Abstract:
Class III β-tubulin (βIII-tubulin) is frequently overexpressed in human tumors and is associated with resistance to microtubule-targeting agents, tumor aggressiveness, and poor patient outcome. Understanding the mechanisms regulating βIII-tubulin expression and the varied functions βIII-tubulin may have in different cancers is vital to assess the prognostic value of this protein and to develop strategies to enhance therapeutic benefits in βIII-tubulin overexpressing tumors. Here we gather all the available evidence regarding the clinical implications of βIII-tubulin overexpression in cancer, describe factors that regulate βIII-tubulin expression, and discuss current understanding of the mechanisms underlying βIII-tubulin-mediated resistance to microtubule-targeting agents and tumor aggressiveness. Finally, we provide an overview of emerging therapeutic strategies to target tumors that overexpress βIII-tubulin.

- Analysis of studies investigating βIII-tubulin expression regulation.
- Synthesis of data on mechanisms of resistance and aggressiveness.
- Overview of emerging therapeutic strategies targeting βIII-tubulin.
Main Results:
- βIII-tubulin overexpression is a significant prognostic marker across multiple cancer types.
- Factors influencing βIII-tubulin expression include genetic and epigenetic mechanisms.
- βIII-tubulin contributes to resistance against microtubule-targeting agents.
- Elevated βIII-tubulin levels are associated with increased tumor cell motility and invasiveness.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
