Gene

A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

What are Genes?

Deoxyribonucleic acid (DNA) is the chemical information database that carries the complete set of instructions for the cell as to the nature of the proteins produced by it, its life span, maturity, function and death. Genes are the working subunits of DNA. Each gene contains a particular set of instructions, usually coding for a particular protein or for a particular function.

Coffee, citrus and genetics: What scientists found inside human breast milk

In a bioRxiv preprint, researchers analyzed 458 metabolites in breast milk samples from 349 mothers to investigate how maternal diet, genetics, clinical characteristics, and milk-cell gene expression relate to milk composition. Maternal diet explained the greatest share of metabolite variation among the measured maternal factors, while specific genetic variants and gene-expression patterns were associated with individual metabolites, although the study did not establish effects on infant health.

Cigarette smoke exposure alters ovarian and testicular function in mice

New research has shed light on how exposure to cigarette smoke could affect reproductive health in both men and women, identifying changes in biological processes involved in ovarian function and sperm production.

Researchers uncover how metastatic colorectal cancer evades immune attack

Researchers at Hokkaido University, in collaboration with an international team of scientists led by the University of South Florida Health and Tampa General Hospital, have uncovered an important mechanism behind immune evasion in metastatic colorectal cancer (mCRC).

Researchers improve CRISPR technology for detecting HIV and other RNA viruses

Scientists have long used a powerful gene-editing tool called CRISPR to make precise changes to DNA. But a different version of the technology, known as Cas13a, targets RNA, the genetic material found in viruses such as HIV.

$5.8 million study explores gut-brain inflammation in people with HIV

Oregon Health & Science University researchers have secured a $5.8 million, five-year federal award to investigate whether damage to the gastrointestinal tract contributes to neuroinflammation in people living with HIV - raising the potential for new treatments to preserve brain function in people with HIV and older adults.

CHOP researchers link MAP2K4 variants to a neurodevelopmental disorder

Researchers from Children's Hospital of Philadelphia (CHOP) have discovered the mechanisms of previously unknown changes in a gene that result in symptoms associated with a neurodevelopmental disorder.

Pancreatic cancer cells continuously reshape DNA to evade treatment

A new analysis of nearly half a million cells from dozens of pancreatic tumors, led by researchers at UC San Diego Moores Cancer Center and New York University (NYU), reveals how pancreatic cancer cells continuously reshape their genetic makeup over time, enabling them to evade treatment.

Single-cell analysis reveals how pancreatic cancer evades treatment

An analysis of nearly half a million cells from dozens of patients' tumors reveals how cancer cells continuously reshape their genetic makeup over time, enabling them to evade treatment for one of the deadliest forms of cancer.

New research shows reduced toxicant exposure reduces biological activity

Two newly published studies from Imperial Brands scientists have provided further evidence that products associated with lower levels of combustion-related toxicants also produce substantially lower levels of combustion-related toxicants also produce substantially lower biological activity than cigarette smoke under laboratory conditions.

Gene therapy and special goggles help some blind adults detect objects again

In a phase 1 study of 10 adults with advanced retinitis pigmentosa, researchers found that optogenetic gene therapy combined with light-stimulating goggles was generally well tolerated, although one participant experienced a severe but transient ocular adverse event. Seven participants showed improved light sensitivity, while four of eight who completed behavioral testing demonstrated modest gains in visual function, providing preliminary evidence of partial vision restoration that requires confirmation in larger controlled trials.

Three months of yoga before surgery revealed a surprising difference in stress hormones

In a non-randomized study of 40 adults with severe obesity awaiting bariatric surgery, researchers found significantly lower plasma noradrenaline levels in yoga participants than in controls after adjusting for baseline measurements. The researchers detected no significant DNA methylation changes in three inflammatory genes and found no clear psychological or metabolic benefits.
