Disease relevance of KIF14


High impact information on KIF14


Biological context of KIF14

  • KIF14 is a candidate oncogene in the 1q minimal region of genomic gain in multiple cancers [1].
  • Cells at later stages of mitosis were characterized by the concentration of KIF14 at the midbody [4].
  • Furthermore, the link we observed between siRNA efficacy and phenotypic outcome indicates that distinct stages during cell cycle progression are disrupted by the differential modulation of KIF14 expression [4].
  • Time-lapse microscopy revealed that strong RNA interference (RNAi)-mediated silencing of KIF14 induced cytokinesis failure, causing several rounds of endoreduplication and resulting in multinucleated cells [4].
  • Additionally, less efficacious KIF14-specific short interfering RNAs (siRNAs) induced multiple phenotypes, all of which resulted in acute apoptosis [4].

Anatomical context of KIF14

  • KIF14 expression correlated positively with Ki-67 mRNA level (Spearman r = 0.692, p = 0.000001), fraction of positive nodes (r = 0.227, p = 0.024) and percent invasive cells (r = 0.360, p = 0.0002), and negatively with percent fatty stroma (r = -0.258, p = 0.010) and percent normal epithelium (r = -0.291, p = 0.003) [5].

Other interactions of KIF14

  • Of these, only KIF14, a putative chromokinesin, was overexpressed in various cancers by real-time RT-PCR [1].
  • Measured by real-time RT-PCR, KIF14 was overexpressed 10-fold on average in tumors relative to normals (t test p = 0.000054); expression increased with grade (ANOVA p = 0.000006) [5].
