Excessive proliferation, metastasis and immune escape are considered to be hallmarks of cancer contributing to tumor progression . Split hand and foot malformation 1 (SHFM1) is highly expressed in various cancers and has been reported to increase malignant behaviors. However, the biological functions of SHFM1 in esophageal squamous cell carcinomas (ESCC) progression remain to be elucidated. An integrated bioinformatics analysis was performed to identify candidate genes in ESCC progression based on GSE micro‑ arrays. SHFM1 was found to be profoundly upregulated in ESCC tissues compared with normal tissues and SHFM1 expression was positively associated with poor prognosis . The biological effects of SHFM1 on cell growth, metastasis and immune escape were investigated following depletion or overexpression of SHFM1 in vitro. A xenograft mouse model was established to investigate the effect of SHFM1 on ESCC progression in vivo. SHFM1 overexpression promoted ESCC cell proliferation and migration in vitro as well as tumori‑ genesis in vivo, while SHFM1 knockdown restored those phenotype changes. Additionally, the present study demon‑ strated that the effects of SHFM1 on malignant behaviors of ESCC cells were achieved by activating the NF‑κB signaling accompanied by increased P65 phosphorylation and nuclear translocation. Furthermore, SHFM1 was also found to regu‑ late the sensitivity of cancer cells to natural killer (NK) cells. Specifically, inhibition of SHFM1 enhanced cell‑mediated cell apoptosis and increased NK toxicity, which might involve the  \nCorrespondence to: Dr Zhiyu Wang, Department of Oncology and Immunology, The Fourth Hospital of Hebei Medical University, 12 Jiankang Road, Shijiazhuang, Hebei 050010, P.R.

In conclusion, these findings suggested that SHFM1 probably promoted ESCC progression by activating the NF‑κB pathway and enhancing the resistance of ESCC cells to NK cell cytotoxicity, indicating that SHFM1 may be a promising target for ESCC treatment.  \nIntroduction  \nEsophageal cancer (ESCA) is one of the most prevalent malig‑ nant cancers worldwide and ranks as the sixth commonest cause of death (1) . Esophageal squamous cell carcinomas (ESCC) and adenocarcinoma are two major subtypes of ESCA with broad pathological heterogeneity and together comprise the majority of diagnosed ESCA cases (2) . ESCCis the primary histologic type and accounts for >90% of ESCA (3) . Currently, the primary clinical therapies have focused on the improvement of patient outcomes, including chemotherapy and surgical resection (4) . Extensive tumor cell metastasis remains the primary cause of high mortality and poor prognosis of ESCC (5) . Previous reports demonstrate that cancer immunotherapies have been considered a central tool against cancer in the past few decades (6,7) .
