lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

9.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

8.3K
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

5.2K
Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Metastasis02:30

Metastasis

6.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

The Ras Gene02:38

The Ras Gene

7.0K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

Area of Science:

  • Molecular Biology
  • Cancer Biology
  • Genetics

Background:

  • GATA transcription factors are key regulators of tissue development, cell differentiation, and homeostasis.
  • Dysregulated GATA factors are implicated in tumorigenesis, cancer progression, and metastasis, influencing oncogenic processes.
  • Non-coding RNAs critically regulate gene expression and are emerging as key players in cancer.

Purpose of the Study:

  • To review the role of GATA factors in epithelial-mesenchymal transition (EMT) and metastasis.
  • To explore the largely uninvestigated interplay between non-coding RNAs and GATA transcription factors in cancer.
  • To propose a novel regulatory axis for potential therapeutic targeting and biomarker discovery.

Main Methods:

  • Literature review focusing on GATA factors, non-coding RNAs, and cancer progression.
  • Analysis of existing research on GATA factor function in development and disease.
  • Synthesis of findings on non-coding RNA-mediated regulation of gene expression.

Main Results:

  • GATA factors promote proliferation in progenitor cells and cell cycle arrest in differentiating cells.
  • Mutations in GATA factors correlate with poor prognosis and influence multiple oncogenic pathways.
  • Non-coding RNAs can act as tumor suppressors or oncogenes by modulating gene expression.

Conclusions:

  • GATA factors play complex, context-dependent roles in cancer, influencing EMT and metastasis.
  • The interaction between non-coding RNAs and GATA factors in cancer progression is a critical, underexplored area.
  • Understanding this interplay may reveal novel biomarkers and therapeutic strategies for cancer treatment.
