Molecular Biology News and Research

RSS

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.

Scientists dissect how sperm cells of the fruit fly build their flagella

Sperm swim, lung cells sweep mucus away, and the cells in the female Fallopian tube move eggs from the ovary to the uterus. Underlying these phenomena are flagella - slender, hair-like structures extending from the surface of the cells, that bend, beat or wave rhythmically. In the latest issue of the journal Developmental Cell, scientists from the Instituto Gulbenkian de Ciência (IGC), in Portugal, have dissected how sperm cells of the fruit fly build their flagella.

Fluorescent molecules 'tag' DNA and monitor looping process

In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material in some types of cells.

Scientists discover how pten gene causes brain changes that lead to autism-like behavior

Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition.

Nematode worms help identify potential cancer targets

Through novel experiments involving small nematode worms, scientists from Wyoming have discovered several genes that may be potential targets for drug development in the ongoing war against cancer. Specifically, researchers hypothesize that inhibiting these genes could reverse certain key traits associated with cancer cells.

Pathologist identifies HPV DNA fragments in post-mortem samples after Gardasil vaccination

According to Norma Erickson, President of SaneVax Inc., testimony provided for a coroner's inquest into the death of Jasmine Renata in New Zealand by Dr. Sin Hang Lee, a pathologist on the medical staff at Connecticut's Milford Hospital, revealed the discovery of HPV DNA fragments in post-mortem samples 6 months after Gardasil vaccination.

Studies identify genetic mutations that play important roles in startle disease

Two studies published in the Journal of Biological Chemistry identify genetic mutations that play important roles in the condition commonly referred to as startle disease. Startle disease is characterized by an exaggerated response to noise and touch, which can interfere with breathing, cause catastrophic falls and even result in death.

Orc1 mutations may explain pathology in manifestations of Meier-Gorlin syndrome

Research published Aug. 1 by scientists at Cold Spring Harbor Laboratory (CSHL) links gene mutations found in some patients with Meier-Gorlin syndrome (MGS) with specific cellular dysfunctions that are thought to give rise to a particularly extreme version of dwarfism, small brain size, and other manifestations of abnormal growth which generally characterize that rare condition.

IL-10 may improve success rates of skin autografts

Scientists have found that the anti-inflammatory molecule, IL-10, may improve success rates of skin autografts (skin moved from one site of the body to another). This information provides a valuable drug target that may benefit burn and accident victims.
