 Targert Gene 
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> 5-methylcytidine (m5C)
Epigenetic Regulator 28S rRNA (cytosine-C(5))-methyltransferase (NSUN5) WRITER View Details
Regulated Target Phospholipid hydroperoxide glutathione peroxidase GPX4 (GPX4) View Details
Crosstalk Relationship m5C  →  m6A Enhancement
Crosstalk Mechanism RNA modification directly impacts m6A modification through recruiting m6A regulator and targeting the shared RNA
Crosstalk Summary RBM15B- and IGFBP2-mediated N6-methyladenosine (m6A) modification and NSUN5-mediated 5-methylcytosine (m5C) modification of Phospholipid hydroperoxide glutathione peroxidase GPX4 (GPX4) facilitated anticancer immunity via activation of cyclic GMP-AMP synthase (cGAS)-stimulator of interferon (STING) signaling by maintaining redox homeostasis in COAD.

In-vivo Model To develop the syngeneic model, 1 × 106 MC38-Ctrl or MC38-Gpx4KD cells were injected subcutaneously into the right flank of C57BL/6 mice, respectively. These two groups of mice were randomly and blindly allocated into separate groups 12 days after cell injection. Subsequently, either an anti-PD-1 antibody (5 mg/kg per mouse) or an IgG isotype was administered intraperitoneally every 2 days until the conclusion of the observation period.
