You will read the transcript of discussions that actually took place at the Endocrinology Unit in Modena, Italy, in the form of the aporetic dialogues of ancient Greece. In this episode, the role of testosterone in gender differences in criminal behavior will be explored. The discussants were divided into two groups: group 1, which supports the thesis of a predominant role of testosterone, and group 2, which opposes it. The first group affirmed that both endogenous testosterone and anabolic-androgenic steroids could trigger aggressive and criminal behavior, regardless of predisposition to psychiatric disease or sociocultural background. The second group asserted the multifactorial genesis of aggressive and criminal behavior, citing other hormonal and non-hormonal factors, such as neurotransmitters, cortisol, and sociological and psychological aspects.

Activation of GR by dexamethasone (Dex) strongly influences the phenotype of cultured human testicular peritubular cells (HTPCs), causing massive changes of their proteome and secretome. As glucocorticoids (GC) are also known to set the internal clock of peripheral organs by regulating clock genes, we tested such an influence of Dex in HTPCs.</p><p><strong>Methods: </strong>We performed cellular studies with HTPCs and immortalized nonhuman primate (Callithrix jacchus; Cj)-derived peritubular cells, organotypic incubations of testicular fragments of Cj, qPCR and proteomic, as well as immunohistochemical studies.</p><p><strong>Results: </strong>Basal clock gene expression levels, when monitored by qPCR under standard culture conditions, showed alterations over 24 h, suggesting an endogenous circadian rhythm, especially for BMAL1. Dex (1 µM) when added to cells, caused a strong and significant increase of PER1, followed by elevations of BMAL1, and other clock genes. This action was observed as early as 4 h after the addition of Dex. Immunohistochemistry and data mining revealed GR in testicular peritubular cells and other somatic cells of Cj, in situ. We therefore performed organotypic incubations of testicular fragments of Cj (n = 3) and found that upon addition of Dex (1 µM), mRNA levels of BMAL1 and PER1 also increased in samples of two out of three animals after 6 h. Mass spectrometry did, however, not reveal significant alterations of the testicular proteome, possibly due to the short time point and/or the fact that the somatic GR-expressing cells represent only a small portion of the testis. In support for this assumption, Dex (1 µM; 6 h) significantly increased mRNA levels of BMAL1 and PER1 in Cj-derived immortalized testicular peritubular cells.</p><p><strong>Conclusion: </strong>The results indicate that an internal clock system likely exists in peritubular cells of the testis and that Dex, via testicular GR expressed by peritubular cells and other somatic cells, is a strong regulator of this system.
