Insights

Nifuratel, an existing drug, effectively inhibits signal transducer and activator of transcription 3 (STAT3) in gastric cancer cells. This finding suggests nifuratel as a potential new chemotherapy drug for gastric cancer by blocking STAT3 activation.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Signal transducer and activator of transcription 3 (STAT3) activation is prevalent in various cancers, including gastric cancer.
  • STAT3 is a promising therapeutic target for cancer chemotherapy.
  • There is a lack of clinically approved small-molecule inhibitors for STAT3.

Purpose of the Study:

  • To investigate nifuratel as a potential STAT3 inhibitor.
  • To evaluate the efficacy of nifuratel in gastric cancer cells.
  • To elucidate the mechanism of action of nifuratel on STAT3 signaling.

Main Methods:

  • Assessing nifuratel's effect on gastric cancer cell proliferation and apoptosis.
  • Analyzing nifuratel's impact on constitutive and interleukin-6-induced STAT3 activation.
  • Investigating the molecular mechanisms underlying nifuratel's action.

Main Results:

  • Nifuratel demonstrated significant suppression of gastric cancer cell proliferation.
  • Nifuratel effectively induced apoptosis in gastric cancer cells.
  • Nifuratel was found to inhibit both constitutive and IL-6-induced STAT3 activation.

Conclusions:

  • Nifuratel is a potent inhibitor of STAT3.
  • Nifuratel exhibits anti-cancer effects in gastric cancer cells.
  • Nifuratel represents a potential novel, clinically accessible STAT3 inhibitor for gastric cancer treatment.

Drugs that Stabilize Microtubules

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...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy.  SP binds and activates...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists01:28

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists

Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Drugs that Destabilize Microtubules

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...
