Abstract
The definitive number of Sertoli cells (SCs), achieved during the proliferative periods, defines the spermatogenic capacity in adulthood. It is recognized that FSH is the main mitogen targeting SC and that it exerts its action, at least partly, through the activation of the PI3K/Akt/mTORC1 pathway. mTORC1 controls a large number of cellular functions, including glycolysis and cell proliferation. Interestingly, recent evidence revealed that the glycolytic flux might modulate mTORC1 activity and, consequently, cell cycle progression. Although mature SC metabolism has been thoroughly studied, several aspects of metabolism regulation in proliferating SC are still to be elucidated. The objective of this study was to explore whether aerobic glycolysis is regulated by FSH through mTORC1 pathway in proliferating SC, and to assess the involvement of glycolysis in the regulation of SC proliferation. The present study was carried out utilizing 8-day-old rat SC cultures. The results obtained show that FSH enhances glycolytic flux through the induction of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3 (PFKFB3) and lactate dehydrogenase A (LDHA) in an mTORC1 dependent manner. In addition, PFKFB3 and LDH inhibitors prevent FSH from activating mTORC1 and stimulating SC proliferation and glycolysis, presumably through mTORC1 pathway inhibition. In summary, FSH simultaneously regulates SC proliferation and glycolysis in an mTORC1 dependent manner, and glycolysis seems to cooperate with FSH in the stimulation of both cellular functions through the modulation of the same signalling pathway. Therefore, a positive feedback between the mTORC1 pathway and glycolysis triggered by FSH is hypothesized.

Abstract
Sertoli cells provide structural and nutritional support for germ cell development. They actively metabolize glucose and convert it into lactate, which is an important source of energy for germ cells. They also oxidize fatty acids (FA), stored as triacylglycerides (TAGs) within lipid droplets (LD), to fulfill their own energy requirements. So, the combined regulation of lactate production and FA metabolism may be relevant to the physiology of seminiferous tubules. Resveratrol (RSV) is a nutritional supplement found primarily in red grape skin that exhibits multiple beneficial health effects: it is cardioprotective, anti-inflammatory, anticancer, and antiaging. The aim of this study was to evaluate the effect of RSV in Sertoli cells lactate production and lipid metabolism. Sertoli cell cultures obtained from 20-day-old rats were incubated for different times with 10 or 50 μM RSV. RSV treatment increased lactate production and glucose consumption. These increments were accompanied by a rise in GLUT1 expression, which is the main glucose transporter in Sertoli cells. On the other hand, RSV decreased LD content and TAG levels. In addition, an increase in ATGL and FAT/CD36 mRNA levels was observed, which suggests augmented cytoplasmatic FA availability. RSV treatment also increased P-ACC levels, which might indicate that RSV promotes FA transport into the mitochondria to be oxidized. An enhanced expression of LCAD and MCAD, enzymes that participate in the oxidation of FA, was also observed. Altogether, these results suggest that RSV simultaneously regulates Sertoli cells lactate production and lipid metabolism, ensuring an adequate energetic balance both in germ and Sertoli cells.
