Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

How the nutrient cysteine controls cancer-fighting power of T cells

A research team from the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health have discovered how the immune system's CD8+ T cells use the nutrient cysteine to control two essential functions that compete for this resource - the immune cell's ability to multiply and its ability to kill cancer cells.

Study reveals ALDH2 vulnerability in APC-deficient colorectal cancer

A precision cancer strategy that selectively kills tumour cells while leaving healthy tissue intact may be within reach for the majority of colorectal cancer patients, according to new research published in Genes & Disease.

Terahertz radiation alters metabolism and signaling in melanoma cells

Terahertz (THz) radiation is increasingly explored for biomedical applications, however, its non-thermal effects on cellular metabolism and regulatory networks remain insufficiently characterized.

Study reveals immune changes in HIV and HCV coinfected patients

Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) coinfection leads to severe systemic inflammation, increasing non-AIDS morbidity and mortality risk. CD39 ectoenzyme on T-cells, which catalyzes the conversion of pro-inflammatory purines to immunosuppressive adenosine, plays an important role in inflammation control.

Study reveals how inflammation disrupts lymph node structure in lymphoma

In aggressive lymphomas, inflammatory messengers reprogram the "conductors" of the immune system, causing lymph nodes structure to collapse.

The molecular mechanism that turns cool temps into nerve signals

When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" signal to your brain.

Study identifies rare genetic disorder linked to premature aging and cognition

Scientists at Sanford Burnham Prebys Medical Discovery Institute and an international team of collaborators have defined a new genetic disease marked by premature aging and deficits in brain function.

Mediterranean diet may protect health through mitochondrial microproteins

A new study led by researchers at the USC Leonard Davis School of Gerontology suggests that the benefits of the Mediterranean diet may be driven, in part, by tiny proteins hidden within our mitochondria, opening a new window into how diet shapes aging and disease risk.

NAC complex initiates early protein folding in human cells

In the earliest phase of creating human proteins, the protein complex NAC performs an essential task by starting the first steps towards folding proteins into their correct three-dimensional structures.

AI-driven atlas reveals how mouth fibroblasts regulate structural immunity

Researchers at VCU Massey Comprehensive Cancer Center are leading an international study that advances the understanding of the immunoregulatory nature of human tissues, offering breakthrough insights into how fibroblasts serve as the core regulators of structural immunity in the mouth.

Study identifies protein that slows cartilage breakdown in joints

Osteoarthritis, a condition that causes pain and reduced mobility in joints such as the knees and fingers, is one of the most common joint disorders worldwide, particularly among aging populations.

New mechanism drives adverse tumor remodeling during breast cancer progression

A research group led by Professor Cecilia Sahlgren at Åbo Akademi University (Finland) and the InFLAMES Research Flagship has identified a new mechanism directing the adverse remodeling of tumor tissue during breast cancer progression.

AlphaFold Database expands with millions of predicted protein complexes

A new collaboration between EMBL's European Bioinformatics Institute (EMBL-EBI), Google DeepMind, NVIDIA, and Seoul National University has made millions of AI-predicted protein complex structures openly available through the AlphaFold Database.

Study reveals how disordered proteins function without stable structure

A new LMU study shows how proteins function reliably even without a stable 3D structure – and the crucial importance not only of short sequence motifs, but also of the chemical characteristics.
