MicroRNAs01:22

MicroRNAs

3.1K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.2K
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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

2.1K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • MicroRNA (miRNA) expression is frequently altered in various cancers, including colorectal cancer (CRC).
  • Adiponectin plays a regulatory role in tumorigenesis, and its signaling pathway is implicated in CRC development.
  • Understanding the interplay between miRNAs, adiponectin signaling, and CRC is crucial for advancing cancer research.

Purpose of the Study:

  • To identify a consistent panel of dysregulated miRNAs in CRC that target the adiponectin signaling pathway.
  • To explore the potential role of these miRNAs as key regulators in CRC pathogenesis.
  • To integrate bioinformatics analysis with existing literature to provide a comprehensive overview.

Main Methods:

  • Utilized bioinformatics tools to analyze public datasets for miRNAs targeting the adiponectin pathway in CRC.
  • Conducted a comprehensive literature review on CRC, adiponectin signaling, and miRNA dysregulation.
  • Performed gene ontology enrichment analysis to elucidate affected biological processes and pathways.

Main Results:

  • Identified a set of miRNAs consistently altered in CRC that target adiponectin signaling.
  • Several candidate miRNAs, including miR-215-5p, miR-340-5p, miR-181a-5p, miR-150-5p, miR-96-5p, miR-19a-3p, and miR-21-5p, were highlighted as potential key regulators.
  • Gene ontology analysis provided insights into the biological pathways influenced by these miRNAs in CRC.

Conclusions:

  • The study successfully identified specific miRNAs that are significantly dysregulated in CRC and affect adiponectin signaling.
  • These miRNAs represent potential novel biomarkers and therapeutic targets for colorectal cancer.
  • No prior literature reported a direct link between the identified miRNAs, adiponectin signaling, and CRC pathogenesis, highlighting the novelty of these findings.
