Acne vulgaris is the most common skin disorder and contributes an estimated 0.29% of the global burden of disease. The pathophysiology of acne involves excess sebum production and altered lipid composition by the sebaceous glands, follicular hyperkeratinization, bacterial colonization by Cutibacterium acnes (C. acnes), and perifollicular inflammation. 13-cis Retinoic Acid (13-cis RA), also known as isotretinoin, is the only acne therapy that targets all four pathologic mechanisms and is often prescribed to patients with severe acne.

Acid exposure induces expression of certain metabolites in bacteria. The experimental objective was to identify the primary metabolites accumulating in E.coli O26:H11 as a function of acid (pH 3.6) ex...
Vitamin A deficient females have reduced fertility due to decreased retinoic acid production. WIN 18,446 inhibits retinoic acid biosynthesis and functions as a contraceptive in males. We tested whethe...
The vitamin A derivative 9-cis-retinoic acid (9-cis-RA) has been used for the treatment and prevention of cutaneous T-cell lymphoma (CTCL). However, the precise mechanism by which 9-cis-RA treatment a...
Activation of Toll-like receptor (TLR)-2 and subsequent inflammatory response contribute to lesion development in acne vulgaris. A cross-talk between aryl hydrocarbon receptor (AhR), a cytosolic recep...
Severe and persistent haze accompanied by high concentrations of fine particulate matter (PM) has become a great public health concern in urban China. However, research on the health effects of PM in ...
This is a dosage escalation study to estimate the maximum tolerated dose of 9-cis-retinoic acid given in combination with tamoxifen. Groups of 3 to 6 patients receive oral 9-cis-retinoic ...
Men with infertility and normal hormone levels have few options for fertility treatment. Previous research suggests that men with infertility may have low levels of the active form of Vita...

The goal of this clinical research study is to find the highest safe dose of the drug ZactimaTM (ZD6474) in patients with neuroblastoma or medulloblastoma that has gotten worse, has come b...
This study is being conducted in order to determine the safety, dose-limiting toxicities, and maximum tolerated dose of cabozantinib in combination with 13-cis-retinoic acid in patients wi...
Proteins in the nucleus or cytoplasm that specifically bind RETINOIC ACID or RETINOL and trigger changes in the behavior of cells. Retinoic acid receptors, like steroid receptors, are ligand-activated transcription regulators. Several types have been recognized.
A cytochrome P450 enzyme that resides in the ENDOPLASMIC RETICULUM. It catalyzes the conversion of trans-RETINOIC ACID to 4-hydroxyretinoic acid.
A subtype of RETINOIC ACID RECEPTORS that are specific for 9-cis-retinoic acid which function as nuclear TRANSCRIPTION FACTORS that regulate multiple signalling pathways.
Standards for limiting worker exposure to airborne contaminants. They are the maximum concentration in air at which it is believed that a particular substance will not produce adverse health effects with repeated daily exposure. It can be a time-weighted average (TLV-TWA), a short-term value (TLV-STEL), or an instantaneous value (TLV-Ceiling). They are expressed either as parts per million (ppm) or milligram per cubic meter (mg/m3).
A cytochrome P450 enzyme family whose members function in the metabolism of RETINOIC ACID. It includes RETINOIC ACID 4-HYDROXYLASE.
Acne is a common skin condition that causes spots to develop on the skin, usually on the face, back and chest.. The spots can range from blackheads and whiteheads which are often mild, to inflamed pus-filled pustules and cysts, which can be severe ...
