A new mechanism of regulating RNA degradation

...many of the tools cells use to regulate genes work after transcription, by moderating the activity and the life span of the RNA itself. One major pathway for such post-transcriptional regulation is called nonsense-mediated decay (NMD). Originally NMD was thought to destroy incorrectly transcribed or other...

Source of molecular triggers in cutaneous T cell lymphoma identified

...le of LC." The study also showed that CTCL cells, after stimulation by LC, become functioning regulatory T (Treg) cells that suppress the immune responses of normal T cells to microbial agents. This may explain the susceptibility of patients with extensive CTCL to opportunistic infections. "Through under...

If they stick to the sides then this limits the numberof cells which can grow into t...

Enzyme, lost in most mammals, is shown to protect against UV-induced skin cancer

...UV-induced DNA damage, which for example may occur after excessiveunprotected sunbathing, can lead to cellular death ?recognized assunburn of the skin ?and may cause permanent changes in the DNA(mutations) that ultimately can result in the onset of skin cancer.Thus far it was not clear how the two major ty...

Wells and his colleagues are evaluating the data they collected and conducting additional laboratory experiments. UM...

Poor prenatal nutrition permanently damages function of insulin-producing cells in the pancreas

...the researchers tested their blood glucose (sugar) after meals. At age 2 months, the results were similar between the two groups. But over time, differences began to unfold. When 4 months old (comparable to human adolescence), the low-birth-weight babies began showing higher levels of blood glucose. "By 6 ...

Controversial drug shown to act on brain protein to cut alcohol use

...The discovery that Ibogaine reduced binge drinking after a period ofabstinence was an exciting finding for us because this is the type ofbehavior in alcoholics for which very few effective drugs exist," Janaksaid.The scientists confirmed in a cell model that Ibogaine stimulated GDNFactivity. Finally, they ...

Elusive HIV shape change revealed; Key clue to how virus infects cells

...ell and begin replicating. The structure of gp120 after it binds to the CD4 receptor and changes its shape was solved several years ago by another group. Harrison and Chen have now described gp120's structure before the shape change, yielding vital before-and-after information on how the molecule rearrang...

Whilst rising air temperatures are believed to be the primary cause of recent dramatic disintegration of ice shelves like Larsen B, the new study suggests that the ocean may play a more significant role in destroying them tha...

Epstein thinks that this concept may also be important for understanding the cell of origin for a number of tumors. Pax3 is known to be involved i...
