RP1 and cancer: Notably, RP11-357H14.17 was found to cis-regulate HOXB7, RP1-170O19.14 was observed to cis-regulate both HOXA13 and HOXA10, and AC012531.25 was identified as a cis-regulator of HOXC10 Fig. 3B. These interactions involving homeotic and homeogenetic regulation concerning cancer-related genes warrant further attention.
