Insights

Reovirus therapy for multiple myeloma (MM) induces apoptosis and upregulates autophagy. Understanding these cell death mechanisms is crucial for advancing reovirus as a standard MM treatment.

Area of Science:

  • Oncology
  • Virology
  • Cell Biology

Background:

  • Multiple myeloma (MM) is an incurable hematological cancer.
  • Reovirus shows oncolytic potential and is in clinical trials for solid tumors and MM.
  • The precise mechanisms of reovirus-induced cell death in MM are not fully understood.

Purpose of the Study:

  • To elucidate the mechanisms of reovirus-mediated cell death in multiple myeloma.
  • To investigate whether reovirus induces apoptosis and/or autophagy in MM cells.

Main Methods:

  • In vitro studies using multiple myeloma cell lines.
  • Analysis of cell death pathways, including apoptosis and autophagy, following reovirus infection.

Main Results:

  • Reovirus infection of MM cells induces apoptosis.
  • Reovirus infection upregulates autophagy in MM cells.
  • This study is the first to demonstrate dual induction of apoptosis and autophagy by reovirus in MM.

Conclusions:

  • Reovirus utilizes both apoptosis and autophagy to mediate oncolysis in multiple myeloma.
  • Understanding these pathways is essential for optimizing reovirus-based therapies for MM.

Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...
Autophagy01:27

Autophagy

Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...
