Insights

Plant sphingoid bases from wheat cerebroside induce apoptosis in human colorectal cancer cells. These compounds reduce cell viability, offering potential therapeutic strategies for colon cancer.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Cancer Research

Background:

  • Colorectal cancer (CRC) remains a significant global health challenge.
  • Cerebrosides and their derivatives are explored for potential anti-cancer properties.
  • Understanding the mechanisms of plant-derived compounds on cancer cells is crucial.

Purpose of the Study:

  • To investigate the apoptotic effects of plant sphingoid bases derived from wheat-flour cerebroside on human colorectal cancer DLD-1 cells.
  • To determine the dose-dependency and mechanism of cell death induced by these compounds.

Main Methods:

  • Treatment of human colorectal cancer DLD-1 cells with varying concentrations of plant sphingoid bases.
  • Assessment of cell viability using standard assays.
  • Microscopic examination for morphological changes indicative of apoptosis.

Main Results:

  • Plant sphingoid bases significantly reduced DLD-1 cell viability in a dose-dependent manner.
  • The observed reduction in cell viability was comparable to that induced by pure sphingosine.
  • Morphological analysis revealed characteristic apoptotic features, including condensed chromatin fragments.

Conclusions:

  • Plant sphingoid bases derived from wheat-flour cerebroside exhibit potent apoptotic effects on human colorectal cancer cells.
  • These findings suggest that plant sphingoid bases can induce cell death through apoptosis.
  • The study highlights the potential of these natural compounds as therapeutic agents against colorectal cancer.

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...
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...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or  immature dendritic cells. Non-professional phagocytes such as  epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
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...
