New scLS algorithm advances gene expression trajectory analysis

Single-cell RNA sequencing (scRNA-seq) is a method to measure gene expression of individual cells, allowing observation of various cellular processes, including cell differentiation, the cell cycle, and stimulus-response for each unique cell instead of averaging across millions of cells.

Lifestyle factors aggravate genetic causes of male infertility, study finds

Lifestyle factors can worsen the effects of genetic causes of male infertility, finds new research that could help explain why men carrying similar genetic mutations often experience different levels of fertility impairment.

Does a psychedelic need an awake brain to have lasting effects? This mouse study offers a clue

A single dose of psilocybin produced a lasting increase in sociability for at least two weeks in Cntnap2-knockout mice with social deficits, while it did not enhance sociability overall in mice with normal social behavior. The effect required 5-HT2A receptor activation and persisted when psilocybin was administered under light anesthesia, suggesting that wakefulness during the drug’s acute effects was not necessary for this behavioral response.

Faulty myelin-making brain cells may help drive cognitive decline with age

Researchers found that greater age-related cognitive decline was associated with more dysfunctional oligodendrocytes, reduced NRF2 expression, smaller myelinated axons, and abnormally thicker myelin in human white matter. Experiments in mice showed that deleting NRF2 specifically from oligodendrocytes reproduced key white matter abnormalities and reduced cognitive improvement over time, implicating this pathway in cognitive aging.

Gene removal makes engineered immune cells more effective against osteosarcoma

Scientists at St. Jude Children's Research Hospital have discovered that removing the gene for Regnase-1 from engineered immune cells makes them more effective at treating relapsed osteosarcoma.

New review challenges the eight-hour ancestral sleep myth

Everyone knows the number. Eight hours. It sits on wellness dashboards, on pediatric handouts, on the label of the melatonin bottle in the medicine cabinet.

Mitochondrial protein deficiency drives increased fat intake and obesity

Obesity is a global health concern that can contribute to diabetes, cardiovascular disease, and other metabolic disorders.

Researchers suggest a potential therapeutic strategy for muscle loss associated with obesity

Obesity has been linked to skeletal muscle loss and deterioration. While M2 macrophages may play a role in regulating muscle function, the underlying mechanisms remain poorly understood.

Major clinical trial aims to transform the prevention of recurrent urinary tract infections

European-funded consortium brings together researchers from 13 countries to evaluate bacteriophage therapy as a potential alternative to antibiotics for recurrent urinary tract infections.

Thymulin curbs age-related inflammation and slows breast tumors in mice

Thymulin reduced age-associated inflammatory myeloid cells and slowed breast-tumor growth in aged mice by suppressing NF-κB signaling. The peptide also restored anti-PD-L1 responsiveness in aged mouse models, while human cell and tumor data supported an age-linked inflammatory myeloid profile.

Experimental gene therapy reverses fragile X symptoms in mice

A gene therapy designed to replace the missing protein that causes fragile X syndrome restored several disease-relevant traits in a mouse model, according to a new study published in Gene Therapy.

Myotonia may play a much larger role in driving muscle damage than previously recognized

For decades, researchers studying myotonic dystrophy type 1 (DM1) have focused on the disease's underlying genetic cause: a mutation that produces a toxic form of RNA, disrupting the normal processing of thousands of genetic messages inside cells.

Study reveals distinct roles of oxygen-sensing proteins in skeletal muscles

Skeletal muscles-responsible for movement, joint stabilization, and postural support-are highly metabolically active and heavily reliant on oxygen during physical activity.

Niche-targeted therapies offer a fresh approach to regenerative medicine

A healthy bone marrow (BM) produces nearly all types of cells in our blood. Many blood disorders occur when hematopoietic stem cells (HSCs) in the BM malfunction.

Toronto researchers uncover genetic drivers of triple negative breast cancer

Researchers have solved a long-standing mystery of how abnormal chromosomes drive cancer, identifying 81 new genes involved in aggressive breast cancer.

Discovery provides key insights into cellular mechanisms underlying female fertility

Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles. Within these follicles, the oocyte is surrounded by granulosa cells that supply nutrients, signaling molecules, and structural support essential for egg development.

Nasal viruses may drive allergic rhinitis, and ribavirin shows early promise as a targeted spray treatment

Nasal commensal viruses may worsen allergic rhinitis by activating type I IFN-linked neutrophils and NET formation. Ribavirin reduced nasal viral abundance and improved symptoms in mice and in a small phase 2 trial.

Lactate and lactylation play multifaceted roles in pancreatic ductal adenocarcinoma

A comprehensive review recently published in Current Molecular Pharmacology illuminates the pivotal, multifaceted roles of lactate and its downstream protein modification, lactylation, in pancreatic ductal adenocarcinoma (PDAC).

Gene linked to lower BMI points researchers toward a new obesity target

A review in Cardiology in Review highlights GPR75, a receptor for 20-HETE, as a promising therapeutic target for obesity and metabolic syndrome. Evidence from genetic studies, cell experiments, and mouse models suggests that blocking this pathway could influence weight gain, insulin resistance, hypertension, inflammation, and vascular dysfunction.
