Abstract

Insights

Proteasome inhibitors are a new drug class that can stop cancer cell growth and trigger cell death. Clinical trials are underway to explore their use as anti-tumor drugs for various human cancers.

Area of Science:

  • Molecular Biology
  • Oncology
  • Pharmacology

Background:

  • The proteasome is a critical cellular machine involved in protein degradation.
  • Dysregulation of proteasome function is implicated in various cancers.
  • Apoptosis, or programmed cell death, is a key target for cancer therapies.

Purpose of the Study:

  • To review current understanding of proteasome's role in apoptosis.
  • To explore the therapeutic potential of proteasome inhibitors in cancer treatment.
  • To discuss novel strategies for developing proteasome-targeted anti-cancer drugs.

Main Methods:

  • Review of existing scientific literature on proteasome inhibitors and apoptosis.
  • Analysis of preclinical data on proteasome inhibitor efficacy in tumor models.
  • Examination of clinical trial outcomes for proteasome inhibitor-based cancer therapies.

Main Results:

  • Proteasome inhibitors disrupt nuclear factor-kappa B activation and modulate apoptotic pathways.
  • These inhibitors induce apoptosis and inhibit proliferation in numerous cancer cell lines and models.
  • Bortezomib, an FDA-approved proteasome inhibitor, demonstrates significant anti-tumor activity.

Conclusions:

  • Proteasome inhibitors show significant promise as anti-cancer agents based on in vitro and in vivo studies.
  • Clinical trials are actively investigating proteasome inhibitors for diverse human cancers.
  • Ongoing research focuses on developing next-generation proteasome inhibitors with enhanced anti-tumor efficacy.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
The Proteasome01:13

The Proteasome

Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3 (ubiquitin...

Caspases01:24

Caspases

Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside cells.
The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
