• Cellular and molecular events and signaling pathways involved in adaptive response of stressed organism.

• Effects of acute and chronic in vivo treatments with sildenafil (Viagra®, medicine for erectile dysfunction and pulmonary hypertension) on function and signaling of Leydig cells and spermatozoa.

• Regulation of homeostasis and signalization of Leydig cells and spermatozoa during aging.

• Circadian function of Leydig cells of adults and during aging.

• Role of LH, glucocorticoids and melatonin as a synchronizer of peripheral biological clock in Leydig cells.

• Role of Leydig cells’ androgen receptors in molecular adaptation during disturbed homeostasis.

• Role of IGF1R/INSR in regulation of mitochondrial biogenesis and testosterone biosynthesis in Leydig cells.

• Regulatory mechanisms of mitochondrial biogenesis in cells of reproductive axis of male and female.

• Molecular markers of mitochondrial biogenesis in different organs (pineal gland, hypothalamus, brain, adenohypophysis, neurohypophysis, heart, liver, white and brown adipose tissue, kidneys, adrenal glands, testes, prostates, ovaries, musculus gastrocnemius, musculus soleus) from normal and animals with disturbed homeostasis.

• Molecular markers of mitochondrial biogenesis and functionality of spermatozoa during disturbed homeostasis.

• Effects of chronic application of metformin (Glucophage®; medicine for diabetes type 2 and insulin resistance) on function and regulation of Leydig cells, spermatozoa, as well as cells of hypothalamus and adenohypophysis from adult, middle aged and old rats.
