Insights

Lung cancer

Area of Science:

  • Oncology
  • Immunology
  • Molecular Biology

Background:

  • Lung cancer remains a leading cause of cancer death globally, with poor survival rates for advanced stages.
  • Understanding signaling pathway crosstalk is vital for developing targeted lung cancer therapies, particularly for metastasis.
  • Dysregulated Toll-like receptors (TLRs) in lung cancer promote immune escape, angiogenesis, and proliferation.
  • WNT signaling pathway over-activation in lung cancer is linked to metastasis through Epithelial-to-mesenchymal-transition (EMT).

Purpose of the Study:

  • To provide an overview of the interaction between Toll-like receptors (TLRs) and the WNT signaling pathway in lung cancer.
  • To explore the potential implications of TLR-WNT pathway crosstalk in the oncogenic process of lung cancer.
  • To highlight the significance of this interaction in the context of lung cancer progression and metastasis.

Main Methods:

  • Literature review and synthesis of existing research on TLRs and WNT signaling in lung cancer.
  • Analysis of recent findings on the activation of TLRs by WNT ligands in the tumor microenvironment.
  • Discussion of the potential biological and clinical implications of TLR-WNT pathway interplay.

Main Results:

  • A novel interaction where the TLR pathway can be activated by WNT ligands in the tumor microenvironment has been identified.
  • This TLR-WNT pathway crosstalk has not been previously discussed in the context of lung cancer.
  • The interplay between TLRs and WNT signaling presents a new avenue for understanding lung cancer malignancy.

Conclusions:

  • The interaction between Toll-like receptors (TLRs) and the WNT signaling pathway represents a significant, yet understudied, aspect of lung cancer.
  • Further investigation into TLR-WNT crosstalk is crucial for elucidating its role in lung cancer development, immune evasion, and metastasis.
  • Targeting this interaction could offer novel therapeutic strategies for improving outcomes in advanced lung cancer patients.

lncRNA - Long Non-coding RNAs

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...

Canonical Wnt Signaling Pathway02:54

Canonical Wnt Signaling Pathway

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 Pathways01:41

Non-Canonical Wnt Signaling Pathways

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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

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...
