Drugs that Stabilize Microtubules01:15

Drugs that Stabilize Microtubules

2.8K
Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

9.0K
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...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

13.4K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Drugs that Destabilize Microtubules

4.1K
Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...

Abnormal Proliferation02:23

Abnormal Proliferation

5.3K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Transducer Mechanism: Enzyme-Linked Receptors01:27

Transducer Mechanism: Enzyme-Linked Receptors

4.5K
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:

Area of Science:

  • Oncology
  • Immunology
  • Molecular Biology

Background:

  • The tumor microenvironment involves complex intercellular communication essential for tumor growth and metastasis.
  • Signal transducer and activator of transcription 3 (STAT3) signaling is critical for tumor cell proliferation, survival, and modulation of the tumor microenvironment.
  • Aberrant STAT3 activation, often induced by IL-6 and IL-10 family cytokines, is a hallmark of many malignancies.

Purpose of the Study:

  • To provide an update on the role of STAT3 in immune suppression within the tumor microenvironment.
  • To describe current therapeutic strategies targeting the Janus kinase (JAK)/STAT3 signaling axis for cancer treatment.

Main Methods:

  • Review of existing literature on STAT3 signaling in cancer and immune suppression.
  • Analysis of therapeutic strategies targeting the JAK/STAT3 pathway.

Main Results:

  • STAT3 signaling influences both tumor cell-intrinsic properties and the functions of surrounding immune and stromal cells.
  • Tumor-extrinsic STAT3 signaling contributes to immune suppression by impairing anti-tumor immune responses.
  • The JAK/STAT3 pathway is implicated in mediating tumorigenic effects across various cell types.

Conclusions:

  • STAT3 plays a dual role in cancer, promoting tumor growth and mediating immune suppression.
  • The molecular components of the JAK/STAT3 pathway represent viable therapeutic targets for cancer treatment.
  • Targeting the JAK/STAT3 axis is a promising strategy for overcoming immune evasion and treating malignancies.
