Long Noncoding RNA SNHG12 Promotes Prostate Tumor Occurrence and Progression via AKT Regulation.

The small nucleolar RNA host gene 12 (SNHG12) has been reported to play an important role in the tumorigenesis and progression of PCa, but the functional underlying mechanism has not been studied clearly. We detected the expression level of SNHG12 in PCa tissues and matched adjacent normal tissues that were collected from 85 patients. Then, colony formation assays, MTT experiments, and flow cytometry were used to examine the effect of SNHG12 on proliferation, cell cycle distribution, and apoptosis of DU145 cells.

Laparoscopic T-Plasty for the Treatment of Refractory Bladder Neck Stenosis.

Preliminary results of a case series on refractory bladder neck stenosis treated with laparoscopic T-plasty are presented in this article. This study retrospectively identified nine patients with refractory bladder neck stenosis aged 60 to 80 years between May 2016 and December 2017, who had undergone laparoscopic T-plasty. All patients presented voiding difficulty and failed after two or more prior endoscopic treatments.

Selective Castration-resistant Prostate Cancer Photothermal Ablation With Copper Sulfide Nanoplates.

Objective: To explore new therapies for castration-resistant prostate cancer to improve patients' quality of life and extend life.

Materials And Methods: The synthesis, morphology analysis, phase analysis, spectral analysis, and photothermal conversion test were referenced to our previous articles. Then near-infrared light-driven copper sulfide (CuS) nanoplates to inhibit the growth of prostate cancer cells in vivo and in vitro was carried out.

Inhibition of histamine receptor H3R suppresses prostate cancer growth, invasion and increases apoptosis via the AR pathway.

Histamine h3 receptor (H3R) is expressed in numerous types of tumor and is associated with tumor cell proliferation, migration and invasion. However, whether H3R is expressed in prostate cancer remains unknown. Therefore, the expression and function of H3R in prostate cancer was investigated.

MicroRNA-21 Regulates the Proliferation, Differentiation, and Apoptosis of Human Renal Cell Carcinoma Cells by the mTOR-STAT3 Signaling Pathway.

MicroRNA-21 (miRNA-21), a kind of short, noncoding RNAs, functioned as a tumor marker and was upregulated in renal cell carcinoma (RCC). However, the underlying mechanisms of miRNA-21 in RCC were uncertain. Therefore, the effects and mechanisms of miRNA-21 on the proliferation, differentiation, and apoptosis of cultured human RCC cells were further investigated in this study.

Curcumin induces cell cycle arrest and apoptosis of prostate cancer cells by regulating the expression of IkappaBalpha, c-Jun and androgen receptor.

Curcumin possesses chemopreventive properties against several types of cancer, but the molecular mechanisms by which it induces apoptosis of cancer cells and inhibits cancer cell proliferation are not clearly understood. To evaluate the antitumor activity of curcumin for prostate cancer, we used an androgen dependent LNCaP prostate cancer cell line and an androgen independent PC-3 prostate cancer cell line as experimental models. We treated these cells with curcumin and then evaluated the effects of curcumin on cell cycle profiling and apoptosis, as well as the activation of NF-kaapaB and c-jun in these cells.

Oral complications after lingual mucosal graft harvesting for urethroplasty in 110 cases.

OBJECTIVE • This study was to evaluate donor-site complications of lingual mucosal graft harvesting for substitution urethroplasty. PATIENTS AND METHODS • 110 patients with anterior urethral strictures or hypospadias underwent lingual mucosal grafts (LMGs) urethroplasty. Dual LMGs were harvested from both sites separately or a long mucosal graft was harvested from one side to other side of tongue in 29 patients (group one); a shorter mucosal graft was harvested from one side of tongue in 81 patients (group two).

Construction of cavernosum smooth muscle using umbilical artery smooth muscle cells seeded on acellular corporal collagen matrices.

The objective of this study was to investigate the feasibility of tissue engineering of corpus cavernosal smooth muscle. Acellular corporal collagen matrices (ACCMs) were obtained from the penis of adult rabbits by a cell removal procedure. ACCMs were implanted into the back muscles of allogenic rabbits to investigate the resulting immunological reaction.

[Expression of Omi/HtrA2 UP-regulated in the spermatozoa of chronic bacterial prostatitis patients].

Objective: To determine the expression of Omi/HtrA2 in the spermatozoa of chronic bacterial prostatitis patients and explore the potential mechanism of chronic prostatitis inducing male infertility.

Methods: Forty-one patients diagnosed as suffering from chronic prostatitis were included, and so were 12 healthy normal men as controls. Spermatozoa in the semen were purified by Percoll gradient technique to separate the seminal plasma and other round cells.

Urethral substitution using autologous lingual mucosal grafts: an experimental study.

Objective: To investigate the feasibility of urethral substitution using free lingual mucosa grafts (LMGs) in a dog model.

Materials And Methods: The study included 10 female mongrel dogs in which a 4 x 1 cm(2) section of urethral mucosa was excised. The defect was immediately repaired with a size-matched free LMG harvested from the inferior lateral surface of the tongue.

Immunohistochemical analysis of Omi/HtrA2 expression in prostate cancer and benign prostatic hyperplasia.

The serine protease Omi/HtrA2 is released from mitochondria into the cytosol after apoptotic stimuli, inducing apoptosis in a caspase-independent manner through its protease activity and in a caspase-dependent manner by neutralizing the inhibition of inhibitor of apoptosis proteins (IAPs) on caspases. Alteration of apoptosis is essential for cancer development, and cancer cell death by radiation and chemotherapy is largely dependent upon apoptosis. Thus, analysis of the expression status of Omi/HtrA2, a regulator of apoptosis, in cancer tissues is needed for an understanding of cancer development.

[Effects of Omi/HtrA2 on expression of anti-apoptotic protein PED/PEA-15 and apoptosis of prostate cancer cell line PC-3].

Background & Objective: The interaction between pro-apoptotic factors and anti-apoptotic factors is closely related to the genesis and development of tumors. Omi/HtrA2 is a novel gene involved in the regulation of apoptosis. PED/PEA-15 is a widely expressed anti-apoptotic protein.

[Time resolution spectrum measurements of the process of photon acting on the silver halide materials].

The silver halide material is a very important optical information material. Silver halide material plays a very imperative role in the development of the information science and technology. The time characters of the photon action process determine the quality of the silver halide material to a great degree.
