Engineering Decavalent, Sperm‐Binding Laminin‐IgG Hybrid Antibodies for Potent Non‐Hormonal Contraception

open access: yesAdvanced Science, EarlyView.
This study investigates a highly multivalent mAb platform fusing Laminin‐511 heterotrimerization domains with Fabs and IgG1‐Fc as a non‐hormonal contraceptive. The most potent molecule ‘LamH10’, possessing 10 Fabs, rapidly achieved >99% reduction in progressively motile sperm at just 33µg per dose in sheep, making the laminin‐IgG hybrid platform the ...

Sex Hormone Binding Globulin Modifies Testosterone Action and Metabolism in Prostate Cancer Cells

open access: yesInternational Journal of Endocrinology, 2016
Sex Hormone Binding Globulin (SHBG) is the major serum carrier of sex hormones. However, growing evidence suggests that SHBG is internalised and plays a role in regulating intracellular hormone action.

Variation in circulating testosterone during mating predicts reproductive success in a wild songbird.

open access: yesFrontiers in Ecology and Evolution, 2016
Testosterone is an important sex hormone and mediates reproduction in male vertebrates. There is ample evidence that testosterone coordinates the expression of physiological, morphological and behavioural traits during reproduction and many of these ...

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

open access: yesAdvanced 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 ...

CO2‐DBU‐Triggered Photoredox‐Catalyzed Direct α‐C‐H Alkylation of Alcohols

open access: yesAdvanced Science, EarlyView.
An efficient photoinduced and metal‐free method is developed for direct α‐C–H monoalkylation of alcohols utilizing the CO2‐DBU system as the hydrogen bond acceptor (HBA) in the presence of H2O, allowing for selective functionalization of alcohols with a broad substrate scope.

Causal relationship between obesity and serum testosterone status in men: A bi-directional mendelian randomization analysis

open access: yesPLoS ONE, 2017
Context Obesity in men is associated with low serum testosterone and both are associated with several diseases and increased mortality. Objectives Examine the direction and causality of the relationship between body mass index (BMI) and serum ...

Sex-Specific Associations of Testosterone With Metabolic Traits

open access: yesFrontiers in Endocrinology, 2019
Background: Testosterone levels are differentially linked with diabetes risk in men and women: lower testosterone levels in men and higher testosterone levels in women are associated with type 2 diabetes, though, the mechanisms are not fully clear.

An association between adropin hormone and total testosterone in obese men: a case-control study

open access: yesBMC Endocrine Disorders, 2022
Background Obesity is associated with low testosterone levels that could be caused by many mechanisms. Adropin, a peptide hormone, its levels are decreased in obesity and its receptors are expressed in the hypothalamus, the pituitary gland, and the ...
