The dynamic chemical modifications of DNA, RNA, and proteins can transform normal cells into malignant ones. While the DNA and protein modifications in cancer have been described extensively in the literature, there are fewer reports about the role of RNA modifications in cancer. There are over 100 forms of RNA modifications and one of these, mRNA methylation, plays a critical role in the malignant properties of the cells. mRNA methylation is a reversible modification responsible for regulating protein expression at the post-transcriptional level. Despite being discovered in the 1970s, a complete understanding of the different proteins involved and the mechanism behind mRNA methylation remains largely unknown. However, these mRNA methylations have been shown to foster cancer hallmarks via specific cellular targets inside the cell. In this review, we provide a brief overview of mRNA methylation and its emerging role in regulating the various hallmarks of cancer.

Background: SET domain-containing protein 4 (SETD4) is a histone methyltransferase that has been shown to modulate cell proliferation, differentiation, and inflammatory responses by regulating histone H4 trimethylation (H4K20me3). Previous reports have demonstrated its function in the quiescence of cancer stem cells as well as drug resistance in several cancers. A limited number of systematic studies have examined SETD4's role in the tumor microenvironment, pathogenesis, prognosis, and therapeutic response.

RNA-specific nucleotidyltransferases (rNTrs) add nontemplated nucleotides to the 3 end of RNA. Two noncanonical rNTRs that are thought to be poly(A) polymerases (PAPs) have been identified in the mitochondria of trypanosomes - KPAP1 and KPAP2. KPAP1 is the primary polymerase that adds adenines (As) to trypanosome mitochondrial mRNA 3 tails, while KPAP2 is a non-essential putative polymerase whose role in the mitochondria is ambiguous.

Introduction And Aims: Oral squamous cell carcinoma (OSCC) is one of the most prevalent malignancy of the head and neck. Early diagnosis of OSCC is difficult and the prognosis has not improved significantly. This study aims to explore the role of tubulin polymerisation promoting protein 3 (TPPP3) in the occurrence and development of OSCC and discover new diagnostic and prognostic markers for OSCC.

N6-methyladenosine (m6A) is the most prevalent internal modification on mRNA and plays critical roles in various biological processes including virus infection. It has been shown that m6A methylation is able to regulate virus proliferation and host innate immunity in mammals and plants, however, this antiviral defense in insects is largely unknown. Here we investigated function of m6A and its associated methyltransferases in nucleopolyhedrovirus (BmNPV) infection in silkworm.

Objective: Asiaticoside has the capacity to induce osteogenic differentiation of human periodontal ligament cells (hPDLCs) through Wnt (Wingless-related integration site) signaling. A modified chemical structure (by removing glycoside side chain), referred to as asiatic acid methyl ester (AA1), has been constructed and evaluated for its capacity to induce osteogenic differentiation.
Design: hPDLCs viability was determined by MTT assay.
