Abstract:
The cells of buccal epithelium were investigated in groups of smoking and non-smoking students. Cell samples were collected by scraping with blunt sterile spatula, stained with orcein and photographed. The smoking of cigarettes and hookah induces significant decrease in nuclear and cell perimeter and cell area in cells of buccal epithelium. Smoking of hookah induces, besides, the heterochromatization in cell nuclei and the decrease of nuclear area. The data obtained indicate stress reaction in cells (heterochromatinization) and apoptosis-related changes in cells (decrease of nuclear and cell perimeter and cell area). These data show unfavorable effects of smoking cigarettes and even more harmful effect of hookah smoking.

Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...
