Insights

Cancer cells resist chemotherapy by altering cell cycle genes, leading to drug resistance. This review explores resistance mechanisms and natural compounds for new chemotherapy strategies.

Area of Science:

  • Oncology
  • Cell Biology
  • Pharmacology

Background:

  • Cancer cells exhibit altered cell cycle genes or mutations, resulting in uncontrolled proliferation.
  • Dysregulation of mitosis due to genetic alterations drives tumor progression and drug resistance.
  • Antimitotic agents like vinca alkaloids and taxanes target microtubule proteins (α-β-tubulin heterodimers) crucial for cell division.

Purpose of the Study:

  • To review key targets in cancer cells that confer resistance to antimitotic chemotherapy.
  • To elucidate the mechanisms by which cancer cells develop resistance to established drugs.
  • To highlight novel therapeutic agents from natural sources for overcoming chemotherapy resistance.

Main Methods:

  • Literature review focusing on cell cycle regulation, mitosis, and drug resistance in cancer.
  • Analysis of the role of β-tubulin isotypes, particularly βIII-tubulin, in cancer.
  • Identification and evaluation of natural compounds with potential antimitotic or resistance-modulating activities.

Main Results:

  • Alterations in cell cycle genes and βIII-tubulin expression are implicated in cancer's resistance to antimitotic drugs.
  • Cancer cells develop resistance, rendering initial chemotherapy regimens ineffective over time.
  • Natural sources offer promising compounds that may circumvent existing resistance mechanisms.

Conclusions:

  • Understanding cancer cell resistance mechanisms is crucial for developing effective chemotherapy.
  • Targeting specific tubulin isotypes and exploring natural compounds represent a promising avenue for novel cancer treatments.
  • A new approach to chemotherapy integrating resistance modulation is needed to improve patient outcomes.

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...

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...

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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...

Microtubule Formation01:23

Microtubule Formation

Microtubules are dynamic structures that undergo continuous assembly and disassembly. They originate from specialized multi-protein complexes known as microtubule organizing centers or MTOCs. Within the MTOC, the point of origin of the microtubule is known as the minus end, while the end radiating outward is the plus end. Microtubules serve two primary functions — the organization of spindle complexes to separate sister chromatids during mitotic or meiotic cell division and the formation...

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 mTOR pathway or the...
