However, the ageing mechanism of various kinds of stem cells, such as SLCs in the reproductive system, remains unknown. Multiple organs in the reproductive system display particularly high steroidogenesis activity due to the production of sex hormones. In the testis, the production of testosterone ...

perhaps involving activity-dependent NTF/RTK signaling. This mechanism would allow resting secretory terminals to accumulate neurohormones to levels sufficient for sustaining endocrine signaling, and maintain the system in an energetically favorable ‘primed-but-off’ state that would decouple neurohormone ...
In plants, enzymes of this family catalyze the formation of the plant hormone ethylene by oxidative desaturation of 1-aminocyclopropane-1-carboxylate, and catalyze the hydroxylation and desaturation steps in the synthesis of other plant hormones, pigments and metabolites such as gibberellins, ...
in various cell types.26Hence, we screened a panel of drugs, hormones and pathogens for their ability to transactivate latent HHV-6 using our in vitro U2OS latent HHV-6 cells carrying either a RFP or a GFP reporter. For this purpose, cells were seeded in 6-well cell culture plates and ...
In summary, three human studies support the concept that the metabolic environment in male prepuberty might influence the respiratory health of offspring, and the role of the exogenous sex hormones before conception cannot be disregarded. Although extensive for some other outcomes, animal studies on ...
