Protein kinase C(PKC) is a kind of kinase which is widely involved in cell proliferation and development. PKC(Wp-PKC) in Whitmania pigra body belongs to classic PKC. In order to investigate the effect of Wp-PKC on the development of Wh. pigra germ cells, 17β-estradiol(17β-E2)(100 ng·mL~(-1)) and methyltestosterone(MT)(150 μg·L~(-1)), 150 μg·L~(-1)(MT)+0.5 mg·L~(-1) PKC, 0.5 mg·L~(-1) PKC inhibitor were added to Wh. pigra culture water, and no addition group(control group) was added, and the effects on the development of Wh. pigra germ cells and the expression of Wp-PKC were observed. The results showed that: Wp-PKC in male gonads was always higher than that in female gonads; MT promoted the development of male gonads in Wh. pigra, while the expression of Wp-PKC was significantly higher than that in the control; 17β-E2 promoted the development of female gonads in Wh. pigra and Wp-PKC expression significantly lower than that of the control; while the development of the female and male gonads in the PKC inhibitor group was inhibited, the expression of Wp-PKC was significantly lower than that of the control. In summary, Wp-PKC may promote the development of Wh. pigra, especially the development of male gonads.

Transcriptional regulation of the piRNA pathway by Ovo in animal ovarian germ cells.

The gene-regulatory mechanisms controlling the expression of the germline PIWI-interacting RNA (piRNA) pathway components within the gonads of metazoan species remain largely unexplored. In contrast to the male germline piRNA pathway, which in mice is known to be activated by the testis-specific transcription factor A-MYB, the nature of the ovary-specific gene-regulatory network driving the female germline piRNA pathway remains a mystery. Here, using as a model, we combined multiple genomics approaches to reveal the transcription factor Ovo as regulator of the germline piRNA pathway in ovarian germ cells.

Hormonal factors play an essential role as an underlying causative factor of oligoasthenoteratozoospermia (OAT), and these patients can benefit from hormonal medications that modulate the hypothalamic-pituitary-gonadal axis. This review aims to outline the various medications used as hormonal therapy in treating infertile men with OAT. This manuscript focuses on essential hormonal evaluation, identifying men who would benefit from treatment, selecting the appropriate medication, determining the duration of therapy, and evaluating hormonal treatment outcomes.

While ultraviolet C (UVC) radiation has beneficial applications, it can also pose risks to living organisms. Nevertheless, a detailed assessment of UVC radiation's effects on mammalian male reproductive physiology, including the underlying mechanisms and potential protective strategies, has not yet been accomplished. This study aimed to examine the critical roles of oxidative stress, autophagy, reproductive hormonal axis, and microRNAs in UVC-induced reproductive challenges in male rats.

During all periods of male ontogenesis, physiological processes responsible for the correct functioning of reproductive organs and spermatogenesis are under the influence of various factors (neuro-humoral, genetic, and paratypical). Recently, the attention of researchers has increasingly turned to the study of epigenetic factors. In scientific publications, one can increasingly find references to the direct role of microRNAs, small non-coding RNAs involved in post-transcriptional regulation of gene expression, in the processes of development and functioning of reproductive organs.

Background: Cryptorchidism is the absence of one or both testicles in the scrotum at birth, being a risk factor for testis cancer and infertility. The most effective method to treat cryptorchidism is orchiopexy, followed by human chorionic gonadotropin (hCG) therapy; however, a portion of treated patients do not show a significant improvement in testis volume and vascularization after adjuvant therapy.
Methods: In this study, we generated an in vitro model to predict the patient response to hCG by cultivating and treating primary cells derived from five cryptorchid patients' biopsies of gubernaculum testis, the ligament that connects the testicle to the scrotum.
