken 30 minutes before sexual activity and at the lowest effective dose.

Whether the new drug adds any value to the existing range of impotence medications is unclear, one expert said.

Dr. Bruce Kava, acting chairman of urology at the University of Miami School of Medicine, said that

"the only advantage Stendra may have is a more rapid onset of action over the other drugs. The question is whether there are any advantages to a more rapid onset."

He noted that many patients don't respond to one or another of these drugs. But there is no way right now of telling who will respond to which drug. "Sometimes it's hit or miss," he explained.

Men will have to try these drugs to find the one that best suits their lifestyle, Kava said. For example, for some men Cialis works best because its effects seem to last much longer than that of the other drugs, he said.

Bacteria beware: Researchers have a natural sidekick that may resolve the antibiotic-resistant bacteria dilemma

Mice infected with Escherichia coli (E. coli) or Staphylococcus aureus(S. aureus) bacteria were given molecules called specialized pro-resolving mediators (SPMs) along with antibiotics. SPMs are naturally found in our bodies, and are responsible for mediating anti-inflammatory responses and resolve inflammation. An anti-inflammatory response is the body's attempt to protect itself from infectious agents and initiate the healing process.

The researchers found that specific types of SPM molecules, called resolvins and protectins, were key in the anti-inflammatory response to limit tissue damage by stimulating the body's white blood cells to contain, kill and clear the bacteria.

Administered with antibiotics, resolvins and protectins heightened immune response by commanding white blood cells to attack and engulf the bacteria, thereby quickly reducing the amount of bacteria in the blood and tissues.

RvD5-a type of resolvin-in particular was also helpful in regulating fever caused by E.coli, as well as counter-regulating genes responsible for mounting excess inflammation associated with infections; hence, limiting the collateral damage to the body while fighting infection.

Serhan and colleagues are the first to demonstrate RvD5, as well as its actions against bacterial invasion. The BWH team, collaborating with Fredrik Bäckhed, PhD of the Sahlgrenska Center for Cardiovascular and Metabolic Research in Sweden, found that germ-free animals produce high levels of resolvins.

Eating more berries may reduce cognitive decline in the elderly: Blueberries and strawberries, which are high in flavonoids, appear to reduce cognitive decline in older adults according to a new study. The study results suggest that cognitive aging could be delayed by up to 2.5 years in elderly who consume greater amounts of the flavonoid-rich berries.

Mystery of Bacterial Growth and Resistance Resolved ?

In continuation of my update on the mechanism of bacterial resistance...

Scientists at The Scripps Research Institute have unraveled a complex chemical pathway that enables bacteria to form clusters called biofilms. Such improved understanding might eventually aid the development of new treatments targeting biofilms, which are involved in a wide variety of human infections and help bacteria resist antibiotics. 

Biofilm formation is a critical phenomenon that occurs when bacterial cells adhere to each other and to surfaces, at times as part of their growth stage and at other times to gird against attack. In such aggregations, cells on the outside of a biofilm might still be susceptible to natural or pharmaceutical antibiotics, but the interior cells are relatively protected. This can make them difficult to kill using conventional treatments.

Past research had also revealed that nitric oxide is involved in influencing bacterial biofilm formation. Nitric oxide in sufficient quantity is toxic to bacteria, so it's logical that nitric oxide would trigger bacteria to enter the safety huddle of a biofilm. But nobody knew precisely how. In the new study, the scientists set out to find what happens after the nitric oxide trigger is pulled. "The whole project was really a detective story in a way," said Plate.

To learn more, the researchers used a technique called phosphotransfer profiling. This involved activating the histidine kinase and then allowing them to react separately with about 20 potential targets. Those targets that the histidine kinase rapidly transferred phosphates to had to be part of the signaling pathway.

"It's a neat method that we used to get an answer that was in fact very surprising," said Plate. 

The experiments revealed that the histidine kinase phosphorylated three proteins called response regulators that work together to control biofilm formation for the project's primary study species, the bacterium Shewanella oneidensis, which is found in lake sediments.

Further work showed that each regulator plays a complementary role, making for an unusually complex system. One regulator activates gene expression, another controls the activity of an enzyme producing cyclic diguanosine monophosphate, an important bacterial messenger molecule that is critical in biofilm formation, and the third tunes the degree of activity of the second.

Since other bacterial species use the same chemical pathway uncovered in this study, the findings pave the way to further explore the potential for pharmaceutical application. As one example, researchers might be able to block biofilm formation with chemicals that interrupt the activity of one of the components of this nitric oxide cascade.

