Colorectal cancer (CRC) remains a major public health concern, associated with a high rate of morbidity and mortality. Several factors have been implicated in its occurrence and development, which includes histone chaperones. The role of spty2d1 (spt2)-a novel histone chaperone protein-has rarely been investigated in CRC. Therefore, we demonstrated in this study that spt2 undergoes different genetic alterations in colorectal adenocarcinoma datasets and that it was associated with the proliferation of colon carcinoma. Spt2 silencing can reduce the ability of proliferation and increase the rate of apoptosis of LoVo cells. Regarding the overall survival associated with spt2, only the quartile disease-free survival of colon adenocarcinoma (COAD) was found to be statistically significant, while that of rectum adenocarcinoma (READ) was not. The positive (+++) expression of spt2 was correlated with a deeper invasion depth in colorectal adenocarcinoma, and this effect was more pronounced in COAD. These data collectively suggest that spt2 can influence the progression and prognosis in some subtypes of colorectal adenocarcinoma. Therefore, we propose spt2 as a potential target for application in enhancing the overall therapeutic efficacy in some specific subtypes of colorectal adenocarcinoma.
