Abstract Mature males of a wild boar-pig crossbreed during long- and short-day seasons were used for the study, which demonstrated that the chemical light carrier CO regulates the expression of biological clock genes in the hypothalamus (preoptic area - POA and dorsal part of hypothalamus - DH) via humoral pathways. Autologous blood with experimentally elevated concentrations of endogenous CO (using lamps with white light-emitting diodes) was infused into the ophthalmic venous sinus via the right dorsal nasal vein.The results showed that elevated endogenous CO levels through blood irradiation induced changes in gene expression involved in the functioning of the main biological clock. Changes in the expression of the transcription factors Bmal1, Clock and Npas2 had a similar pattern in both structures, where a very large decrease in gene expression was shown after exposure to elevated endogenous CO levels. The changes in the gene expression of PER 1-2, CRY 1-2, REV-ERB α-β and ROR β are not the same for both POA and DH hypothalamic structures, indicating that both structures respond differently to the received humoral signal.The obtained results indicate that CO is a chemical light molecule whose production in organisms depends on the amount of light. An adequate amount of light is an essential factor for the proper functioning of the main biological clock.