New drug to tackle body fat problems

Leptin regulates energy homeostasis, fertility, and the immune system, making it an important drug target. However, due to a complete lack of structural data for the obesity receptor (ObR), leptin's mechanism of receptor activation remains poorly understood. Researchers have crystallized the Fab fragment of a leptin-blocking monoclonal antibody (9F8), both in its uncomplexed state and bound to the leptin-binding domain (LBD) of human ObR. They describe the structure of the LBD-9F8 Fab complex and the conformational changes in 9F8 associated with LBD binding. A molecular model of the putative leptin-LBD complex reveals that 9F8 Fab blocks leptin binding through only a small (10%) overlap in their binding sites, and that leptin binding is likely to involve an induced fit mechanism. This crystal structure of the leptin-binding domain of the obesity receptor will facilitate the design of therapeutics to modulate leptin signaling.

Re: FDA Approves Votrient for Advanced Soft Tissue Sarcoma...

In continuation of my update on Pazopanib..


U.S. Food and Drug Administration, approved Votrient (pazopanib) to treat patients with advanced soft tissue sarcoma who have previously received chemotherapy. Soft tissue sarcoma is a cancer that begins in the muscle, fat, fibrous tissue, and other tissues.

Votrient is a pill that works by interfering with angiogenesis, the growth of new blood vessels needed for solid tumors to grow and survive.


A rare cancer with many subtypes, soft tissue sarcoma occurs in about 10,000 cases annually in the United States. More than 20 subtypes of sarcoma were included in the clinical trial leading to approval of Votrient. The drug is not approved for patients with adipocytic soft tissue sarcoma and gastrointestinal stromal tumors.

"Soft tissue sarcomas are a diverse group of tumors and the approval of Votrient for this general class of tumors is the first in decades," said Richard Pazdur, M.D., director of the Office of Hematology and Oncology Products in the FDA's Center for Drug Evaluation and Research. "Drug development for sarcomas has been especially challenging because of the limited number of patients and multiple subtypes of sarcomas."

The safety and effectiveness of Votrient was evaluated in a single clinical study in 369 patients with advanced soft tissue sarcoma who had received prior chemotherapy. Patients were randomly selected to receive Votrient or a placebo. The study was designed to measure the length of time a patient lived without the cancer progressing (progression-free survival). The disease did not progress for a median of 4.6 months for patients receiving Votrient, compared with 1.6 months for those receiving the placebo.

The most common side effects in Votrient-treated patients were fatigue, diarrhea, nausea, weight loss, high blood pressure, decreased appetite, vomiting, tumor and muscle pain, hair color changes, headache, a distorted sense of taste, shortness of breath, and skin discoloration.

Votrient carries a boxed warning alerting patients and health care professionals to the potential risk of liver damage (hepatotoxicity), which can be fatal. Patients should be monitored for liver function and treatment should be discontinued if liver function declines.

Gabapentin drug helps people to quit cannabis..

We know that, Gabapentin (see structure; brand names Fanatrex, Gabarone, Gralise, Neurontin, Nupentin) is a pharmaceutical drug, specifically a GABA analogue. It was originally developed for the treatment of epilepsy, and currently is also used to relieve neuropathic pain. 

Now Scientists at The Scripps Research Institute have found clinical evidence that the drug gabapentin, currently on the market to treat neuropathic pain and epilepsy, helps people to quit smoking marijuana (cannabis). Unlike traditional addiction treatments, gabapentin targets stress systems in the brain that are activated by drug withdrawal.

In a 12-week trial of 50 treatment-seeking cannabis users, those who took gabapentin used less cannabis, experienced fewer withdrawal symptoms such as sleeplessness, and scored higher on tests of attention, impulse-control, and other cognitive skills, compared to patients who received a placebo. If these results are confirmed by ongoing larger trials, gabapentin could become the first FDA-approved pharmaceutical treatment for cannabis dependence.

"A lot of other drugs have been tested for their ability to decrease cannabis use and withdrawal, but this is the first to show these key effects in a controlled treatment study," said Barbara J. Mason, the Pearson Family Chair and Co-Director of the Pearson Center for Alcoholism and Addiction Research at Scripps Research. "The other nice thing about gabapentin is that it is already widely prescribed, so its safety is less likely to be an issue."

Natural products isolated from marine mollusks and sponges can reverse multidrug resistance in cancer cells

Oceans are a treasure trove of naturally produced chemical compounds with impressive and varied biological activity. One class of these compounds, the lamellarins, has some members that are cytotoxic, while others are able to reverse multidrug resistance in certain cancer cells. These lamellarins (see below structure) act by inhibiting the so-called P-glycoprotein, which enhances transport of anticancer agents out of cancer cells, thus rendering the cells multidrug resistant.

