Papulocistic lesions of the face: the tip of the iceberg

Senses and Sciences, 2015
Acne is a manifestation of hormonal overstimulation of the pilosebaceous units of genetically susceptible individuals and may manifest in the form of comedonic, papulopustular or nodular lesions. It can present as an isolated disease or in the context of

Human P450 CYP17A1: Control of Substrate Preference by Asparagine 202 [PDF]

, 2018
CYP17A1 is a key steroidogenic enzyme known to conduct several distinct chemical transformations on multiple substrates. In its hydroxylase activity, this enzyme adds a hydroxyl group at the 17α position of both pregnenolone and progesterone at ...

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

MUTATIONAL SPECTRUM OF THE STEROID 21-HYDROXYLASE GENE [PDF]

Pediatric Research, 1993
Lesions in the gene encoding steroid 21-hydroxylase (CYP21) result in defective adrenal steroid synthesis; the severe forms are known as congenital adrenal hyperplasia. To facilitate.complete characterization of mutations in this region of landemly repeated genes, we have developed selective PCR amplification and direct sequencing of full-length ...

Porcine kidney xenotransplantation: From primate models to clinical reality

Animal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Localization of sterols and oxysterols in mouse brain reveals distinct spatial cholesterol metabolism [PDF]

, 2020
Dysregulated cholesterol metabolism is implicated in a number of neurological disorders. Many sterols, including cholesterol and its precursors and metabolites, are biologically active and important for proper brain function. However, spatial cholesterol

Determination of functional effects of mutations in the steroid 21-hydroxylase gene (CYP21) using recombinant vaccinia virus.

Journal of Biological Chemistry, 1990
Steroid 21-hydroxylase (P450c21) is absent or defective in more than 90% of patients with congenital adrenal hyperplasia. This disorder of cortisol biosynthesis occurs in a wide spectrum of clinical severity; specific mutations in the 21-hydroxylase gene

Insulin Resistance: An Update on Biochemical and Pathophysiological Mechanisms and Impact on Various Diseases

iNew Medicine, EarlyView.
ABSTRACT Insulin resistance is the biological phenomenon in which the human body's normal response to the metabolic hormone insulin is compromised. Insulin is a regulator of most of the essential metabolic steps in the body that control energy homoeostasis, so dysregulation leads to multiple diverse human diseases including, most prominently, Type 2 ...

A Neonate Presenting with Severe Dehydration - A Case of Congenital Adrenal Hyperplasia with Salt Losing Crisis

Journal of Nepal Medical Association
Congenital adrenal hyperplasia (CAH) is a rare autosomal recessive disorder caused by mutations in genes involved in cortisol biosynthesis in the adrenal gland. Depending on the enzymatic defect, the symptoms, signs, and laboratory findings differ.
