摘　　要：BACKGROUND Colorectal cancer(CRC)is one of the most frequently encountered malignant tumors in clinical settings.Proteins encoded by the testis-expressed gene 14(TEX14)are imperative for spermatogenesis,necessitating intercellular bridges between germ cells.Anomalous expression of TEX14 has also been associated with the proliferation and differentiation of certain tumor cells.Recombinant A disintegrin and metalloprotease 17(ADAM17)is known as a membrane-bound protease that regulates cellular activities and signal transduction by hydrolyzing various substrate proteins on the cell membrane.We hypothesize that TEX14 and ADAM17 may serve as potential biomarkers influencing the staging,invasion,and metastasis of CRC.AIM To probe the correlation between TEX17 and ADAM17 profiles in the CRC tissues of elderly patients and their association with CRC staging,invasion,and metastasis.METHODS We gathered data from 86 elderly patients diagnosed pathologically with CRC between April 2020 and December 2023.For each patient,one sample of cancer tissue and one sample of adjacent normal tissue were harvested.Real-time fluorescence quantitative PCR measured the mRNA profiles of TEX14 and ADAM17.Immunohistochemistry ascertained the positivity rates of TEX14 and ADAM17 expressions.Clinical pathological features of neoplasm staging,invasion,and metastasis were collected,and the association between TEX14 and ADAM17 expressions and clinical pathology was evaluated.RESULTS The mRNA and expression profiles of TEX14 and ADAM17 were significantly elevated in CRC tissues.The positivity rates of TEX14 and ADAM17 proteins in CRC tissues were 70.93%and 77.91%,respectively.There were no significant differences in age,sex,pathological type,and tumor diameter between TEX14 and ADAM17-positive and-negative patients.Patients with higher tumor differentiation degree,deeper infiltration and TNM stages ranging from III to IV exhibited higher positivity rates of TEX14 and ADAM17.Patients with lymph node metastasis and distant metastasis showed higher po
