Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Common antibiotic can improve survival and neurological outcomes in CNS-TB

Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have demonstrated that doxycycline, a commonly available and inexpensive antibiotic, can improve survival rates and neurological outcomes in Central Nervous System Tuberculosis (CNS-TB) in a preclinical non-human study.

AI chat box helps investigate complex biology in English language

Using sophisticated RNA sequencing technology, biomedical researchers can measure the activity of our genes across millions of single cells, creating detailed maps of tissues, organs, and diseases.

Study advances the possibility of age-based pancreatic cancer treatment

While some risk factors for cancer can be mitigated through lifestyle choices such as diet or exercise, aging is not one of them. In the case of pancreatic cancer, it also can limit treatment options if a patient is too frail to be safely treated with surgery or other alternatives.

One-time CRISPR therapy safely lowers cholesterol and triglycerides in early trial

In a 15-patient, Phase 1 one, first-in-human trial, a one-time, CRISPR-Cas9 gene-editing therapy safely reduced LDL cholesterol and triglycerides in people with difficult-to-treat lipid disorders, according to a preliminary late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.

Maternal type 1 diabetes may protect children from developing the disease

Findings suggest maternal T1D exposure leads to protective epigenetic alterations in children, influencing immune response and type 1 diabetes susceptibility.

Machine learning advances human-centric drug toxicity prediction

In the UK, there was a case where TGN1412, an immunotherapy under development, triggered a cytokine storm within hours of administration to humans, leading to multiple organ failure.

Alzheimer’s breakthrough reveals how tweaking one gene shields brain connections

Lowering the transcription factor PU.1 reprograms microglia into a neuroprotective, lymphoid-like state that compacts amyloid, blocks tau spread, and preserves synapses in Alzheimer’s disease. Microglial CD28 signaling helps restrain inflammation, revealing a regulatory switch that may inform future immunotherapies targeting microglia rather than neurons.

Study identifies molecular brake that controls overactive killer T cells

"Why do immune cells that are supposed to eliminate viruses suddenly turn against our own body?"

Newly identified microglia subtype offers protection against Alzheimer’s disease

In Alzheimer's disease, the leading cause of dementia, microglia-the brain's immune defenders-can act as both protectors and aggressors, shaping how the disease progresses.

PTGES3 emerges as key regulator of androgen receptor in prostate cancer

A poorly characterized protein, historically thought to be a chaperone or enzyme, may actually be a key player in prostate cancer.

Stress hormones may silence crucial neuronal genes through specific RNA molecules

What if the brain's response to stress could be read not in fleeting neurotransmitter bursts, but in the quieting of genes deep inside chromatin? Researchers at the University of Alabama at Birmingham have now shown that stress hormones may silence crucial neuronal genes through an unexpected class of RNA molecules that operate not by encoding proteins, but by reshaping the genome's architecture.

How walnuts combat inflammation and oxidative stress in the body

This review in Food Science & Nutrition synthesizes evidence showing that walnuts (Juglans regia L.) exert potent antioxidant, anti-inflammatory, apoptosis-regulatory, and immunomodulatory effects through bioactive compounds influencing mitochondrial, cytokine, and redox pathways.

Large-scale foundation model reconstructs how cells interact within tissues

Researchers at Helmholtz Munich and the Technical University of Munich (TUM) have developed Nicheformer, the first large-scale foundation model that integrates single-cell analysis with spatial transcriptomics.

Researchers develop a versatile tool for controlling gene activity

Investigators at Weill Cornell Medicine have developed a versatile and non-toxic technology for controlling the activity of any gene in a cell. Such "gene-switch" tools allow scientists to "turn on" or "turn off" a target gene to study how it works, model diseases and design new therapies.

Neuroscientists uncover a surprising role for "Frazzled" protein in the nervous system of fruit flies

Florida Atlantic University neuroscientists have uncovered a surprising role for a protein named "Frazzled" (known as DCC in mammals) in the nervous system of fruit flies, showing how it helps neurons connect and communicate with lightning speed.

Thiostrepton suppresses rhabdomyosarcoma progression by targeting the PI3K–AKT pathway

Rhabdomyosarcoma (RMS) accounts for up to 10% of childhood cancers and nearly half of pediatric soft tissue sarcomas.

Understanding the role of m6A methylation in acute lung injury pathogenesis

Acute lung injury (ALI) is a critical clinical condition characterized by diffuse inflammation of the lung parenchyma and intractable hypoxemia, typically caused by factors, such as trauma, pneumonia, shock, and sepsis.

Does fasting earlier in the day improve metabolism? This study says no

In a randomized crossover trial of 31 women with overweight, early and late time-restricted eating (TRE) produced no improvement in insulin sensitivity or cardiometabolic markers under isocaloric conditions. Both schedules, however, shifted internal circadian clocks, highlighting that meal timing affects biological rhythms more than metabolic outcomes.

Understanding age-related changes in T cells and vaccine response

As flu season approaches and public health officials roll out their annual push for vaccination, Allen Institute scientists are learning why vaccines can trigger a weaker response in older adults, around age 65, and what can be done to improve them.
