“…Till now, several modes of epigenetic regulation such as DNA methylation (hypomethylation and hypermethylation of gene promotor), histone modifications (methylation or acetylation etc.) (Zaguia et al, 2022), abnormal expression of microRNAs (miRNAs), long non-coding RNAs, and small nucleolar RNAs, have been discovered and documented (Ilm et al, 2016;Shanmugam et al, 2018). Moreover, important roles of each mode have been assessed in diverse pathological conditions (Jaenisch and Bird, 2003;Das and Singal, 2004;Kurdistani, 2007;Goel et al, 2017;Kashyap et al, 2018;Karir et al, 2020;Kashyap and Kaur, 2020).…”
