Summary

This summary is machine-generated.

CRP and HNF1A promote laryngeal cancer (LC) progression. Knockdown of these genes inhibits tumor growth, migration, and invasion while enhancing apoptosis, indicating their role in the Wnt signaling pathway and epithelial-mesenchymal transition.

Area Of Science

  • Oncology
  • Molecular Biology
  • Genetics

Background

  • Laryngeal cancer (LC) progression involves complex regulatory mechanisms.
  • Identifying key genes and transcription factors is crucial for understanding LC pathogenesis.

Purpose Of The Study

  • To investigate the regulatory roles of C-reactive protein (CRP) and Hepatocyte Nuclear Factor 1-Alpha (HNF1A) in laryngeal cancer.
  • To elucidate the underlying molecular mechanisms, including the Wnt signaling pathway and epithelial-mesenchymal transition (EMT).

Main Methods

  • Bioinformatics analysis to identify core LC genes and transcription factors.
  • Quantitative Reverse Transcription Polymerase Chain Reaction (QRT-PCR) for gene expression analysis.
  • Cellular assays (CCK-8, flow cytometry, wound-healing, Transwell) for proliferation, apoptosis, migration, and invasion.
  • Dual luciferase assays, ChIP, and EMSA to confirm gene interactions.
  • Western blot and immunohistochemistry for protein expression analysis.
  • In vivo tumorigenesis experiments in nude mice.

Main Results

  • CRP and HNF1A were identified as key genes correlated in LC and were upregulated in human LC tissues.
  • Knockdown of CRP and HNF1A significantly inhibited proliferation, migration, and invasion, while enhancing apoptosis in LC cells.
  • HNF1A knockdown led to downregulation of CRP, β-catenin, Wnt3a, and Vimentin, and upregulation of E-cadherin, suggesting involvement of the Wnt pathway and EMT.
  • In vivo experiments confirmed that CRP knockdown inhibited tumor growth and modulated related protein expressions.

Conclusions

  • CRP and HNF1A act as oncogenes promoting laryngeal cancer progression.
  • These genes exert their effects by activating the Wnt signaling pathway and promoting epithelial-mesenchymal transition.
  • Targeting CRP and HNF1A may represent a potential therapeutic strategy for laryngeal cancer.

Canonical Wnt Signaling Pathway 02:54

8.9K

The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

Non-Canonical Wnt Signaling Pathways 01:41

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...

Abnormal Proliferation 02:23

4.6K

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...

lncRNA - Long Non-coding RNAs 02:39

8.9K

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...

Hedgehog Signaling Pathway 02:33

7.5K

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...

NF-κB-dependent Signaling Pathway 02:26

7.9K

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.
