Abstract

Insights

Evodiamine triggers apoptosis in HeLa cells via cell cycle arrest, but induces both apoptosis and necrosis in melanoma cells through different pathways. This study clarifies evodiamine

Area of Science:

  • Pharmacology
  • Cancer Biology
  • Cell Death Pathways

Background:

  • Evodiamine is a natural alkaloid with potential anti-cancer properties.
  • Understanding its mechanism of action is crucial for therapeutic development.
  • Cervical cancer (HeLa) and melanoma (A375-S2) cells represent distinct cancer types with different cellular responses.

Purpose of the Study:

  • To investigate the distinct cell death pathways induced by evodiamine in human cervical cancer (HeLa) and melanoma (A375-S2) cells.
  • To elucidate the molecular mechanisms underlying evodiamine's cytotoxic effects.

Main Methods:

  • Cell viability was assessed using MTT assays.
  • Apoptosis was visualized via Hoechst 33258 staining and DNA fragmentation analysis.
  • Necrosis was quantified using lactate dehydrogenase (LDH) release assays.
  • Cell cycle distribution was analyzed by flow cytometry.
  • Protein activation (caspase-3, -8, p38, ERK) was implied in the results.

Main Results:

  • Evodiamine induced dose- and time-dependent cell death in both HeLa and A375-S2 cells.
  • In HeLa cells, evodiamine triggered apoptosis associated with G2/M cell cycle arrest and caspase-3/8 activation.
  • In A375-S2 cells, evodiamine induced early caspase-3/8-mediated apoptosis and later MAPK (p38/ERK)-related necrosis.

Conclusions:

  • Evodiamine exhibits differential effects on cell death pathways in HeLa and A375-S2 cells.
  • HeLa cells undergo apoptosis linked to G2/M cell cycle arrest.
  • A375-S2 cells experience a dual death pathway involving early apoptosis and later necrosis mediated by MAPK signaling.

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...
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.
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...
Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
Cytotoxic Edema: Pathophysiology01:21

Cytotoxic Edema: Pathophysiology

Cytotoxic edema is a form of cerebral edema characterized by intracellular swelling of neurons, astrocytes, and other glial cells. It develops when the mechanisms responsible for maintaining ionic gradients across the cell membrane become impaired. Under normal physiological conditions, the sodium–potassium ATPase actively transports sodium ions out of the cell and potassium ions into the cell, preserving osmotic balance and enabling electrical signaling. This pump requires a continuous supply...
