Amino Acid is one of several molecules that join together to form proteins. There are 20 common amino acids found in proteins.

Five mutation patterns shape how cancers evade immunity

Cancer cells carry thousands of mutations, but not all mutations are created equal. Some make tumors highly visible to the immune system, while others help cancers hide.

Aging brains struggle to recycle synaptic proteins

As we age, we begin to lose the connections that wire up our brains-and neuroscientists aren't sure why.

Lower hinge of immunoglobulin G acts as a critical immune control hub

The lower hinge of immunoglobulin G (IgG), an overlooked part of the antibody, acts as a structural and functional control hub, according to a study by researchers at Science Tokyo.

Gut microbiome may be a central player in the body's response to cancer

A new study reveals how bacteria in the gut can help determine whether the amino acid asparagine from the diet will feed tumor growth or activate immune cells against the cancer, according to researchers at Weill Cornell Medicine.

Brain-specific enzyme drives branching and extension of O-mannose glycans

Gifu University scientists have uncovered how a brain-specific enzyme reshapes protein-linked sugar chains to facilitate the formation of complex glycans essential for normal brain function.

How modern lifestyles reprogram the gut microbiome and shape disease risk

Modern lifestyle factors such as circadian disruption, sleep deprivation, stress, and exercise reshape the gut bacteriome and its metabolic outputs. These microbiome changes are linked to immune, metabolic, and cancer-related pathways, largely through evidence from animal models and observational human studies.

Why eating more oats can rapidly reduce cholesterol levels

Oat consumption boosts gut microbiota-derived phenolic metabolites, driving cholesterol-lowering effects and improving lipid metabolism in metabolic syndrome.

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

Metabolic reprogramming drives prostate cancer progression and treatment resistance

Prostate cancer (PCa) is one of the most common malignant tumors among men worldwide. Following androgen deprivation therapy (ADT), the disease often progresses to castration-resistant prostate cancer (CRPC).

Short-term oatmeal diet improves cholesterol and metabolic health markers

A short-term oat-based diet appears to be surprisingly effective at reducing the cholesterol level. This is indicated by a trial by the University of Bonn, which has now been published in the journal Nature Communications.

Ageing slows brain protein clearance and shifts synaptic waste to microglia

Ageing slows neuronal protein degradation in mice, leading to widespread accumulation and aggregation of long-lived proteins, particularly at synapses. As neuronal clearance declines, microglia selectively accumulate synaptic proteins, suggesting a compensatory but potentially strained proteostasis pathway in the ageing brain.

Methionine: A dietary key to surviving infection

As soon as you are wounded-whether from grabbing a hot pan or contracting the flu-you begin a unique journey through variable symptoms toward either recovery or death.

Myosteatosis: An emerging predictor of outcomes in chronic liver disease

Myosteatosis, the pathological infiltration of fat into skeletal muscle, is increasingly recognized as a key predictor of poor clinical outcomes across a spectrum of liver diseases.

Algae may help meet future protein demand without straining the planet

This narrative review evaluates clinical evidence on algae and algal proteins as sustainable, nutrient-dense food sources with high protein quality and bioactive compounds. Findings suggest potential benefits for muscle protein synthesis, cardiometabolic markers, immune modulation, and antioxidant status, while emphasizing heterogeneity, short-term data, and the need for longer clinical trials.
