Comprehensive RNA-seq analysis of benign prostatic hyperplasia (BPH) in rats exposed to testosterone and estradiol.

The imbalance between estrogen and androgen may be an important mechanism of BPH, but the specific mechanism remains unclear. We used mixed sustained-release pellets made of testosterone and estradiol (T + E) to stimulate the establishment of a BPH rat model. Compared to the prostate hyperplasia rat model using only androgens, the new prostate hyperplasia rat model can be observed to have better macroscopic and pathological characteristics of prostate hyperplasia.

Malignant melanoma represents the fifth most common cancer in the world and its incidence is rising. Novel therapies targeting receptor tyrosine kinases, kinases and immune checkpoints have been employed with a significant improvement of the overall survival and long-term disease containment. Nevertheless, the disease often progresses and becomes resistant to the therapies.

Esophageal cancer is a grave malignant condition. While radiotherapy, often in conjunction with chemotherapy, serves as a cornerstone in the management of locally advanced or metastatic cases, patient tolerance and treatment resistance frequently hinder its efficacy. Cell-in-cell structures, prevalent in various tumors, have been linked to prognosis.

Benign prostatic hyperplasia (BPH) is a health issue caused by an enlarged prostate in older men. Its prevalence increases with age, and it results in urination-related problems. This works studied the effect of purple corn extract (PCE) on improving BPH symptoms using a testosterone propionate (TP)-induced rat model.

Existing treatments for androgenetic alopecia (AGA) are unsatisfactory, owing to the two major reasons: (1) Oxidative stress and vascularization deficiency in the perifollicular environment provoke the premature senescence of hair follicles, limiting transformation from the telogen to the anagen phase; (2) The amount of drug delivered to the perifollicular region located in the deep dermis is very limited for passive drug delivery systems. Herein, we developed a gas-propelledmicroneedle patch integrated with ferrum-chelated puerarin/quercetin nanoparticles (PQFN) to increase drug accumulation in hair follicles and reshape the perifollicular environment for improved hair-regenerating effects. PQFN can rejuvenate testosterone (Tes)-induced senescence of dermal papilla cells by scavenging ROS, restoring mitochondrial function, regulating signaling pathways related to hair regeneration, and upregulating hair growth-promoting genes.
