Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

Microtubule stability linked to increased sensitivity to paclitaxel

SCIENTISTS have discovered how blocking key cell signalling proteins could help boost the success rate of the tumour-shrinking drug paclitaxel, according to a study published in the journal Cancer Research today.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

Elevating free radical levels suppresses appetite in obese mice

Obesity is growing at alarming rates worldwide, and the biggest culprit is overeating. In a study of brain circuits that control hunger and satiety, Yale School of Medicine researchers have found that molecular mechanisms controlling free radicals-molecules tied to aging and tissue damage-are at the heart of increased appetite in diet-induced obesity.

Scientists define specific protein complex that allows cells to remove damaged mitochondria

In a joint research effort with researchers at St. Jude Children's Research Hospital, and with help from scientists at The University of Pennsylvania, The University of Minnesota, and the National Institutes of Health, investigators from the Florida campus of The Scripps Research Institute have defined a specific protein complex that allows cells to rid themselves of damaged mitochondria, which are the energy producing machines of the cell.

Combination molecules with BRAF inhibitors may help overcome drug resistance in melanoma patients

About 50 to 60 percent of patients with melanoma have a mutation in the BRAF gene that drives the growth of their cancer. Most of these patients respond well to two novel agents being studied in clinical trials that inhibit the gene, with remarkable responses that are, unfortunately, almost always limited in duration.
