Abstract

Insights

MicroRNAs, crucial epigenetic regulators, are often altered in Mycosis fungoides (MF). Understanding their role in MF progression and apoptosis is key for diagnosis and prognosis.

Area of Science:

  • Oncology
  • Dermatology
  • Epigenetics

Background:

  • Mycosis fungoides (MF) is a skin cancer where oncogenic microRNAs (miRNAs), acting as epigenetic inhibitors, are frequently deregulated.
  • These deregulated miRNAs play a role in the transformation and spread of MF.

Purpose of the Study:

  • To investigate the role of microRNA dysregulation in Mycosis fungoides.
  • To explore the signaling pathways involved in microRNA regulation in MF.
  • To assess the potential of microRNAs as diagnostic and prognostic markers for MF.

Main Methods:

  • Analysis of microRNA expression in MF patient skin biopsies.
  • Investigation of signaling pathways, including the STAT pathway, influencing miRNA expression.
  • Elucidation of molecular mechanisms of miRNA regulation in MF.

Main Results:

  • De-expression of specific microRNAs was observed in MF patient skin biopsies.
  • MicroRNAs were found to regulate and be regulated by various signaling pathways, including the STAT pathway.
  • The STAT signaling pathway's role in promoting diverse miRNA expression via cytokine receptors and JAK-STAT activation was elucidated, though some non-STAT pathways remain incompletely understood.

Conclusions:

  • MicroRNAs demonstrate potential as prognostic, progression, and diagnostic markers for Mycosis fungoides.
  • MicroRNAs can effectively control MF cell proliferation and induce apoptosis, highlighting their therapeutic relevance.

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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.

MicroRNAs01:22

MicroRNAs

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...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

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...
