Neural Circuits

1.4K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Ligand-Gated Ion Channel Receptor: Gating Mechanism

2.4K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

Transducer Mechanism: Enzyme-Linked Receptors

2.6K
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

7.8K
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...

Area of Science:

  • Oncology and Molecular Biology: Focuses on the molecular mechanisms of cancer, particularly RAS signaling pathways.

Background:

  • RAS oncogene mutations are implicated in approximately 33% of human cancers, presenting significant therapeutic challenges.
  • RAS signaling pathways are critical for cancer cell growth, survival, plasticity, and metastasis.
  • Dysregulation of post-transcriptional mechanisms controlling RAS circuitry contributes to cancer progression.

Approach:

  • This review examines the intricate RAS circuitry and its downstream effectors in various cancer types.
  • It explores how understanding RAS signaling can inform the development of novel anti-cancer therapeutics.
  • Strategies for overcoming therapeutic resistance in RAS-mutant cancers are discussed, emphasizing combination therapies.

Key Points:

  • RAS circuitry activation of downstream effectors is context-dependent on cancer type and grade.
  • Altered post-transcriptional regulation of RAS pathways promotes metabolic and immunological states favorable to cancer.
