CD133 is a wildly used cancer stem cell marker. The purpose of this study was to explore the significance of CD133 mRNA in human cancers mainly based on The Cancer Genome Atlas (TCGA) database. Bioinformatic analyses were done by using public repositories, including BioGPS, SAGE Genie tools, Oncomine analysis, Regulome Explorer, COSMIC analysis, and Kaplan-Meier Plotter. The main findings in this study were: 1) High CD133 mRNA was correlated with a benign survival rate of gastric cancer and lung cancer; 2) Transmembrane protein 125 (TMEM125) in bladder urothelial carcinoma and intercellular adhesion molecule 2 (ICAM2) in ovarian serous cystadenocarcinoma were closely related to CD133 expression; 3) The location and the topological structure of CD133 protein were not determined by its transcript variant in cancer cells; 4) CD38 and CD200 may be used as novel surface markers for solid cancers...

Epitranscriptomics has gained ground in recent years, especially after the advent of techniques for accurately studying these mechanisms. Among all modifications occurring in RNA molecules, N6-methyladenosine (m⁶A) is the most frequent, especially among mRNAs. m⁶A has been demonstrated to play important roles in many physiological processes and several disease states, including various cancer models (from solid to liquid tumors). Tumor cells' epitranscriptome is indeed disrupted in a way to promote cancer-prone features, by means of up/downregulating m⁶A-related players: the so-called writers, readers and erasers...

Accumulative reports have documented the critical functions of long non-coding RNAs (lncRNAs) in the progression of malignant tumors, including bladder cancer (BCa). LncRNA ARAP1-AS1 was chosen to be the object of this study due to it was significantly upregulated in the BCa samples of TCGA database. qRT-PCR further validated the dysregulation of ARAP1-AS1 in 88 pairs of BCa tissues and six BCa cells. Kaplan Meier analysis was utilized to analyze the prognostic value of ARAP1-AS1 for patients with BCa. To evaluate the oncogenic property of ARAP1-AS1 in bladder cancer, loss-of-function assays were conducted in two BCa cells in which ARAP1-AS1 was expressed highest...

Tumor markers of bladder cancer (BC) have been investigated for many years, but the clinical treatment based on these biomarkers is still unsatisfactory. STK32C, a member of the serine/threonine protein kinase of AGC superfamily, was first found to be highly expressed in brain tissues; however, the role of STK32C in malignant disease has not been determined. Data from TCGA database showed that the STK32C gene is overexpressed in BC and a number of other human tumors. In the current study, immunohistochemistry revealed that high expression of STK32C protein in tumor tissues was significantly associated with poor clinico pathologic features and a short relapse-free survival (RFS) in patients with BC...

Tumor-Infiltrating Lymphocytes (TILs) has been shown to be essential to predict disease outcome in several types of cancers. Moreover, the distribution of cytotoxic T lymphocytes (CD8+) and T cells in general (CD3+) have been used to establish an Immunoscore, as a new cancer prognosticator for survival in colon and lung cancer. In bladder cancer, immune activation has been shown to be associated with genomic subtypes of muscle invasive bladder cancer (MIBC). We sought to evaluate the prognostic impact of these immune cell types in MIBC patients treated with radical cystectomy...

Bladder cancer (BC) remains an aggressive disease with a poor prognosis, especially for patients with metastatic disease who have a limited median overall survival of 14 months. Urothelial carcinomas harbor frequent molecular dysregulations including recurrent mutations and copy number alteration, some of which could be potential therapeutic targets. However, no molecularly targeted agents have been approved to date for the treatment of advanced BC. Gaining new insights into the molecular landscape of BC will be critical to tailor future targeted agents for the treatment of advanced disease...

Identification and characterization of somatic mutations in cancer have important prognostication and treatment implications. Genes encoding the Nuclear factor (erythroid-derived 2)-like 2 (NRF2) transcription factor and its negative regulator, Kelch-like ECH-associated protein 1 (KEAP1), are frequently mutated in cancer. These mutations drive constitutive NRF2 activation and correlate with poor prognosis. Despite its apparent significance, a comprehensive catalogue of somatic NRF2 mutations across different tumor types is still lacking...
