Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Galangin mediates apoptosis of hepatocellular carcinoma cells through mitochondrial pathway: Study

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide, particularly in China. However, HCC remains one of the more difficult cancers to treat. It is important to screen for new anti-cancer drugs. A number of dietary compounds possess anti-cancer properties. These dietary compounds may modify the activity of specific targets that control cell proliferation and apoptosis. Galangin could inhibit the methoxyresorufin O-demethylase activity of CYP1A2, CYP1A1 and P-form phenolsulfotransferase.

AMP conducts survey on Genetic Test Registry

Today, the Association for Molecular Pathology (AMP) submitted written comments in response to the Request for Information made by the National Institutes of Health (NIH) for its Genetic Test Registry (GTR). AMP conducted a survey of its membership to formulate a comprehensive response to the RFI. "With the vast majority of respondents working in a clinical laboratory setting, AMP is able to inform the NIH on the general reaction to the GTR, including insight to the community's concerns and guidance to ensure the GTR is a valued resource," said Dr. Karen Mann, President of AMP.

Down the silk road of the future

The Science paper notes that the development of silk hydrogels, films, fibers and sponges is making possible advances in photonics and optics, nanotechnology, electronics, adhesives and microfluidics, as well as engineering of bone and ligaments. Because silk fiber formation does not rely on complex or toxic chemistries, such materials are biologically and environmentally friendly, even able to integrate with living systems.

Genetics research team discovers new recurrent translocations

A genetics research team based at The Children's Hospital of Philadelphia continues to discover recurrent translocations—places in which two chromosomes exchange pieces of themselves. As many as 1 in 600 persons carry balanced chromosome translocations, which involve no loss or gain of DNA. Most such people appear healthy, but may have a child with abnormal chromosome composition and disabilities resulting from disrupted, extra or missing copies of genes.

New findings on snake venom toxin hold promise for developing heart disease, cancer therapies

Researchers seeking to learn more about stroke by studying how the body responds to toxins in snake venom are this week releasing new findings that they hope will aid in the development of therapies for heart disease and, surprisingly, cancer. The Japanese team is reporting in a Journal of Biological Chemistry "Paper of the Week" that they are optimistic that inhibiting a protein found on the surface of blood cells known as platelets may combat both irregular blood clotting and the spread of certain cancers throughout the body.

Life Technologies second-quarter Non-GAAP revenue increases 8% to $906 million

Life Technologies Corporation today announced results for its second quarter ending June 30, 2010. Non-GAAP revenue for the second quarter was $906 million, an increase of 8 percent over the $839 million reported for the second quarter of 2009. Excluding the impact of currency and prior acquisitions and divestitures, organic revenue for the quarter grew 6 percent over the same period in the previous year.

Tel Aviv University discovers molecular power behind memory

Neuroscientists have long wondered how individual connections between brain cells remain diverse and "fit" enough for storing new memories. Reported in the prestigious science journal Neuron, a new study led by Dr. Inna Slutsky of the Sackler School of Medicine at Tel Aviv University describes what makes some memories stick.

Morphine blocks new blood vessel and tumor growth: Study

Current research suggests that taking morphine can block new blood vessel and tumor growth. The related report by Koodie et al, "Morphine suppresses tumor angiogenesis through a HIF1α/p38MAPK pathway," appears in the August 2010 issue of the American Journal of Pathology.

New study reveals potential role of TGF-β1 in kidney disease

Fibrosis in the kidney is one of the key causes of progressive renal failure. High levels of the inflammatory molecule TGF-β1 in the kidney tubules due to tissue damage can cause fibrosis as well as nephron degeneration, resulting in loss of kidney function. To clarify the mechanisms regulating TGF-β1-mediated renal fibrosis, Koesters et al expressed high levels of TGF-β1 in renal tubules of mice. Nephron degeneration in this system was mediated by decomposition of the tubular cells. These data suggest that TGF-β1 may play a novel role in cell death of renal cells, thus contributing to renal fibrosis.
