Lentivirus-mediated RNA interference of clusterin enhances the chemosensitivity of EJ bladder cancer cells to epirubicin in vitro.

Clusterin (CLU) is a glycoprotein that is over-expressed in a number of malignant tumors and has been proven to correlate closely with the chemoresistance of several cancer cells to chemotherapeutic agents. However, the effect of CLU expression on the chemoresistance of bladder cancer to epirubicin remains unknown. In the present study, we aimed to elucidate the role of CLU in the chemoresistance of bladder cancer cells to epirubicin.

[Superficial bladder cancer detection using diffuse reflectance spectral ratio R540/R575 of oxygenated hemoglobin bands].

A low-cost, fast, and noninvasive method for early diagnosis of malignant lesions of mucosa tissue based on diffuse reflectance spectra was applied in the study of the optical biopsy of superficial human bladder cancer. In the present paper, differential diagnosis of superficial human bladder cancer was studied using the diffuse reflectance spectral ratio (R540/R575) of the oxygenated hemoglobin absorption bands at 540 and 575 nm in vitro. Diffuse reflectance spectra for mucosa/submucosa tissues of normal bladder and superficial bladder cancer were measured using a spectrophotometer with an integrating sphere attachment.

[Absorption and scattering characteristics of human benign prostatic hyperplasia tissue with Ti: sapphire laser irradiation in vitro].

The optical properties and their differences of human benign prostatic hyperplasia (BPH) tissues removed using transurethral plasma kinetic resection of the prostate (PKRP) and transurethral vaporization of the prostate (TUVP) at 640, 660, 680, 700, 720, 740, 760, 780, 800, 820, 840, 860 and 880 nm of Ti: Sapphire laser were studied in vitro. The measurements were performed using a double-integrating-sphere setup, and the absorption and scattering properties were assessed using the inverse adding-doubling method. The results of measurement showed that the absorption coefficients and reduced scattering coefficients of BPH tissues removed using PKRP and TURP obviously decreased with the increase in the wavelength for thirteen different laser wavelengths.
