Similarly, no major difference between NSCLC histological subtypes in HMGA1 gene or protein expression was observed by Zhang et al. (2014) and Zhang et al. (2019) but HMGA1 protein was detected more often in the squamous cell carcinoma subtype compared to adenocarcinoma by Lin and Peng (2016). The gene discussed is HMGA1; the disease is adenocarcinoma.
