Abstract

Insights

The Sonic hedgehog (Shh) signaling pathway is activated in Myelodysplastic Syndrome (MDS). Inhibiting this pathway with jervine shows potential as a therapeutic strategy for MDS patients.

Area of Science:

  • Hematology
  • Molecular Biology
  • Oncology

Background:

  • Myelodysplastic Syndrome (MDS) is a group of clonal hematopoietic stem cell disorders.
  • The Sonic hedgehog (Shh) signaling pathway plays a role in various cellular processes, including development and disease.

Purpose of the Study:

  • To investigate the role of the Shh signaling pathway in MDS occurrence and progression.
  • To evaluate jervine as a potential therapeutic agent for MDS by targeting the Shh pathway.

Main Methods:

  • Analysis of Shh pathway components (Shh, Smo, Ptch-1, Gli-1) in bone marrow CD34+ cells from MDS patients using RT-qPCR.
  • Correlation analysis of Shh pathway gene expression with clinical features and prognosis.
  • Assessment of jervine's effects on MUTZ-1 cell proliferation, apoptosis, cell cycle, and Shh pathway gene/protein expression.

Main Results:

  • Significantly increased expression of Shh, Gli-1, and Smo in MDS patients.
  • Correlation of Smo and Gli-1 expression with chromosome karyotype and IPSS, indicating a link to poor prognosis.
  • Jervine inhibited Shh pathway gene/protein expression, suppressed proliferation, promoted apoptosis, and arrested the cell cycle in MUTZ-1 cells.

Conclusions:

  • Abnormal activation of the Shh signaling pathway is implicated in MDS pathogenesis.
  • Jervine demonstrates potential as a therapeutic strategy for MDS by modulating the Shh pathway.

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...

Differentiation of Common Myeloid Progenitor Cells

Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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...
