Epigenetic research provides new approaches to cancer combination therapies

Epigenetic processes enable cells to respond to changes in their environment by regulating the activity of their genes.

Researchers discover unexpected survival mechanism of a subset of cancer cells

Embedded at the end of chromosomes are structures called "telomeres" that in normal cells become shorter as cells divide. As the shortening progresses it triggers cell proliferation arrest or death. Cancer cells adopt different strategies to overcome this control mechanism that keeps track of the number of times that a cell has divided.

Scientists use gold nanoparticles to edit genes tied to HIV, inherited blood disorders

Scientists at Fred Hutchinson Cancer Research Center took a step toward making gene therapy more practical by simplifying the way gene-editing instructions are delivered to cells.

Genetically eliminating TOX factors improves eradication of solid tumors in CAR T model

A decade ago researchers announced development of a cancer immunotherapy called CAR (for chimeric antigen receptor)-T, in which a patient is re-infused with their own genetically modified T cells equipped to mount a potent anti-tumor attack.

Mites and ticks are part of the same evolutionary line, research shows

Scientists from the University of Bristol and the Natural History Museum in London have reconstructed the evolutionary history of the chelicerates, the mega-diverse group of 110,000 arthropods that includes spiders, scorpions, mites and ticks.

Researchers discover new function of ribosomes in human cells

Researchers from the Stowers Institute for Medical Research have discovered a new function of ribosomes in human cells that may show the protein-making particle's role in destroying healthy mRNAs, the messages that decode DNA into protein.

Prostate cancer marker activates growth factors that contribute to tumor spread

A new study indicates that PSA, a prostate cancer marker, is one of the catalysts that activate vascular endothelial and lymphangiogenic growth factors which contribute to the spread of cancer.

Are fruit fly 'avatars' the next step in personalized medicine?

Researchers have created fruit fly “avatars” that have helped to guide treatment for a man who had terminal colon cancer.

Cell scientist receives $1.9 million NIH grant to study muscle regeneration

As people age, their muscle regeneration capacity declines in part because they can no longer make enough muscle stem cells to replace damaged tissue.

Johns Hopkins researchers develop method to map retinal cell development

Johns Hopkins Medicine researchers report they have created a method of mapping how the central nervous system develops by tracking the genes expressed in cells.

Rutgers-led study pinpoints key gene linked to impaired memory in Down syndrome

Targeting a key gene before birth could someday help lead to a treatment for Down syndrome by reversing abnormal embryonic brain development and improving cognitive function after birth, according to a Rutgers-led study.

Researchers map bone-marrow microenvironment to shed new light on leukemia

Stem cells are surrounded and protected by the stem-cell niche - the microenvironment - of the tissue in which they are found.

New lithography method for producing complex tissues and organs

The production of artificial organs is a hot research topic. In the near future, artificial organs will compensate for the lack of organ donations and replace animal experiments.

Spatial configuration of the genome is not inherited, but set up during embryogenesis

The architecture of the DNA-protein complexes that make up the genome in each cell nucleus regulates the course of early embryonic development.

Scientists uncover unique set of genes that play a role in muscle cellular gene regulation

York University scientists have uncovered a unique set of genes that play a role in muscle cellular gene expression and differentiation which could lead to new therapeutic targets to prevent the spread of muscle cancer.

Newly discovered molecules safely halt the gene editing process

Scientists have discovered two non-toxic molecules that safely halt the CRISPR-Cas9 gene editing process.

Scientists unravel how DNA organizes and preserves genetic information

Two scientists at the Johns Hopkins University School of Medicine have unraveled aspects of how DNA organizes and preserves genetic information.

UW researchers use molecular tethers, chemical 'light sabers' for tissue engineering

Tissue engineering could transform medicine. Instead of waiting for our bodies to regrow or repair damage after an injury or disease, scientists could grow complex, fully functional tissues in a laboratory for transplantation into patients.

Researchers decode how molecular escorts help prevent cancer

The anti-tumor protein p53 can decide on the life or death of a cell: If it detects damage in the cell's genome, the protein pushes the cell to suicide.

Study provides new insights into key beneficial function of small ancient protein

Cell boundaries are made of lipids. When cells are severely damaged, these lipids need to be rapidly removed to avoid toxicity and facilitate tissue healing. Researchers have discovered that a small ancient protein, Serum Amyloid A (SAA), plays a previously unknown key role in this vital process.
