University of Warwick research warns that popular deep learning systems trained for cancer pathology may be relying on hidden shortcuts rather than genuine biological signals.

A novel bioengineering strategy utilizing peptide display technology on the AAV1 capsid has successfully generated next-generation viral vectors with significantly enhanced specificity and efficiency for inner ear cell transduction, offering a promising advance toward targeted gene therapies for hearing and balance disorders.

Aging is a major risk factor for chronic diseases, and calorie restriction (CR) is a robust non-pharmacological intervention that can extend health span in multiple species. Alternative splicing (AS) generates multiple RNA isoforms from a single pre-mRNA and becomes dysregulated with age; intriguingly, prior work suggests that CR can attenuate age-associated splicing noise. What has remained unclear is whether AS responses to CR are coordinated across tissues and whether they scale with the level of restriction.

Atherosclerosis represents a chronic inflammatory disease characterized by the accumulation of lipid-laden macrophage foam cells within arterial walls, serving as the underlying pathological basis for cardiovascular diseases including myocardial infarction and stroke. Despite significant advances in understanding the molecular mechanisms driving atherogenesis, novel therapeutic targets remain urgently needed to address the persistent global burden of cardiovascular disease. A research study by Fengchan Li and colleagues identified macrophage-derived semaphorin 7A (SEMA7A) as a critical driver of atherosclerosis progression through a previously unrecognized signaling axis involving integrin β1, c-Jun N-terminal kinase (JNK), and macrophage scavenger receptor 1 (MSR1), offering promising new targets for therapeutic intervention.

Polycystic ovary syndrome (PCOS) represents one of the most prevalent chronic endocrine-metabolic disorders affecting women of reproductive age, with global prevalence estimates ranging from 5% to 18%. Characterized by reproductive abnormalities, hormonal dysregulation, and metabolic dysfunction, PCOS constitutes a leading cause of female infertility and is frequently accompanied by insulin resistance, dyslipidemia, and obesity. Emerging evidence has increasingly implicated gut microbiota disturbances in PCOS pathogenesis, suggesting that probiotic interventions may offer novel therapeutic avenues. A research study investigated the therapeutic potential of Akkermansia muciniphila PROBIO (AP), a specific probiotic strain, in a dehydroepiandrosterone-induced PCOS rat model, revealing significant improvements in reproductive and metabolic parameters through modulation of gut microbiota and enhancement of arginine biosynthesis.

Protein S deficiency represents a rare but significant hereditary thrombophilia that poses substantial risks during pregnancy, yet clinical management remains controversial due to limited evidence-based guidance. A retrospective case-control study investigated the effects of low molecular weight heparin (LMWH) prophylaxis on pregnancy outcomes in women with suspected protein S deficiency, providing crucial insights into optimal anticoagulation strategies for this high-risk population. Conducted at Peking University People's Hospital between November 2012 and May 2024, the study analyzed 35 pregnant women with protein S activity levels indicating suspected deficiency, comparing 20 women who received LMWH prophylaxis with 15 who received standard care without anticoagulation, alongside 70 healthy pregnant controls.

Pelvic organ prolapse (POP) represents a highly prevalent condition among women, particularly following childbirth and during aging, with recurrence rates following surgical intervention posing significant clinical challenges that substantially increase treatment difficulty and healthcare burden. Despite advances in surgical techniques, the molecular mechanisms underlying POP recurrence remain poorly understood, limiting the development of targeted therapeutic strategies. A research study by Yaqian Li and colleagues employed single-cell RNA sequencing technology to conduct comprehensive comparative analysis of vaginal fibroblasts, smooth muscle cells, and macrophages between recurrent and primary POP patients, revealing substantial molecular heterogeneity that provides novel insights into the cellular and molecular drivers of POP recurrence.

Congenital heart defects (CHD) represent the most common congenital malformations globally and constitute a leading cause of neonatal mortality, with early maternal risk factors playing significant roles in their development. A comprehensive systematic review and meta-analysis by Zihan Suo and colleagues investigated the relationships between various maternal factors during the first trimester and the risk of CHD in offspring, providing robust evidence for public health strategies aimed at reducing CHD incidence. The study protocol was registered on PROSPERO (CRD42023476855), ensuring methodological transparency and rigor.
