Abstract

Background: Sialic acid-bound immunoglobulin lectin 15 (Siglec-15) plays an important role in the development of cancer. However, the association between Siglec-15 expression and clinicopathological characteristics of colorectal cancer (CRC) has not been fully investigated.

Methods: In this present study, a number of bioinformatics analyses were performed to provide an overview and detailed characteristics of Siglec-15. Quantitative real-time polymerase chain reaction (qPCR), western blotting and immunohistochemistry analyses were conducted to characterize the expression of Siglec-15 in CRC. Kaplan-Meier survival and Cox regression analyses were performed to identify the prognostic parameters of CRC.

Results: The results of bioinformatics analyses revealed the expression characteristics and prognostic roles of Siglec-15 in CRC. The data of qCPR, western blotting, and IHC analyses demonstrated that the expression of Siglec-15 in CRC tissues was significantly higher than that in non-cancerous tissues. Moreover, the expression level of Siglec-15 in CRC was significantly associated with lymph node metastasis (p=0.001), TNM stage (p=0.001), and overall survival (p=0.026). COX multi-factor analysis indicated that Siglec-15 expression (p=0.023) and tumor differentiation (p=0.003) were independent prognostic factors for CRC.

Conclusions: Collectively, the data suggested that Siglec-15 expression may serve as a novel prognostic factor and Siglec-15 might be identified as an ideal candidate for immunotherapy in CRC treatment.

新型免疫检查点 Siglec-15 在人类结直肠癌中的表达特征和预后功能。

背景：Sialic酸结合免疫球蛋白凝集素15（Siglec-15）在癌症的发展中起着重要作用。然而，Siglec-15 的表达与结直肠癌（CRC）临床病理特征之间的关联尚未得到充分研究：本研究进行了一系列生物信息学分析，以提供 Siglec-15 的概况和详细特征。本研究对 Siglec-15 的表达进行了一系列生物信息学分析，以提供 Siglec-15 的概况和详细特征，并进行了实时定量聚合酶链反应（qPCR）、免疫印迹和免疫组化分析，以确定 Siglec-15 在 CRC 中的表达特征。通过卡普兰-梅耶生存分析和考克斯回归分析确定 CRC 的预后参数：结果：生物信息学分析结果显示了 Siglec-15 在 CRC 中的表达特点和预后作用。qCPR、Western印迹和IHC分析数据表明，Siglec-15在CRC组织中的表达明显高于非癌组织。此外，Siglec-15在CRC中的表达水平与淋巴结转移（p=0.001）、TNM分期（p=0.001）和总生存率（p=0.026）有明显相关性。COX多因素分析表明，Siglec-15的表达（p=0.023）和肿瘤分化（p=0.003）是CRC的独立预后因素：总之，这些数据表明，Siglec-15的表达可作为一种新的预后因素，Siglec-15可能被确定为CRC治疗中免疫疗法的理想候选者。

期刊介绍： HISTOLOGY AND HISTOPATHOLOGY is a peer-reviewed international journal, the purpose of which is to publish original and review articles in all fields of the microscopical morphology, cell biology and tissue engineering; high quality is the overall consideration. Its format is the standard international size of 21 x 27.7 cm. One volume is published every year (more than 1,300 pages, approximately 90 original works and 40 reviews). Each volume consists of 12 numbers published monthly online. The printed version of the journal includes 4 books every year; each of them compiles 3 numbers previously published online.
