Exosomes From Intestinal Epithelial Cells Promote Hepatic Differentiation of Liver Progenitor Cells in Gut‐Liver‐on‐a‐Chip Models

Advanced Science, EarlyView.
The effects of intestinal epithelial cells and their exosomes on the hepatic differentiation of HPCs are explored in a gut‐liver‐on‐a‐chip. Exosomes from intestinal epithelial cells improve liver fibrosis. Moreover, the miR‐371‐373 cluster in the exosomes may mediate this effect by regulating the hepatic differentiation of HPCs.

A Super‐Enhancer‐Driven Transcriptional Regulatory Circuit Underlying Abiraterone Resistance in Castration‐Resistant Prostate Cancer

Advanced Science, EarlyView.
This study identifies a super‐enhancer‐driven transcriptional regulatory circuit comprising BCL6, SMAD3, and NFIB that cooperate to drive cholesterol synthesis via SREBF2/HMGCR/FDFT1 activation and regulate CDK2/CCND3 for cell cycle control. Targeting this circuit with BI‐3802 or downstream inhibitors (Fatostatin/Lovastatin) overcomes abiraterone ...

Oral Engineered Extracellular Vesicles Based on Ion Exchange Strategy for Multipronged Management of Wilson's Disease Complicated with Reproductive Dysfunction Therapy

Advanced Science, EarlyView.
This study reports for the first time an oral targeted nanomedicine that conducts ion exchange through engineered Ganoderma‐derived extracellular vesicle, managing both the in‐copper and ex‐copper in a multi‐pronged approach, offering a promising therapeutic strategy for addressing WD with reproductive dysfunction.

A Novel Cultivation System for Germ Cell Proliferation and Sustaining Whole Testicular Niche

Advanced Science, EarlyView.
A hydrogel microneedle‐based system enables whole testicular cultivation, supporting spermatogonial proliferation and enhancing spermatogenesis in vitro. This ‘whole testicular spermatogonia pool’ (WTSP) significantly increases spermatid production and fertility potential in mice. This system also promotes spermatogonial expansion in human fetal testes,

Application of Transdermal Testosterone in Treatment of Male Hypogonadism

Journal of Mazandaran University of Medical Sciences, 2018
Testosterone is one of the most important male steroid hormones that plays a key role in the development of male reproductive tissues. The secretion of this hormone decreases rapidly after age 50. Hypogonadism in men is a clinical syndrome that is caused

Testosterone patch improves ovarian follicular response to gonadotrophins in a patient with Kallmann's syndrome: A Case Report [PDF]

Human Reproduction, 2007
Achieving ovulation in women with Kallmann's syndrome requires both exogenous FSH and LH to successfully stimulate follicular maturation and ovarian steroidogenesis. We present a case of a woman with Kallmann's syndrome, who had poor ovarian response to stimulation by exogenous gonadotrophins.

Therapeutic Repair of Sperm Quality Decline Caused by Polytetrafluoroethylene

Advanced Science, EarlyView.
Exposure to PTFE (teflon), a commonly used microplastic in non‐stick cookware, significantly reduces sperm quality in both humans and mice. Specifically, PTFE induces the disruption of sperm cytoskeleton and F‐actin assembly through targeting SKAP2 in haploid spermatid.

LncRNA Foxo6os as a Novel “ Scaffold” Mediates MYBPC3 in Combating Pathological Cardiac Hypertrophy and Heart Failure

Advanced Science, EarlyView.
Schematic overview showing that forkhead box O6, opposite strand (Foxo6os) acts as a “scaffold”, directly binding myosin‐binding protein‐C (MYBPC3) and recruiting protein kinase C (PKC‐α) to mediate site‐specific phosphorylation of MYBPC3. This post‐translational modification supports cardiac contraction by regulating L‐type Ca2+ channels, especially ...
