Insights

Targeting Translationally Controlled Tumor Protein (TCTP) in cancer cells can induce cell death or tumor reorganization. Sertraline shows promise as a potential cancer treatment, with a clinical study now underway.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Translationally Controlled Tumor Protein (TCTP) plays a critical role in cancer progression.
  • Previous experiments indicated that reducing TCTP levels affects cancer cell viability and tumor structure.

Purpose of the Study:

  • To investigate the functional role of TCTP in cancer.
  • To identify and evaluate pharmacological compounds, specifically sertraline, for their potential in cancer therapy.

Main Methods:

  • Gene knockdown experiments to assess the impact of reduced TCTP on cancer cells.
  • In vitro and in vivo studies to evaluate the anti-cancer effects of sertraline.
  • Analysis of tumor architecture and cell death following TCTP manipulation.

Main Results:

  • Decreasing TCTP levels resulted in either cancer cell death or the formation of normal-like tissue structures.
  • Sertraline demonstrated potential as a therapeutic agent against cancer.
  • A collaborative clinical study involving Columbia University and Johns Hopkins University has been initiated.

Conclusions:

  • TCTP is a crucial target for cancer intervention.
  • Sertraline represents a promising candidate for novel cancer treatments.
  • Further clinical investigation is warranted to confirm the efficacy of sertraline in cancer patients.

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...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

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,...

Psychosis: Goals of Pharmacotherapy

Antipsychotic drugs are a crucial treatment method for acute and chronic psychoses, bipolar illness, and behavioral disorders. The selection of these drugs depends on several factors, including the state of the disease, clinical judgment, possible drug interactions, and the patient's sensitivity to adverse effects. In immediate scenarios, such as delirium and dementia, short-term treatment with low doses of high-potency typical or atypical agents can effectively manage symptom exacerbation.

Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists01:29

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...

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...
