Abstract

Insights

WTAP promotes colorectal cancer (CRC) growth and spread by increasing m6A modification of SNAI1. This study reveals WTAP as a potential oncogene in CRC, highlighting its role in cancer progression.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • N6-methyladenosine (m6A) modification is a key epigenetic regulator in cancer.
  • WTAP, an m6A RNA methyltransferase, is implicated in various cancers.
  • The specific role of WTAP in colorectal cancer (CRC) is not well understood.

Purpose of the Study:

  • To investigate the role and mechanism of WTAP in colorectal cancer (CRC).
  • To determine if WTAP functions as an oncogene in CRC progression.

Main Methods:

  • Compared WTAP expression in CRC and normal tissues using GEPIA.
  • Assessed WTAP's impact on CRC cell proliferation and migration via colony formation and transwell assays.
  • Investigated WTAP's role in m6A modification using RNA dot blot and MeRIP-PCR assays.

Main Results:

  • WTAP expression is significantly elevated in CRC tissues.
  • WTAP knockdown suppressed CRC cell proliferation and migration in vitro.
  • WTAP knockdown reduced m6A modification of SNAI1, inhibiting its expression.
  • Positive correlation observed between WTAP and SNAI1 expression in CRC.

Conclusions:

  • WTAP acts as an oncogene in colorectal cancer (CRC).
  • WTAP promotes CRC progression by regulating SNAI1 expression via m6A modification.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
