Study demonstrates for the first-time neurons moving in postnatal neurogenesis

A study published recently in the Journal of Cell Biology has described how newborn precursor neurons, termed neuroblasts, which originated in a permanent pocket of stem cells in an area of the brain called the V-SVZ—traveled from their birthplace to a target destination in the olfactory bulb via a special tunnel called the RMS.

Inner workings of cells probed by new Kleindiek nanomanipulator at UNSW

The mechanism of how cells work is key to understanding how tumours metastasize as well as tissue regeneration and other bodily functions. The process of mechanotransduction, or how a cell converts a physical stimuli into an electrical response is fundamental to these understandings.

Timing of DNA damage within checkpoints matters to a cell's fate, study reports

DNA damage occurs routinely within your cells due to sun exposure, smoking and sometimes during the normal process of making new DNA.

Scientists develop physiological approach to restore gut’s ecosystem in various diseases

The trillions of microbes living in a mammal's intestine play an important role in the host's metabolism and immunity. The composition of microbiota is maintained by antimicrobial proteins secreted from intestinal cells.

Gene circuit can be used to switch on inside cancer cells and stimulate immune attack, study suggests

A new study, conducted by researchers at MIT, suggests that a recently developed synthetic gene circuit can stimulate the immune system to kill cancer cells when it identifies indications of the cancer. The gene circuit will only stimulate a therapeutic response when it identifies two particular cancer markers.

Scientists uncover surprising molecular link in critical cellular growth pathway

A team of scientists led by Whitehead Institute has uncovered a surprising molecular link that connects how cells regulate growth with how they sense and make available the nutrients required for growth.

Genetic diversity plays major role in evolution of drug resistance

Researchers have shown that genetic diversity plays a key role in enabling drug resistance to evolve. Scientists at the Wellcome Trust Sanger Institute and the Institute for Research on Cancer and Ageing of Nice in France, show that high genetic diversity can prime new mutations that cause drug resistance.

Using AFM to study cell mechanics and function

My lab, broadly speaking, is interested in trying to understand interactions between cells and materials. Those could be materials that are present within living tissue or materials that we use for engineering purposes to try to do something of technological or therapeutic interest.

Columbia scientists receive grant from CZI to construct atlas of cells in human spinal cord

Scientists at Columbia's Zuckerman Institute today received a grant from the Chan Zuckerberg Initiative donor advised fund, an advised fund of the Silicon Valley Community Foundation, to construct an atlas of gene activity of all cells in the human spinal cord.

Investigating new cancer therapy candidates with live-cell imaging

There are two main things that we've worked on in the lab as regards to drug studies. One is identifying new combinations of drugs, and working on why a combination of drugs should work better than each alone.

Specific regions of silenced DNA help define cell's identity, study suggests

The fundamental mechanisms governing how cells form an identity such as becoming a muscle cell or a nerve cell are not fully understood. Multiple diseases, including cancer, have been linked to cells going down the wrong developmental path during maturation.

New x-ray analysis methodology reveals structure of disordered protein

Scientists at The University of Notre Dame have shown that disordered proteins have a structure very close to what would be expected for a truly random structure using a novel X-ray scattering (SAXS) analysis methodology.

Researchers use mixed realty viewer to visualize complex biological networks in 3D

They call it the "hairy ball." It's an unflattering name for two-dimensional representations of a complex biological network, a depiction of a system of linkages and connections so complex and dense that "it looks like a big mess," said Dmitry Korkin, PhD, associate professor of computer science at Worcester Polytechnic Institute and director of the university's bioinformatics and computational biology program.
