Abstract

Insights

Arctigenin induces apoptosis in ovarian cancer by targeting BCL2-like protein 12 (BCL2L12), a key factor in cancer cell survival. This study highlights arctigenin

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Ovarian cancer is a leading cause of gynecological cancer deaths due to late diagnosis and treatment resistance.
  • BCL2-like protein 12 (BCL2L12) plays an anti-apoptotic role, contributing to treatment challenges in ovarian cancer.
  • Understanding BCL2L12's function is crucial for developing novel therapeutic strategies against ovarian cancer.

Purpose of the Study:

  • To investigate the anti-apoptotic role of BCL2L12 in ovarian cancer.
  • To determine if arctigenin induces apoptosis by targeting BCL2L12 in ovarian cancer cells.
  • To evaluate the therapeutic potential of arctigenin as a BCL2L12 inhibitor.

Main Methods:

  • BCL2L12 knockdown and overexpression in SK-OV-3 and OVCAR-3 ovarian cancer cell lines.
  • Assays for cell viability, proliferation, apoptosis, mitochondrial membrane potential, and reactive oxygen species (ROS).
  • Western blotting for apoptosis- and autophagy-related proteins and analysis of public databases for BCL2L12 expression and prognosis.

Main Results:

  • BCL2L12 is upregulated in ovarian cancer, correlating with advanced stage and poor prognosis.
  • BCL2L12 silencing reduced cell growth, increased apoptosis, and inhibited autophagy.
  • Arctigenin inhibited proliferation, downregulated BCL2L12, and induced apoptosis; BCL2L12 overexpression counteracted these effects.

Conclusions:

  • BCL2L12 functions as an anti-apoptotic factor in ovarian cancer by preserving mitochondrial integrity.
  • Arctigenin effectively induces apoptosis by suppressing BCL2L12 and activating caspase-3/7.
  • Arctigenin demonstrates potential as a low-toxicity therapeutic agent for ovarian cancer by targeting BCL2L12.

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...
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 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.
Cellular Injury V: Apoptosis and Autophagy01:22

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
