Specific JNK and p53 inhibitors stimulated the formation of fibroblast colonies (CFU-F) and clusters (ClFU-F) and increased proliferative activity of mesenchymal progenitor cells. No effects of inhibitors of JNK and p53 on differentiation of progenitor elements were revealed.

Psychopharmacological effects of JNK inhibitor were studied using a mouse model of posthypoxic encephalopathy. The preparation exhibited a pronounced cerebroprotective effect manifested in normalization of orientation and exploratory behavior and conditioned responses in posthypoxic mice. These effects were accompanied by marked elevation of neural stem cell content in the paraventricular region of the brain.

We examined 38 patients (mean age 55.92 ± 1.56 years) with a 3-5-year history of arterial hypertension. The study showed that hypertension is accompanied by endothelial dysfunction and one of its forming factors is activation of the inflammatory response. Highly sensitive diagnostic tests can verify initiation of inflammation in preclinical manifestations. The use of nonsteroidal anti-inflammatory drugs, irrespective of the tropism to cyclooxygenase forms, alleviates manifestations of endothelial dysfunction in patients with arterial hypertension.

We studied the psychopharmacological effects of atisine-type diterpene alkaloid Z77 in a rat model of cerebral ischemia. Pronounced cerebroprotective effect was found consisting in normalization of the orienting and exploratory activity and conditioned behavior associated with significant correction of morphological changes in the brain. The direct stimulatory effect of Z77 on neural stem cells was shown in vitro.

Psychopharmacological effects of atisine-type diterpene alkaloid Z77 were studied under conditions of experimental posthypoxic encephalopathy. The preparation had a pronounced cerebroprotective effect consisting in normalization of orientation and exploratory behavior and conditioned activity in experimental animals. These changes were accompanied by significant increase in the number of neural stem cells in the paraventricular region of the brain and markedly enhanced production of neurotrophic growth factors by neural tissue microenvironment cells.

We studied the in vitro role of NF-κB-dependent signaling in the growth capacity of mesenchymal progenitor cells upon stimulation by basic fibroblast growth factor. Proliferative activity of progenitor cells was suppressed by specifi c inhibitors of this transcription factor (NF-κB), oridonin and aurothiomalate. These inhibitors had no effect on differentiation of fibroblast CFU.
