目的 不同患者的结直肠肿瘤之间存在明显的肿瘤异质性，同一位结直肠癌患者的肿瘤内部也存在一定的肿瘤异质性，这是肿瘤不同生物学行为的基础，也是放化疗疗效差异及耐药产生的重要原因之一。

A reciprocal feedback loop of IL6 and Stat3 mediates EphA2-promoting nasopharyngeal carcinoma cell i
Objective EphA2 and interleukin-6(IL6)have been implicated in cancer metastasis and stem properties,but the link between EphA2 and IL6 in cancer is unknown.
GOLM1 and HIF1a form a positive inter-regulatory loop to promote the metastasis and sorafenib resist
Objective Solid tumors are characterized by containing poorly vascularized regions(hypoxia)which are typically associated with poor clinical outcomes,like tumor recurrence,metastasis and chemotherapy
目的 鉴定与HNRNPAB表达显著相关的lncRNA 分子,初步探索HNRNPAB-lncRNA 在肝癌发生发展中的调控机制.方法 应用LncRNA 芯片检测肝癌细胞经过HNRNPAB 干扰或过表达质粒转染前后的lncRNA 表达谱,以P<0.05 的统计学差异为标准,筛选HNRNPAB 的潜在下游lncRNA,并在肝癌细胞系、肝癌组织RNA 中验证目标lncRNA 与HNRNPAB 的相关性,通

Objective Extrahepatic metastasis is commonly regarded as a symbol of advanced stage of HCC and accounts for about 10%of HCC patients.According to the Barcelona Clinic Liver Cancer(BCLC)staging system
目的 探索肝细胞癌(HCC)患者行肝切除术后1周的血清甲胎蛋白(AFP)变化情况的预后评估价值。方法 我们收集了符合入组标准的2009-2011 期间在复旦大学附属中山医院初诊为HCC 并行根治性切除术作为首次治疗的598 例患者作为探索队列，记录其术前AFP 水平(AFP0)及术后1 周时的AFP水平(AFP7)并根据如下公式计算AFP 应答情况(AR)∶AR = lgAFP7/lgAFP0(l
目的 乳腺癌是全球女性最常见的恶性肿瘤之一，其中三阴性乳腺癌(TNBC)约占所有乳腺癌的15％到20％.TNBC 由于缺乏特异性的治疗靶点，且更易发生化疗药耐药，因此其临床预后较差.越来越多的证据表明lncRNAs 是TNBC 潜在的预后因素.
Objective To explore the expression of HIC-5 in pancreatic cancer and its effect on the biological behavior of pancreatic cancer and the long-term prognosis in patients with pancreatic cancer surgery.
