Insights

Human Papillomavirus (HPV) infection drives cervical cancer through gene expression changes impacting the tumor microenvironment. Key immune-related genes are altered, affecting immune cell patterns and potentially offering new therapeutic targets.

Area of Science:

  • Oncology
  • Immunology
  • Genomics

Background:

  • Cervical cancer progression is linked to Human Papillomavirus (HPV) infection and tumor microenvironment alterations.
  • Understanding HPV-induced immune evasion mechanisms is vital for effective cervical cancer therapies.

Purpose of the Study:

  • To identify differentially expressed genes (DEGs) in HPV-positive versus HPV-negative cervical cancer.
  • To explore the role of these DEGs in immune evasion and identify potential therapeutic targets.

Main Methods:

  • Transcriptomic analysis of three independent cervical cancer datasets (GSE127265, GSE166466, GSE218460).
  • Construction of protein-protein interaction networks using Cytoscape and STRING.
  • Assessment of immune infiltration using the TIMER database and pathway enrichment analysis.

Main Results:

  • Identified 572 common DEGs between tumor and normal tissues, with distinct profiles in HPV-positive samples.
  • Downregulated hub genes were linked to immune regulation and receptor tyrosine kinase signaling.
  • Observed altered dendritic cell and T cell infiltration, implicating HPV in immune modulation and impaired leukocyte transendothelial migration.

Conclusions:

  • Immune-related hub genes play a critical role in HPV-driven cervical cancer progression.
  • Findings suggest potential therapeutic strategies targeting HPV-induced immune suppression.

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
