OBJECTIVE: Fasting is an activity that requires a certain calorie restriction without consuming food or drinks for a certain period of daytime. However, fasting triggers many complex events, including activating cellular stress response pathways, autophagy promotion, apoptosis pathways, and a change in hormonal balance. Among the many events affecting the regulation of apoptosis, the expression of microRNAs (miRNAs) plays an important role. Therefore, we aimed to investigate the levels and importance of miRNA expression in fasting.

PATIENTS AND METHODS: The expressions of 19 miRNAs regulating different pathways from saliva samples, isolated by matching healthy university students (n = 34) as group 1 (fasting for 17 consecutive hours) and group 2 (testing 70 minutes after meal consumption), were examined using the real-time PCR method.

RESULTS: In fasting, modulation of apoptotic pathways by miRNAs triggers anti-pathogenic effects, and the adaptation of abnormal cells in the body decreases. For this reason, vital diseases, such as cancer, can be treated by preventing the proliferation and growth of cancerous cells by increasing programmed cell death due to the downregulation expression mechanism of miRNAs.

CONCLUSIONS: Our study aims to improve the knowledge about the mechanisms and functions of miRNAs in various apoptosis pathways during fasting and may be a model for further future physiological and pathological studies.
