Expert Opinion on Therapeutic Targets
|August 13, 2008
Summary
Short-term starvation (STS) can enhance differential stress resistance (DSR) in normal cells over cancer cells. Further research into STS-induced DSR mechanisms in mammals is needed before clinical trials.
Area of Science:
- Oncology
- Cell Biology
- Metabolism
Background:
- Raffaghello et al. investigated short-term starvation (STS) to induce differential stress resistance (DSR).
- DSR enhances normal cell protection against chemotherapy-induced oxidative stress.
- The study utilized various model organisms, including yeast, mammalian cell cultures, and mice.
Discussion:
- The findings suggest STS as a potential strategy to improve cancer therapy outcomes.
- Understanding the molecular pathways of STS-induced DSR is crucial.
- The study highlights the link between calorie restriction, proliferation, and disease prevention.
Key Insights:
- STS successfully induced DSR across diverse model systems.
- Normal cells exhibit increased resistance to oxidative stress post-STS.
- Cancer cells may be more vulnerable to chemotherapy after STS.
Outlook:
- Further elucidation of molecular mechanisms underlying STS-induced DSR in mammals is recommended.
- Clinical trials testing STS as a cancer treatment adjuvant should be approached cautiously.
- Investigating the role of proliferation braking in STS-mediated disease prevention is warranted.

01:27Chemotherapy-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,...
01:28Chemotherapy-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 these...
02:49Cancer Therapies
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

01:29Chemotherapy-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.

01:21Chemotherapy-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.
