Insights

The promyelocytic leukaemia (PML) gene, central to acute promyelocytic leukaemia, forms PML nuclear bodies. These structures regulate cell growth and survival, with ongoing research exploring novel functions.

Area of Science:

  • Molecular Biology
  • Cancer Genetics
  • Cell Biology

Background:

  • The promyelocytic leukaemia (PML) gene was initially discovered due to the t(15;17) translocation characteristic of acute promyelocytic leukaemia.
  • This translocation results in the formation of the PML-retinoic acid receptor alpha (PML-RARα) oncogene.
  • PML is a key component of subnuclear structures known as PML nuclear bodies.

Purpose of the Study:

  • To review the current understanding of PML gene function and PML nuclear bodies.
  • To explore the proposed roles of PML in controlling cell growth and survival.
  • To identify and suggest new research directions for investigating PML.

Main Methods:

  • Literature review of existing studies on the PML gene and PML nuclear bodies.
  • Analysis of current models detailing PML's proposed functions.
  • Identification of gaps in knowledge and potential future research avenues.

Main Results:

  • PML gene is intrinsically linked to acute promyelocytic leukaemia and the PML-RARα oncogene.
  • PML nuclear bodies, built around the PML protein, are implicated in cellular regulation.
  • PML's scaffold properties are hypothesized to mediate control over cell growth and survival pathways.

Conclusions:

  • The PML gene and its associated nuclear bodies play a critical role in cellular processes.
  • Further investigation is warranted to fully elucidate the multifaceted functions of PML in cell growth and survival.
  • Exploring novel avenues of research can uncover new therapeutic targets related to PML in various cancers.

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...
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...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
Negative Regulator Molecules01:23

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
