Insights

The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway plays a dual role in cancer, influencing tumor development and response to therapies like STING agonists and oncolytic viruses.

Area of Science:

  • Immunology
  • Oncology
  • Molecular Biology

Background:

  • The cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway is crucial for innate immunity against microbes.
  • This pathway can be activated by self-DNA in tumors, impacting cancer development.
  • Dysregulation of the cGAS-STING pathway is implicated in various cancers.

Purpose of the Study:

  • To review and discuss the dual roles of the cGAS-STING pathway in cancer.
  • To explore therapeutic strategies targeting the cGAS-STING pathway in cancer treatment.
  • To examine the potential of oncolytic virus therapy in cancers with deficient cGAS-STING signaling.

Main Methods:

  • Literature review of studies on the cGAS-STING pathway in cancer.
  • Analysis of research on STING agonists and their combination therapies.
  • Evaluation of oncolytic virus therapy in the context of cGAS-STING pathway deficiency.

Main Results:

  • The cGAS-STING pathway exhibits dichotomous effects, promoting or inhibiting tumor growth.
  • STING agonists are being developed as cancer therapeutics, alone or in combination.
  • Oncolytic virus therapy shows promise for cancers lacking functional cGAS-STING signaling.

Conclusions:

  • The cGAS-STING pathway is a critical regulator in cancer immunity and development.
  • Targeting the cGAS-STING pathway offers promising therapeutic avenues for cancer treatment.
  • Understanding cGAS-STING pathway status is essential for selecting appropriate cancer therapies.

Role of ER in the Secretory Pathway

Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...

C4 Pathway and CAM01:27

C4 Pathway and CAM

Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The C4 pathway is used by plants such as...

Role of Septins01:02

Role of Septins

Septins are the recently discovered fourth major protein component of the cytoskeleton, along with microfilaments, microtubules, and intermediate filaments. These proteins can associate with other cytoskeletal filaments and carry out varied roles or can be free-floating in the cytoplasm.
Cellular Functions of Septins
Recent studies have revealed the multifaceted roles of septins in various cellular processes such as cytokinesis, ciliogenesis, and neurogenesis. Septins act as scaffolds and...

Other Glycolytic Pathways01:24

Other Glycolytic Pathways

The pentose phosphate pathway (PPP) operates in parallel with glycolysis, facilitating the metabolism of both pentoses and glucose. This pathway consists of two distinct phases: the oxidative and non-oxidative phases. While it does not directly generate ATP, the intermediates formed during the process can integrate into glycolysis, contributing to cellular energy metabolism when required.Oxidative Phase: NADPH ProductionThe oxidative phase of the pentose phosphate pathway is primarily...

Auditory Pathway01:15

Auditory Pathway

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking...

ER Retrieval Pathway01:45

ER Retrieval Pathway

In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...
