The intracellular distribution of a drug can cause significant variability in both activity and selectivity. Herein, we investigate the mechanism by which the anti-cancer agents, di-2-pyridylketone 4,4-dimethyl-3-thiosemicarbazone (Dp44mT) and the clinically trialed, di-2-pyridylketone 4-cyclohexyl-4-methyl-3-thiosemicarbazone (DpC), re-instate the efficacy of doxorubicin (DOX), in drug-resistant P-glycoprotein (Pgp)-expressing cells. Both Dp44mT and DpC potently target and kill Pgp-expressing tumors, while DOX effectively kills non-Pgp-expressing cancers...

BACKGROUND: Although there is no agreement on a definition of elderly, commonly an age cutoff of ≥65 or 75 years is used. Nowadays most of malignancies requiring surgical treatment are diagnosed in old population. Comorbidities and frailty represent well-known problems during and after surgery in elderly patients. Minimally invasive surgery offers earlier postoperative mobilization, less blood loss, lower morbidity as well as reduction in hospital stay and as such represents an interesting and validated option for elderly population...

The human FAD-dependent oxidoreductase domain containing 1 (FOXRED1) protein is reported as an assembly factor which promotes the correct assembly and stability of mitochondrial Complex I (CI). Alterations of mitochondrial CI might cause tumorigenesis and metastasis, but it's molecular mechanisms remain unclear. In this study, we selected 145 cases of colorectal cancer for immunohistochemistry to explore the role of FOXRED1 played in the tumor progression of colorectal cancer. The relationship between FOXRED1 expression and clinicopathological features of colorectal cancers was evaluated...

Accumulating evidence suggests that aberrantly expressed microRNAs (miRNAs) contribute to the initiation and progression of human cancers. However, the underlying function of miR-193b in colorectal cancer (CRC) remains largely unexplored. Herein, we demonstrate that miR-193b is significantly down-regulated in CRC tissues compared with their normal counterparts. Kaplan-Meier analysis revealed that decreased miR-193b expression was closely associated with the shorter overall survival of patients with CRC. Through gain-and loss-of-function studies, we showed that miR-193b significantly suppressed CRC cell proliferation and invasion...

Preoperative radiotherapy or chemoradiotherapy has become a standard procedure for treatment of patients with locally advanced colorectal cancer (CRC). However, patients' responses to treatment are different and personalized. MicroRNAs (miRNAs) are promising biomarkers for predicting personalized responses. In this study, we collected 30 publicly reported miRNAs associated with chemoradiotherapy of CRC. We extracted 46 differentially expressed miRNAs from samples of responders and non-responders to preoperative radiotherapy from the Gene Expression Omnibus dataset (Student's t test, p-value < 0...

Cyclin B1 is a key mitotic cyclin in the G2-M phase transition of the cell cycle and is overexpressed in various malignant tumors. Numerous studies have reported contradictory evidences of the correlation between cyclin B1 expression and prognosis in human solid tumors. To address this discrepancy, we conducted a meta-analysis with 17 published studies searched from PubMed and Medline. Cyclin B1 overexpression was significantly associated with poor 3-year overall survival (OS) (OR = 2.05, 95% CI = 1.20 to 3...

Cortactin (CTTN) is overexpressed in various tumors, including head and neck squamous cell carcinoma and colorectal cancer (CRC), and can serve as a biomarker of cancer metastasis. We observed that CTTN promotes cancer cell proliferation in vitro and increases CRC tumor xenograft growth in vivo. CTTN expression increases EGFR protein levels and enhances the activation of the MAPK signaling pathway. CTTN expression also inhibits the ubiquitin-mediated degradation of EGFR by suppressing the coupling of c-Cbl with EGFR...
