Project description:Esophageal squamous cell carcinoma (SCC) is frequently diagnosed at advanced stage and associated with poor prognosis. This study aimed to identify differentially expressed genes for further evaluated as biomarkers for predicting survival of the patients. Five paired of cancerous and normal tissues from esophageal SCC patients were subjected to cDNA microarray analysis and one of these differentially expressed genes, NEK6, was further verified in esophageal SCC tissues. The data showed 444 up-regulated genes and 918 down-regulated genes in tumor tissues (2 folds as a cut-off value). qRT-PCR data showed that 20 of 30 (66.7%) increased levels of NEK6 mRNA in cancerous tissues compared to that of distant normal tissues, while immunohistochemical data showed that 49/94 (52.13%) of the archived esophageal SCC tissues expressed higher levels of NEK6 than that of normal tissues. NEK6 expression was associated with depth of tumor invasion (P=0.005), lymph node metastasis (P=0.018), and advanced clinical tumor stages (P=0.004) of these 94 patients. Kaplan Meier curve showed that the overall survival of NEK6-positive patients was much lower than those of NEK6-negative patients (P<0.001). The median survival of NEK6-positive patients was 23 months, whereas the median survival of NEK6-negative patients was 64 months. The cumulative 5-year survival rate of NEK6-positive patients was 14.3% (7/49), whereas the rate of NEK6-negative patients was 64.4% (29/45). Multivariate analysis showed that N classification (P=0.002) and NEK6 expression (P<0.001) were independent predictors for esophageal SCC patients. These data demonstrated that NEK6 expression may serve as an independent prognostic indicator for patients with esophageal SCC. Gene expression in five paired of cancerous and normal tissues from esophageal SCC patients were measured using Human Genome 4x44K v2 Microarray.

Project description:Esophageal cancer presents significant challenges due to limited treatment options and poor prognosis, particularly in advanced stages. Dysregulated long non-coding RNAs (lncRNAs) are implicated in cancer progression and treatment resistance. This study investigated the roles of dysregulated lncRNA, identified through lncRNA-seq, and its downstream target gene in esophageal squamous cell carcinoma（ESCC).

Project description:The human genome encodes two proteins closely related to transketolase (TKT), transketolase-like protein 1 and 2 (TKTL1 and TKTL2). TKTL1 shares 61% amino acid sequence identity with TKT. More and more evidence suggests a role for TKTL1 in proliferation or cell cycle regulation. Indeed, TKTL1 is overexpressed in various cancers and is correlated with poor prognosis in colon, urothelial, gastric, and lung cancers as well as in ocular adnexa carcinomas, rectum carcinomas, and laryngeal squamous cell carcinomas. Increased TKTL1 levels also correlate with esophageal squamous cell carcinoma metastasis and increased resistance against cisplatin chemotherapy in nasopharyngeal carcinomas. Moreover, TKTL1 overexpression promotes cell proliferation and enhanced tumor growth; in contrast, TKTL1 down regulation attenuates the proliferation of various types of cancer cells. However, the cellular functions and regulatory machineries of TKTL1 are still largely unknown. Through this proteomic analysis, we defined the protein-protein interaction map for the TKTL1 and uncovered the novel regulating function of TKTL1 in regulating TKT transketolase activity.

Project description:Human hypopharygeal squamous cell carcinoma (HSCC) is a common head and neck cancer with a poor prognosis in advanced stages. Determining genes associated with transferring in HSCC could provide new targets and therapeutic strategies. We performed single-cell RNA sequencing of hypopharyngeal carcinoma and lymphoid metastases from five patients with hypopharyngeal squamous cell carcinoma.
