In contrast to Semaphorin-6A and ZEB1, the overexpression of the Snail family zinc finger transcription factor SLUG in non-small cell lung cancer cells suppressed expression of TUBB3/βIII-tubulin, as well as the β-tubulin isotype, TUBB4A/βIVa-tubulin (Tamura et al., 2013). Here, TUBB3 is linked to non-small cell lung carcinoma.
