Indole-3-carbinol and its main derivative 3,3'-diindolylmethane: Regulatory roles and therapeutic potential in liver diseases.

Indole-3-carbinol (I3C), a compound found in cruciferous vegetables, has shown significant efficacy in treating both cancerous and non-cancerous diseases. Its primary derivative, 3,3'-diindolylmethane (DIM), formed during digestion, also exhibits similar therapeutic benefits. In liver disorders, I3C and DIM exhibit dual roles by inhibiting and promoting hepatocellular carcinoma (HCC) and providing relief for nonmalignant liver diseases, such as acute liver injury (ALI), hepatic fibrosis, nonalcoholic fatty liver disease (NAFLD), and alcohol-related liver disease (ALD).

Immune Gene Signatures and Immunotypes in Immune Microenvironment Are Associated With Glioma Prognose.

Glioma is the most common primary malignant brain tumor in adults with very poor prognosis. The limited new therapeutic strategies for glioma patients can be partially attributed to the complex tumor microenvironment. However, knowledge about the glioma immune microenvironment and the associated regulatory mechanisms is still lacking.

Animal models in sexual dysfunction were reviewed to further improve the modeling methods and to promote the effectiveness of drug evaluation translation from animal models to humans. A MEDLINE search was performed to retrieve articles relating to animal models in sexual dysfunction. Researches on a variety of animal models in sexual dysfunction, with their own merits, has to a certain extent contributed to the understanding of sexual function.

[Androgen regulates penile erection at the peripheral level].

Androgen has been claimed for so long as a pivotal hormone in regulating male sexual function, acting both at the central and peripheral level. We believe that androgen is indeed the main synchronizer of sexual activity regulating libido and enzymes as nitric oxide synthase (NOS) and phosphodiesterase type 5 ( PDE5) , which are crucial for the erectile process. The main action of androgen is to timely adjust the erectile process as a function manifestation of sexual desire, therefore finalizing erection to sex.
