Nandrolone is a testosterone analogue with anabolic properties commonly abused worldwide, recently utilized also as therapeutic agent in chronic diseases, cancer included. Here we investigated the impact of nandrolone on the metabolic phenotype in HepG2 cell line. The results attained show that pharmacological dosage of nandrolone, slowing cell growth, repressed mitochondrial respiration, inhibited the respiratory chain complexes I and III and enhanced mitochondrial reactive oxygen species (ROS) production. Intriguingly, nandrolone caused a significant increase of stemness-markers in both 2D and 3D cultures, which resulted to be CxIII-ROS dependent. Notably, nandrolone negatively affected differentiation both in healthy hematopoietic and mesenchymal stem cells. Finally, nandrolone administration in mice confirmed the up-regulation of stemness-markers in liver, spleen and kidney. Our observations show, for the first time, that chronic administration of nandrolone, favoring maintenance of stem cells in different tissues would represent a precondition that, in addition to multiple hits, might enhance risk of carcinogenesis raising warnings about its abuse and therapeutic utilization.

Cytochrome P450 enzymes (CYPs) are versatile biocatalysts involved in the biosynthesis, activation, and detoxification of a wide range of endogenous and exogenous compounds. While the CYP107 family is primarily associated with macrolide antibiotic biosynthesis, some members, such as OleP (CYP107D1) and CYP107X1, have also been shown to catalyze steroid hydroxylation, albeit with limited substrate scope. In this study, we identified CYP107E41 from Streptoalloteichus sp.

This case report highlights the importance of meticulous monitoring of all medications and dietary supplements used by solid organ transplant recipients. Although the recommended daily allowances of vitamins, minerals, and herbs are generally considered safe, combining various supplement formulations can result in excessive intake, thereby increasing the risk of allograft injury in this patient population.

The term ``anabolic-androgenic steroids'' (AASs) refers to a class of artificial substances that resemble the natural testosterone. The most often misused androgen, nandrolone decanoate (ND), is regarded as a public health concern that needs immediate action to raise public awareness of toxicology results on AAS usage. This study designed to investigate the therapeutics effect of nano ferrite-chitosan-curcumin nanoparticles (NF-CH-CurNPs) against ND induced renal toxicity, proliferation, inflammation, and oxidative stress in male rats.

Nandrolone decanoate, a synthetic form of the testosterone hormone, is misused by some bodybuilders and adolescents to gain muscle mass. We investigated its effect on the prostate during postpubertal age and evaluated the reversibility of these effects after a period of cessation. Thirty albino rats were utilized and categorized into three distinct groups: Control group, a treated group that received nandrolone decanoate weekly by intramuscular injection with 10 mg/kg for 4 weeks while recovery group received nandrolone, similar to the treated group, followed by an additional recovery period of 4 weeks.

Objective: We aimed to assess the effects of contraception with NuvaRing on ultrasound signs and symptoms of women with adenomyosis.
Study Design: We conducted a prospective self-controlled observational study on women with adenomyosis who required contraception with NuvaRing. Exclusion criteria were actual use or contraindications to hormonal contraception.
