Treatment Resistant Cancers02:56

Treatment Resistant Cancers

3.6K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Bone Marrow Sampling and Transplants

743
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.6K
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...

Cancer Therapies

9.7K
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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.5K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

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

Chemotherapy-Induced Nausea and Vomiting: Dopamine Receptor Antagonists

733
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...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Pharmacology

Background:

  • The ubiquitin-proteasome system regulates crucial cellular processes like protein turnover, cell cycle, and immune responses.
  • Dysregulation of this system presents therapeutic opportunities for various diseases.
  • Proteasome inhibitors were initially developed as research tools to study proteasome function.

Purpose of the Study:

  • To explore the therapeutic potential of proteasome inhibitors.
  • To review the development and clinical application of proteasome inhibitors.

Main Methods:

  • Synthesis of peptide-based proteasome inhibitors with specific warheads (e.g., boronic acids, epoxyketones).
  • Investigation of natural products with proteasome inhibitory activity.
  • Clinical evaluation of proteasome inhibitors in cancer cell lines and patient populations.

Main Results:

  • Bortezomib, a boronic acid-based inhibitor, demonstrated efficacy in non-small cell lung cancer, prostate cancer, and various lymphomas.
  • Natural product inhibitors like lactacystin and salinosporamide A also show promise.
  • Bortezomib is approved for treating multiple myeloma (MM) and has improved patient outcomes.

Conclusions:

  • Proteasome inhibitors represent a significant advancement in targeted cancer therapy.
  • Bortezomib has revolutionized the treatment landscape for multiple myeloma.
  • Further research into proteasome inhibitors holds promise for broader therapeutic applications.
