BACKGROUND:C‐X‐C chemokine receptor 4 (CXCR4) and CXCR7 are 7‐transmembrane chemokine receptors of the stroma‐derived factor (SDF‐1). CXCR4, but not CXCR7, has been examined in bladder cancer (BCa). This study examined the functional and clinical significance of CXCR7 in BCa.
METHODS:CXCR4 and CXCR7 levels were measured in BCa cell lines, tissues (normal = 25; BCa = 44), and urine specimens (n =...
BACKGROUND:The transmembrane glycoprotein CD133 (cluster of differentiation 133; also known as Prominin or PROM1) has been described as a potential stem cell marker in colorectal cancer and is associated with higher tumorigenic potential and resistance to radiochemotherapy (RCT). In this study, CD133 expression was evaluated in pre‐RCT tumor biopsies and the corresponding post‐RCT surgical specimens...
BACKGROUND:The active metabolite of vitamin D 1α,25‐dihydroxycholecalciferol (1,25D3) has exhibited broad‐spectrum antitumor activity in xenograft animal models. However, its activity against metastatic disease has not been extensively investigated.
METHODS:Squamous cell carcinoma (SCC) or 1,25D3‐resistant variant SCC‐DR cells were treated with 1,25D3. Actin organization was examined by immunofluorescence...
BACKGROUND:The homeobox gene HOXB7 is overexpressed across a range of cancers and promotes tumorigenesis through varying effects on proliferation, survival, invasion, and angiogenesis. Although published microarray data suggest HOXB7 is overexpressed in pancreatic ductal adenocarcinoma (PDAC), its function in pancreatic cancer has not been studied.
METHODS:HOXB7 message and protein levels were examined...
BACKGROUNDStress‐activated protein kinase (SAPK) interacting protein 1 (SIN1) is essential for early embryonic development and is the key regulator of Akt, which plays an important role in various pathological conditions such as cancer. However, the biological function and clinical significance of SIN1 in hepatocellular carcinoma (HCC) remains unknown.
METHODSReal‐time quantitative reverse‐transcriptase...
BACKGROUNDA previous comparative tissue proteomics study by the authors of the current study led to the identification of caldesmon (CaD) as one of the proteins associated with cervical metastasis of oral cavity squamous cell carcinoma (OSCC). In the current investigation, the authors focused on the potential functions of CaD in patients with OSCC.
METHODSCaD expression was examined in tissue samples...
