Sentences with phrase «alter cell processes»

Because DNA is encoded with the instructions for cell behavior, damaged DNA can alter cell processes including those that regulate growth and division.

Not exact matches

Vitamin A and vitamin D are precursors to hormones that influence biological processes by entering the nucleus of a cell, binding to DNA, and altering the transcription of certain genes.

The natural structures that exist either between cells or within cells are damaged during the freeze - thaw process and hence the flavor or texture of the tissue is altered.

Unlike genetic mutations that affect DNA and the genome, epigenetic markers turn genes on and off to regulate cell processes, which if altered may lead to disease, he explains.

A strategic focus is to continue to develop computational tools (such as KinomeXplorer, NetworKIN, and NetPhorest) and to deploy these on genome - scale quantitative data obtained by, for example, mass spectrometry, genomic, and phenotypic screens to understand the principles of how spatio and temporal assembly of mammalian signaling networks transmit and process information at a systems level in order to alter cell behavior.

Not only do brain cells alter their connections, but additional neurons can also spontaneously form, a process called neurogenesis.

Using lung cancer cells and mice the scientists showed that the combination of two drugs, called TRAIL and a CDK9 inhibitor, altered the molecular switches in the cell suicide process — forcing the cancer cells to self - destruct.

Since HIV infection itself alters epigenetic processes in the immune system, the research team wondered whether a distinct DNA methylation profile, a major epigenetic modification where methyl groups are added to DNA, occurs in those with HIV associated - cognitive impairment and whether it exists in distinct immune cell populations from the blood.

The team found they could replicate the healing abilities of the engineered mice by giving nongenetically altered ones drugs that help activate certain metabolic processes — the same pathway Lin28a stimulates — revving up and energizing cells as if they were much younger.

These so - called «living drugs» — injected T cells genetically modified to better recognize and kill tumor cells through a perpetual process of cell renewal and expansion — are revolutionizing cancer treatment, with the first two FDA approvals of such gene - altering therapies occurring in just the last two months.

Pseudotyping is the process of producing viruses with foreign envelope proteins and is frequently used to generate viruses with altered cell tropism [Cronin et al., 2006].

During this process, the virus alters its appearance and our immune memory cells struggle to recognise it, leaving the virus free to infect us once more.
