研究目的:

皮肤鳞状细胞癌(cSCC)作为最常见的非黑色素瘤皮肤癌,发病率持续攀升,其淋巴结转移与远处转移风险严重威胁患者生存。然而当前cSCC的致病机制尚未完全阐明,缺乏特异性早期诊断标志物及有效治疗靶点,亟需揭示其核心驱动因子及干预策略。我们前期工作发现BubR1在cSCC组织中特异性高表达(免疫组化阳性率86.7%,P<0.001),敲低后显著抑制细胞增殖(CCK-8检测72h抑制率达39.8%),并通过IP-MS筛选鉴定出AP2-β为BubR1关键互作蛋白。基于此我们提出科学假说:BubR1可能通过其激酶结构域促进胰岛素受体(INSR)内吞,经下游信号通路异常激活增强cSCC细胞代谢活性与增殖能力,进而驱动肿瘤进展。本项目将深入解析BubR1激酶活性介导的INSR内吞在cSCC发生发展中的分子机制,并据此开发整合生物标志物与病理表型的预后评估体系,为临床精准诊疗策略提供科学依据,最终改善患者生存结局。  

Objectives of Study:

As the most common non-melanoma skin cancer, the incidence of cutaneous squamous cell carcinoma (cSCC) continues to rise, and the risk of lymph node metastasis and distant metastasis is a serious threat to patient survival. However, the pathogenic mechanism of cSCC has not yet been fully elucidated, and there is a lack of specific early diagnostic markers and effective therapeutic targets, so there is an urgent need to reveal its coredrivers and intervention strategies. In our previous work, we found that BubR1 was specifically highly expressed in cSCC tissues (immunohistochemistry positivity rate of 86.7%, P<0.001), and significantly inhibited cell proliferation after knockdown (CCK-8 assay inhibition rate of 39.8% for 72h), and identified AP2-β as a key interplay protein of BubR1 through IP-MS screening. Based on this, we propose the scientific hypothesis that BubR1 may promote insulin receptor (INSR) endocytosis through its kinase structural domain, and enhance the metabolic activity and proliferation capacity of cSCC cells through the aberrant activation of the downstream si gnaling pathway, which in turn drives tumor progression. This project will analyze the molecular mechanism of INSR endocytosis mediated by BubR1 kinase activity in the development of cSCC, and develop a prognostic evaluation system integrating biomarkers and pathological phenotypes, which will provide a scientific basis for precise clinical diagnosis and treatment strategies

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

一、数据采集 本研究拟在经患者知情同意后,采集6例皮肤鳞状细胞癌患者手术切除的肿瘤组织及癌旁正常组织样本。样本采集过程严格遵守伦理及隐私保护要求,由临床医生在常规手术中获取,不增加患者额外风险。样本将立即编号、脱敏处理并冷冻保存,用于后续RNA测序及分子机制研究。所有临床信息(如年龄、性别、病理类型等)均通过病例系统提取,并在采集时去除姓名、住院号等可识别信息。 二、数据管理 采集的生物样本及测序数据均采用唯一编码进行管理,不含任何可识别个人身份的信息。研究数据将存储于加密的实验室服务器,并仅限项目成员访问。所有实验记录、原始数据及分析结果均建立电子备份并定期更新,确保数据安全与可追溯性。项目结束后,数据将按照机构要求归档保存,任何对外共享或发表的结果均基于去标识化处理后的数据,严格保护受试者隐私。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

I. Data Collection This study intends to collect surgically resected tumor tissue and adjacent normal tissue samples from six patients with cutaneous squamous cell carcinoma, with informed consent from the patients. Sample collection will be conducted by clinicians during routine surgery, strictly adhering to ethical and privacy protection requirements and posing no additional risk to the patients. Samples will be immediately numbered, desensitized, and cryopreserved for subsequent RNA sequencing and molecular mechanism studies. All clinical information (such as age, gender, and pathology) will be extracted from the patient's medical records system, and identifying information such as names and hospitalization numbers will be removed during collection. II. Data Management Collected biological samples and sequencing data will be uniquely coded and managed without any personally identifiable information. Research data will be stored on an encrypted laboratory server, with access restricted to project members. All experimental records, raw data, and analysis results will be electronically backed up and regularly updated to ensure data security and traceability. After the project concludes, data will be archived in accordance with institutional requirements. Any results shared or published externally will be based on de-identified data to strictly protect the privacy of the subjects.
