Insights

Nucleotide-binding domain, leucine-rich repeat containing receptors (NLRs) are key in immunity and inflammation. This review explores their controversial roles in cancer and potential as therapeutic targets.

Area of Science:

  • Immunology
  • Molecular Biology
  • Oncology

Background:

  • Nucleotide-binding domain, leucine-rich repeat containing receptors (NLRs) function as pattern recognition receptors, crucial for innate immunity.
  • NLRs detect pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs), initiating inflammatory responses.
  • Dysregulation of NLRs is implicated in various diseases, including cancer, metabolic disorders, and autoimmune conditions.

Purpose of the Study:

  • To review the current understanding of NLRs' roles in cancer initiation, development, and progression.
  • To explore the controversial and emerging functions of NLRs within the tumor microenvironment.
  • To discuss the potential of NLRs as therapeutic targets for cancer treatment.

Main Methods:

  • Literature review of peer-reviewed studies on NLRs and cancer.
  • Analysis of experimental and clinical data regarding NLR expression and function in various cancers.
  • Synthesis of findings to present a comprehensive overview of NLRs in oncology.

Main Results:

  • NLRs exhibit diverse and context-dependent roles in cancer, acting as both tumor suppressors and promoters.
  • Specific NLRs have been identified to influence immune surveillance, inflammation, and cellular processes critical to tumorigenesis.
  • Evidence suggests that targeting NLR pathways could modulate anti-tumor immunity and cancer cell behavior.

Conclusions:

  • The role of NLRs in cancer is complex and multifaceted, requiring further investigation.
  • NLRs represent promising targets for novel cancer therapeutics, potentially enhancing existing treatment strategies.
  • Future research should focus on elucidating cell- and organ-specific functions of NLRs to optimize therapeutic applications.

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

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.

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 Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
