CRISPR

In the late 1980s and mid-1990s, genomes of diverse lineages of bacteria and archaea (the latter representing a domain of single-celled prokaryotic microorganisms) revealed clusters of regularly interspaced short palindromic repeats, known today under the abbreviation CRISPR. Later it was found that these repeat sequences (previously considered disparate) share a common set of features.

CRISPR: Ethical and Safety Concerns

CRISPR and Cas proteins have become a crucial tool for genetic manipulation in biomedical research and biotechnology, and the crux of its action is the recognition of specific sequences in the DNA and their subsequent cleavage from the chain. One specific system, CRISPR-Cas9, has become the standard for genetic editing, since it can be tailored to target any set of DNA sequences. Thus it is of no wonder that it caused an upheaval in biomedical field.

Salk researchers shed new light on specific mechanisms that activate oncogenes

Cancer, caused by abnormal overgrowth of cells, is the second-leading cause of death in the world. Researchers from the Salk Institute have zeroed in on specific mechanisms that activate oncogenes, which are altered genes that can cause normal cells to become cancer cells.

Researchers develop 3D organoid model to advance understanding of gastroesophageal junction cancer

Researchers at Johns Hopkins Medicine say they have created a laboratory-grown three-dimensional "organoid" model that is derived from human tissue and designed to advance understanding about how early stages of cancer develop at the gastroesophageal junction (GEJ) — the point where the digestive system's food tube meets the stomach.

Stem cell crosstalk with the microenvironment creates a loop of tumor-promoting factors

What drives tumor growth? Is it a few rogue cells imposing their will upon healthy tissue, or diseased tissue bringing out the worst in otherwise peaceable cells? Or is it a back-and-forth, a dialogue between the two?

Study reveals mechanism by which malignant cells shut down anti-cancer immune responses

A Ludwig Cancer Research study has revealed a single protein expressed at high levels by cancer cells across a broad range of malignancies that erects a multifaceted barrier to anti-cancer immune responses in mouse models of cancer and so shields tumors from immune detection and destruction.
