Abstract

Insights

Vinblastine (VBL) chemotherapy in cervical carcinoma cells induced G2/M arrest and altered gene expression. This study reveals VBL

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Effective chemotherapy is needed for early-stage, high-risk cervical carcinoma.
  • Vinblastine (VBL) is a microtubule inhibitor with unproven mechanisms in cervical cancer.

Purpose of the Study:

  • To investigate the molecular mechanisms of Vinblastine (VBL) in cervical carcinoma cells.
  • To identify potential therapeutic targets for VBL-based chemotherapy.

Main Methods:

  • KB-3 cervical carcinoma cells were treated with VBL at a concentration inducing 30% cell death.
  • Analyses included DNA content, gene expression, and transcriptional gene regulation.
  • Transcriptomic and functional pathway analyses were performed.

Main Results:

  • VBL treatment induced G2/M cell cycle arrest in KB-3 cells.
  • Gene expression was altered, regulated by transcription factors AP1, NFKB1, RELA, and TP53.
  • Key pathways affected include protein ubiquitination, RhoGDI signaling, and integrin signaling.

Conclusions:

  • VBL alters gene expression and cell cycle progression in cervical carcinoma cells.
  • Understanding these transcriptional changes offers a new strategy for VBL chemotherapy.
  • Identified pathways and regulated genes may serve as therapeutic targets.

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Drugs that Destabilize Microtubules

Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...

Destabilization of Microtubules01:45

Destabilization of Microtubules

The destabilization of microtubules can occur during different stages of the microtubule lifecycle, such as nucleation or elongation. It can take place at either end of the microtubule or in the microtubule lattices as a whole. The lifespan of individual microtubules within a cell varies according to the cell type and stage of the cell cycle. During interphase, the lifespan of the microtubule is about 30 minutes, while during cell division, it is about 15 minutes. In axonal microtubules of...

Microtubules in Cell Motility

Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
