Steroid hormone receptors are key mediators in the execution of hormone action through a combination of genomic and non-genomic action. Since their isolation and characterisation in the early 20th Century much of our understanding of the biological actions of steroid hormones are underpinned by their activated receptor activity. Over the past two decades there has been an acceleration of more omics-based research which has resulted in a major uptick in our comprehension of genomic steroid action. However, it is well understood that steroid hormones can induce very rapid signalling events in tandem with their genomic actions wherein they exert their influence through alterations in gene expression. Thus the totality of genomic and non-genomic steroid action occurs in a simultaneous and reciprocal manner and a greater appreciation of whole cell action is required to fully evaluate steroid hormone activity in vivo. In this mini-review we outline the most recent developments in non-genomic steroid action and cytoplasmic steroid hormone receptor biology in endocrine-related cancers with a focus on the 3-keto steroid receptors, in particular the androgen receptor.

This Therapeutic Letter considers the evidence for inhaled corticosteroids (ICS) as a treatment for Chronic Obstructive Pulmonary Disease (COPD). Drug therapy aims to alleviate symptoms, enhance functional capacity and prevent exacerbations, but has not consistently shown to reduce mortality or improve quality of life based on randomised trials.Inhaled corticosteroids have shown limited benefits for COPD symptoms and exacerbations but increased risks of serious harms.

Introduction Congenital adrenal hyperplasia (CAH) is an autosomal recessive disorder primarily caused by 21-hydroxylase enzyme deficiency, impairing cortisol synthesis and resulting in elevated androgen levels. CAH presents in two classical forms: salt-wasting (SW) and simple virilizing (SV). Although CAH is rare in India, regional variations and the absence of a national newborn screening (NBS) program pose significant challenges to accurate diagnosis.

Background: The normal development of the liver during human embryonic stages is critical for the functionality of the adult liver. Despite this, the essential genes, biological processes, and signal pathways that drive liver development in human embryos remain poorly understood.
Methods: In this study, liver samples were collected from human embryos at progressive developmental stages, ranging from 2-month-old to 7-month-old.

Sensitive and precise assay of prednisolone, a steroid hormone, has received great attention due to its significant role in the treatment of a series of diseases. In this study, we have developed a simple, quick, and accurate technique in this part to measure prednisolone. Cobalt 5,10,15,20-tetra(4-pyridyl)-21H,23H-porphine (CoTPyP) as a mimic peroxidase catalyzes the chemiluminescence (CL) reaction of lucigenin for the first time.

The twin testosterone transfer (TTT) hypothesis posits that females with male co-twins (opposite-sex, OS) might develop male-typical traits due to higher prenatal testosterone exposure. This study explored whether females of OS have lower 2D:4D digit ratios and higher testosterone levels compared to females of same-sex (SS) twin pairs. Conducted in Tamale from January to December 2022, the study included 40 participants aged 18-27 years: 10 males of OS, 10 females of OS, and 20 females of SS twin pairs.
