Cannabis use may alter gene linked to autism in male sperm

Researchers from Duke University Medical centre, Durham, USA have come up with an important study that shows that use of cannabis among men could alter a specific gene in their sperm that is linked to autism. The study titled, “Cannabis use is associated with potentially heritable widespread changes in autism candidate gene DLGAP2 DNA methylation in sperm,” and is published in the latest issue of the journal Epigenetics.

New study helps explain why lung tumors turn aggressive

Lung cancer is the number 1 killer among cancers, especially when it is of the non-small cell type. Among these, adenocarcinomas are the most common and aggressive type. These tumors also show a strong tendency to show dedifferentiation, or loss of the features that characterize a mature lung cell.

Researchers find a weak spot in cancer cells

Cancer cells form tumors. This statement, simple as it seems, hides a complex failure of normal immune responses that should eliminate tumor cells from the body before they ever form viable cancer masses.

Promising vaccine may protect against the Klebsiella superbug

A powerful superbug, a hypervirulent form of the bacteria Klebsiella pneumoniae, is a very difficult to curb infection. It causes a variety of infections including rare but life-threatening liver, respiratory tract, bloodstream and other infections.

Novel immunotherapy method could overcome tumor immunity

Cancer immunotherapy is a form of treatment in which the body’s own immune cells are recruited to overcome the tumor. However, it is only useful in a few tumors, because of tumor immunity where tumor-associated immune cells work to protect the tumor against attack.
