Gene-regulatory factors shown to improve pancreatic cancer response to chemotherapy

Researchers revealed that, in pancreatic cancer, the microRNAs miR-509-5p and miR-1243 can promote E-cadherin expression and thereby reduce the likelihood of cells undergoing epithelial-mesenchymal transition, or indeed reverse this transition. This ability to stop cells from adopting a phenotype linked to high migration and invasiveness was also shown to synergistically increase the cancer cell-killing efficacy of gemcitabine, which is promising for developing more effective combinatorial treatments for pancreatic cancer.

Can insects be used as evidence to tell if a body has been moved?

The use of insects as indicators of post-mortem displacement is a familiar technique depicted on many crime investigation TV shows. In reality, this practice is far from clear-cut. To cut through the hype, researchers have looked across existing studies to review how exactly insects have been used in legal investigations and to what extent these methods have been useful.
