Insights

Human beta-defensin 1 (HBD-1) may influence colorectal cancer (CRC) development and progression. This review explores HBD-1

Area of Science:

  • Oncology
  • Microbiology
  • Molecular Biology

Background:

  • Colorectal cancer (CRC) incidence is rising, especially in younger adults, suggesting links to diet and gut microbiome.
  • The PI3K/AKT/mTOR pathway is a key regulator of cell growth and a potential therapeutic target in CRC.
  • Defensins, like human beta-defensin 1 (HBD-1), possess antimicrobial properties and may play a role in CRC.

Purpose of the Study:

  • To review recent advances in understanding how HBD-1 influences CRC initiation and progression.
  • To highlight the molecular mechanisms by which HBD-1 impacts CRC.
  • To describe the interaction between defensins and the mTOR pathway in CRC.

Main Methods:

  • Literature review of recent studies on HBD-1 and CRC.
  • Analysis of molecular mechanisms linking HBD-1 to CRC.
  • Examination of the interplay between defensins and the mTOR pathway in colorectal cancer.

Main Results:

  • HBD-1's role in CRC initiation and progression is increasingly recognized.
  • Specific molecular mechanisms of HBD-1's impact on CRC are being elucidated.
  • Interactions between defensins and the mTOR pathway are crucial in CRC development.

Conclusions:

  • Understanding HBD-1's function in CRC offers potential for improved diagnostics and therapies.
  • Targeting HBD-1 and the mTOR pathway may represent novel therapeutic strategies for colorectal cancer.
  • Further research into defensin expression patterns in CRC is warranted.

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...

Renewal of Intestinal Stem Cells01:23

Renewal of Intestinal Stem Cells

The intestinal epithelial lining rapidly renews every 4 to 5 days. The renewal is facilitated by intestinal stem cells (ISCs) located at the base of the crypt– a gland located at the bottom of each villus. ISCs divide asymmetrically to form new stem cells and progenitor daughter cells. The daughter cells are called transit-amplifying (TA) cells which move upwards along the crypt and either differentiate into absorptive cells– the enterocytes or secretory cells– including the...

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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.

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,...
