Abstract

Insights

Autophagy, a cellular process, plays a complex role in multiple myeloma (MM) development and progression. Targeting autophagy offers potential for novel MM diagnostics and treatments.

Area of Science:

  • Cellular Biology
  • Oncology
  • Immunology

Background:

  • Autophagy is a fundamental cellular process involved in degrading damaged proteins and organelles.
  • Dysregulation of autophagy is implicated in various diseases, including cancer.
  • Previous research highlights the significance of autophagy in cancer pathogenesis.

Purpose of the Study:

  • To review the role of autophagy in the development of multiple myeloma (MM).
  • To explore autophagy mechanisms in MM within the context of UPR, BMME, drug resistance, hypoxia, and DNA repair.
  • To identify potential therapeutic targets within autophagy-related genes and pathways in MM.

Main Methods:

  • Systematic literature search of PubMed and Google Scholar.
  • Analysis of meta-analyses, case-control studies, and observational studies on autophagy in multiple myeloma.
  • Review of current research on autophagy mechanisms and their relevance to MM.

Main Results:

  • Autophagy exhibits a dual role in cancer, potentially promoting or inhibiting carcinogenesis.
  • Autophagy is critical for B cell fate, influencing survival or cell death.
  • Autophagy modulation is discussed concerning UPR, BMME, drug resistance, hypoxia, and DNA repair in MM.

Conclusions:

  • Autophagy gene expression analysis may aid in MM diagnosis and personalized treatment.
  • Modulating autophagy presents a promising therapeutic strategy to limit MM progression and enhance treatment efficacy.
  • Targeting autophagy pathways could lead to novel molecular targeted therapies for MM.

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,...

Delivery Pathways to the Lysosome01:36

Delivery Pathways to the Lysosome

Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

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...

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...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
