Fat fuels the road to cancer cell spread

Posted: 26 Dec 2016 06:13 PM PST

Cancer cells spread to other sites in the body through promoting the growth of new 'roads' to travel on. Scientists have discovered how a shift to increased fat utilization is required for the development and growth of these 'roads,' termed lymphatic vessels -- a special kind of blood vessels.

Nanodiscs deliver personalized cancer therapy to immune system

Posted: 26 Dec 2016 06:12 PM PST

Researchers have had initial success in mice using nanodiscs to deliver a customized therapeutic vaccine for the treatment of colon and melanoma cancer tumors.

Engineers create programmable silk-based materials with embedded, pre-designed functions

Posted: 26 Dec 2016 06:12 PM PST

Engineers have created a new format of solids made from silk protein that can be preprogrammed with biological, chemical, or optical functions, such as mechanical components that change color with strain, deliver drugs, or respond to light.

Synthetic stem cells could offer therapeutic benefits, reduced risks

Posted: 26 Dec 2016 06:12 PM PST

Researchers have developed a synthetic version of a cardiac stem cell. These synthetic stem cells offer therapeutic benefits comparable to those from natural stem cells and could reduce some of the risks associated with stem cell therapies. Additionally, these cells have better preservation stability and the technology is generalizable to other types of stem cells.

Research reveals the importance of long non-coding RNA regulating cellular processes

Posted: 26 Dec 2016 06:12 PM PST

Scientific research over the past decade has concentrated almost exclusively on the 2 percent of the genome's protein coding regions, virtually ignoring the other 98 percent. Investigators now reveal that long non-coding RNA (lncRNA) may be critically important for controlling cellular components in a tissue-specific manner, with new research pointing to an lncRNA's key role in helping control processes related to muscle regeneration and cancer.

Experimental therapy for Prader-Willi syndrome shows promise in mice

Posted: 26 Dec 2016 06:12 PM PST

Drugs capable of activating silenced genes improve survival and growth outcomes in a mouse model of Prader-Willi syndrome (PWS), a rare and incurable childhood disease.

Naturally occurring mechanism of cancer drug-resistance may itself be a treatment target

Posted: 26 Dec 2016 06:09 PM PST

The use of proteasome inhibitors to treat cancer has been greatly limited by the ability of cancer cells to develop resistance to these drugs. But researchers have found a mechanism underlying this resistance -- a mechanism that naturally occurs in many diverse cancer types and that may expose vulnerabilities to drugs that spur the natural cell-death process.

Dental implants with antibacterial activity and designed to facilitate integration into the bone

Posted: 26 Dec 2016 02:53 PM PST

Scientists are developing coatings for dental implants to help ensure successful implantation.

Novel drug may help repair failing hearts

Posted: 26 Dec 2016 02:53 PM PST

Cimaglermin, a new experimental drug, may help restore cardiac function after heart failure, according to a first-in-man study.
