Insights

MicroRNAs (miRNAs) like miR-214-3p are crucial in psoriasis development. Targeting the miR-214-3p/FOXM1 pathway in skin cells offers a potential new treatment for psoriasis.

Area of Science:

  • Dermatology
  • Molecular Biology
  • Genetics

Background:

  • Psoriasis is a chronic skin disease with unknown molecular drivers.
  • MicroRNAs (miRNAs) regulate gene expression and are implicated in psoriasis pathogenesis.

Purpose of the Study:

  • To investigate the role of miR-214-3p in psoriasis.
  • To explore the miR-214-3p/FOXM1 axis as a potential therapeutic target for psoriasis.

Main Methods:

  • Analysis of miRNA expression in psoriatic patients and mouse models.
  • In vitro studies using HaCaT cells to assess keratinocyte proliferation and cell cycle.
  • In vivo experiments using imiquimod (IMQ)-induced mice to evaluate therapeutic effects.

Main Results:

  • miR-214-3p was downregulated in psoriatic skin and IMQ-induced mouse models.
  • miR-214-3p inhibition promoted keratinocyte hyperproliferation and altered cell cycle gene expression.
  • miR-214-3p administration reduced psoriasis-like symptoms in mice.

Conclusions:

  • The miR-214-3p/FOXM1 axis plays a significant role in keratinocyte regulation.
  • Targeting this axis presents a novel therapeutic strategy for psoriasis treatment.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

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...

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.
The mTOR pathway or the...

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.
