Article Abstract
Insulin resistance (IR) plays a critical role in cardiovascular diseases and metabolic diseases. In this study, we identified the downregulation of DMRT2 in adipose tissues from insulin-resistant subjects through bioinformatics analysis and in an insulin-resistant mouse model through experimental analysis. DMRT2 overexpression significantly attenuated HDF-induced insulin resistance and inflammation in mice. Moreover, in control and insulin-resistant differentiated mouse 3T3-L1 adipocytes, DMRT2 overexpression attenuated but DMRT2 knockdown enhanced the insulin resistance of 3T3-L1 adipocytes. DMRT2 interacted with FXR and positively regulated FXR level and transcription activity. In both control and insulin-resistant differentiated mouse 3T3-L1 adipocytes, FXR knockdown enhanced the insulin resistance and attenuated the effects of DMRT2 overexpression upon 3T3-L1 adipocyte insulin resistance. In conclusion, we identify the downregulation of DMRT2 in the insulin-resistant mouse model and cell model. DMRT2 interacts with FXR and improves insulin resistance in adipocytes.

Changes in antral follicle dynamics following weight loss in women with polycystic ovary syndrome.
Hum Reprod
September 2025
Division of Nutritional Sciences, Cornell University, Ithaca, NY, USA.
Study Question: Does weight loss from a hypocaloric dietary intervention improve antral follicle dynamics in women with PCOS?
Summary Answer: During a 3-month hypocaloric dietary intervention, women with PCOS who experienced clinically meaningful weight loss showed more organized antral follicle development including fewer recruitment events, but no change in the overall frequency of selection, dominance, or ovulation.
What Is Known Already: There is a spectrum of disordered antral follicle development in women with PCOS including excessive follicle recruitment and turnover, decreased frequency of selection and dominance, and failure of ovulation. Lifestyle intervention aimed at weight loss is recommended to improve metabolic health in women with PCOS yet benefits on ovarian follicle development and ovulation are unclear.
Hypoxia-induced impairments in fasting glucose are associated with acute mountain sickness severity during four days of residence at 4,300 m.

Unlabelled: Insulin resistance has been associated with acute mountain sickness (AMS) risk, but the influence of active ascent is unclear.
Methods: Thirty-two unacclimatized Soldiers (23±4yr; 80±14 kg) were tested at baseline residence (BLR), hiked ~5 km (n=16) or were driven (n=16) to 4,300 m, and stayed for 4 days (~66 h). Venous blood was taken each morning at BLR and during high altitude (HA) exposure days 2-4 (HA2-4) and the evening on day 1 at HA (HA1).
Over-time changes in the prevalence of metabolic syndrome and its components among elderly population in Iran from 2016 to 2021; A nation-wide study.

Background: The prevalence of Metabolic Syndrome (MetS) increases with aging, significantly contributing to the rising burden of non-communicable diseases (NCDs). This study aimed to investigate over-time changes in the prevalence of MetS and its components among the elderly population of Iran.
Methods: We analyzed data from the 2016 and 2021 national STEPwise approach to non-communicable disease risk factor Surveillance (STEPS) for participants aged ≥65 who completed all three survey steps (questionnaire-based assessments, physical measurements, and laboratory tests) with no missing data on MetS components.
Expression of long non-coding RNAs MALAT1, MEG3, and XIST in gestational diabetes mellitus: a cross-sectional study.

Background And Aims: Gestational diabetes mellitus (GDM) is defined as glucose intolerance first identified during pregnancy that does not meet the criteria for overt diabetes. Its pathophysiology shares key features with type 2 diabetes mellitus (T2D), including insulin resistance and inflammation. Emerging evidence suggests that long non-coding RNAs (lncRNAs) are implicated in T2D.

Purpose Of Review: Despite major advances in the treatment and prevention of atherosclerotic cardiovascular disease (ASCVD), a substantial burden of residual risk remains Obesity has been redefined as a primary and independent drivers of cardiovascular morbidity and mortality warranting focused attention.
Recent Findings: Obesity is now recognized as a chronic disease and a central contributor to residual cardiovascular risk through mechanisms including systemic inflammation, insulin resistance, dyslipidemia, and endothelial dysfunction. This review addresses the limitations of conventional obesity management and highlights emerging pharmacological therapies targeting the underlying adiposopathy.
