MicroRNA-497-5p Is Downregulated in Hepatocellular Carcinoma and Associated with Tumorigenesis and Poor Prognosis in Patients.

Background: MicroRNAs (miRNAs) have been demonstrated to exhibit important regulatory roles in multiple malignancies, including hepatocellular carcinoma (HCC). hsa-miR-497-5p was reported to involve in cancer progression and poor prognosis in many kinds of tumors. However, the expression and its clinical significance of hsa-miR-497-5p in HCC remain unclear.

High mobility group box 1 protein is methylated and transported to cytoplasm in clear cell renal cell carcinoma.

Background: The high mobility group box 1 (HMGB1) protein is a widespread nuclear protein present in most cell types. It typically locates in the nucleus and functions as a nuclear cofactor in transcription regulation. However, HMGB1 can also localize in the cytoplasm and be released into extracellular matrix, where it plays critical roles in carcinogenesis and inflammation.

A potent chemotherapeutic strategy in prostate cancer: S-(methoxytrityl)-L-cysteine, a novel Eg5 inhibitor.

Docetaxel-based combination chemotherapy remains the predominant treatment for castration-resistant prostate cancer. However, taxane-related drug resistance and neurotoxicity have prompted us to develop substitute treatment strategies. Eg5 (kinesin spindle protein), which is crucial for bipolar spindle formation and duplicated chromosome separation during the early phase of mitosis, has emerged as an attractive target for cancer chemotherapy.

Comparison of tamsulosin with extracorporeal shock wave lithotripsy in treating distal ureteral stones.

Background: Tamsulosin, an alpha-1 receptor antagonist, has been demonstrated effective in promoting distal ureteral stone passage and in reducing pain associated with stone expulsion. This study aimed to evaluate the effect of tamsulosin in comparison with nifedipine and extracorporeal shock wave lithotripsy (ESWL) on the expulsion rate of distal ureteral stones at different sizes.

Methods: We assigned 314 patients to three categories: I, the stone with maximal diameter of 4.
