Cell senescence does not stop tumor growth
Since cancer cells grow indefinitely, it is commonly believed that senescence could act as a barrier against tumor growth and potentially be used as a way to treat cancer. A collaboration between a cancer biologist from the ...

Genetics of melanoma chemoresistance
Malignant melanoma is a highly aggressive and notoriously chemoresistant form of cancer. In a new paper, Ohanna et al. reveal that anti-melanoma drugs may, paradoxically, induce a senescence-associated secretory profile ("secretome") ...

Scientists now know why some cancers become malignant and others don't
Cancer cells reproduce by dividing in two, but a molecule known as PML limits how many times this can happen, according to researchers lead by Dr. Gerardo Ferbeyre of the University of Montreal's Department of Biochemistry. ...

Control of cancer cell pathways key to halting disease spread, study shows
Oncogenes are like friends who've gone off the deep end. Normally steady, reliable members of the cellular workforce, these genes become very bad influences when mutated or expressed at high levels -- urging a cell to divide ...

Scientists discover how a tumor suppressor induces senescence and staves off cancer
A frequently mutated gene in human cancers is the reitnoblastoma (RB) gene, which controls a potent tumor suppression pathway. Mutations in the gene disable the vast and intricate RB pathway in virtually all tumor cells, ...