Now researchers lead by Professor Rob Capon, have set out to determine the structures of a variety of lamellarins and correlate them to the activity of the compounds. As they report in Chemistry—An Asian Journal, the activity is not determined by the core structure of the compounds but rather depends on the exact nature of pendant groups adorning the periphery of the molecule. Those compounds in which many hydroxy (OH) groups had been replaced with methoxy (OCH₃) were able to reverse multidrug resistance in human colon cancer cells, while those featuring a large number of hydroxy groups showed higher cytotoxic activity.

Natural products such as the lamellarins are often valued for their cytotoxic properties for use as anticancer drugs. Capon, however, comments, "Our investigation reaffirms the view that non-cytotoxic natural products can exhibit valuable biological properties that allude to both an ecological advantage and a pharmacological potential....

Coffee's Unique Health Benefits........

In continuation of my update on coffee, 

 

• Coffee is the greatest source of antioxidants in the American diet.3,4 And the good news is that sound scientific studies have found that the common fears about excess coffee consumption are invalid, and higher intake means bigger benefits. 
• An impressive number of studies have shown a strong association between higher consumption of coffee and a significantly reduced risk of most chronic diseases, including diabetes, cardiovascular disease, cancer, Alzheimer's disease, and others.
• With over 1,000 phytochemicals, coffee's unparalleled antioxidant punch no doubt plays a role in its protection against disease. But a multitude of direct biological actions on the body are suspected, such as an improvement in intracellular signaling,95,96 which may help prevent cancer, diabetes and more.
• Drinking just one cup of coffee a day - caffeinated or decaffeinated - can decrease the risk of developing diabetes by 13%.24 But at 12 cups a day, the risk of getting diabetes is slashed by 67%.21
• Far from being a risky habit, coffee has now been shown to provide powerful protection against an epidemic of diabetes and a rising tide of other age-related diseases. It's an all-natural and inexpensive elixir - to go!

 While I wanted to compile all the benefits of coffee in one article, I found a detailed article and many interesting ones at  Life Extension Magazine.

Potential Method to Control Obesity: Red Wine, Fruit Compound Could Help Block Fat Cell Formation

A compound found in red wine, grapes and other fruits, and similar in structure to resveratrol, is able to block cellular processes that allow fat cells to develop, opening a door to a potential method to control obesity, according to a Purdue University study. 

While similar in structure to resveratrol -- the compound found in red wine, grapes and peanuts that is thought to combat cancer, heart disease and neurodegenerative diseases -- piceatannol might be an important weapon against obesity. Resveratrol is converted to piceatannol in humans after consumption.

"Piceatannol (see structure) actually alters the timing of gene expressions, gene functions and insulin action during adipogenesis, the process in which early stage fat cells become mature fat cells," Kim said. "In the presence of piceatannol, you can see delay or complete inhibition of adipogenesis."

Use of common pesticide, imidacloprid, linked to bee colony collapse

We know that, Imidacloprid is a systemic insecticide which acts as an insect neurotoxin and belongs to a class of chemicals called the neonicotinoids which act on the central nervous system of insects with much lower toxicity to mammals. The chemical works by interfering with the transmission of stimuli in the insect nervous system. Specifically, it causes a blockage in a type of neuronal pathway (nicotinergic) that is abundant in insects and not in warm-blooded animals (making the chemical selectively toxic to insects and not warm-blooded animals). This blockage leads to the accumulation of acetylcholine, an important insect neurotransmitter, resulting in the insect's paralysis, and eventually death. It is effective on contact and via stomach action

Use of common pesticide, imidacloprid, linked to bee colony collapse: The likely culprit in sharp worldwide declines in honeybee colonies since 2006 is imidacloprid, one of the most widely used pesticides, according to a new study.

Immunotherapy and Chemotherapy Regimen May Prolong Survival in Advanced Cancers

In continuation of my update on interleukin and retinoic acid

Cancer patients who receive a combination of low-dose interleukin-2 and retinoic acid after conventional therapy seem to live longer than those who don't get the combination. 

Retinoic acid is derived from vitamin A. Interleukin-2, a compound that fortifies the immune system, is approved at high doses to treat "metastatic" melanoma and kidney cancer. Metastatic means that a cancer has spread.

The study showed that "these biological compounds may work at low doses. Bigger doses are not always better," said lead author Dr. Francesco Recchia, director of the oncology department at Civilian Hospital in Avezzano, Italy.

Recchia stumbled upon the possibility of using low-dose interleukin-2 (IL-2) when he switched a patient with metastatic melanoma who didn't tolerate high doses to a lower dose, and the patient had an extended response to the therapy.

This study involved 500 patients who had already responded well to chemotherapy. They had a variety of cancers, including ovarian, lung, colon, stomach, kidney, melanoma, breast and pancreatic.
