Abstract

Insights

This study repurposed antipsychotic drugs, including cabergoline and dopamine, to inhibit gastric cancer (GC) cell growth. These findings suggest potential new therapies for GC by repurposing existing medications.

Area of Science:

  • Oncology
  • Pharmacology
  • Drug Repurposing

Background:

  • Gastric cancer (GC) is a leading cause of cancer mortality worldwide.
  • Understanding shared molecular mechanisms is crucial for developing novel targeted GC therapies.
  • This study utilized a drug repositioning strategy to identify potential GC drug candidates.

Purpose of the Study:

  • To investigate the efficacy of specific drugs as potential gastric cancer treatments.
  • To explore the drug repositioning approach for identifying novel therapeutic agents for GC.

Main Methods:

  • Human GC cell lines (AGS, MKN-45, KATO-III) were treated with dopamine, cabergoline, thioridazine, and entacapone.
  • Cytotoxic activity was assessed using the MTT assay.
  • Apoptosis, B-cell lymphoma 2 (Bcl-2), Bcl-2-associated X protein (Bax), and Proliferating Cell Nuclear Antigen (PCNA) expression were evaluated via Annexin V/PI staining and qRT-PCR.

Main Results:

  • Dopamine, cabergoline, thioridazine, and entacapone demonstrated dose-dependent cytotoxic effects and induced apoptosis in AGS and KATO-III cells.
  • These drugs significantly decreased Bcl-2 and PCNA expression while increasing Bax expression in sensitive cell lines.
  • MKN-45 cells did not exhibit similar responses to the tested drugs.

Conclusions:

  • The antipsychotic drugs cabergoline, dopamine, thioridazine, and entacapone show potential in inhibiting gastric cancer cell growth.
  • These findings support the repurposing of these drugs as novel therapeutic agents for gastric cancer treatment.

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

Dopamine receptor antagonists, also known as antipsychotic agents, are critical in managing chemotherapy-induced vomiting. These antiemetic agents block dopamine receptors in the chemoreceptor trigger zone (CTZ), inhibiting signal transmission to the vomiting center. Antipsychotic agents encompass phenothiazines (PTZ), butyrophenones, benzamides, and thienobenzodiazepines (Zyprexa), which are utilized for their antiemetic and sedative properties.
Phenothiazines, such as prochlorperazine...

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,...

Antipsychotic Drugs: Therapeutic Uses and Side Effects

Antipsychotic drugs primarily block dopamine and serotonin receptors and cholinergic, adrenergic, and histaminergic receptors, thereby reducing hallucinations and delusions in conditions like schizophrenia. However, they can trigger unwanted extrapyramidal effects such as dystonias, Parkinson-like symptoms, and tardive dyskinesia.
Despite these side effects, antipsychotics are used therapeutically for various purposes, including managing schizophrenia, preventing nausea and vomiting, curbing...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Targeted Cancer Therapies02:57

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...
