RESUMEN
A previous study reported the decreased expression of long non-coding RNA mortal obligate RNA transcript (lncRNA MORT) in 16 types of cancer, while the functionality of lncRNA MORT in cancer biology remains unknown. Therefore, the present study was conducted to characterize the functionality of lncRNA MORT in prostate carcinoma, a common cancer type worldwide. lncRNA MORT expression level was downregulated in tumor tissues compared with that in the adjacent healthy tissues of patients with prostate carcinoma. Expression of lncRNA MORT in tumor tissues was influenced by tumor size, but not by tumor metastasis. Overexpression of lncRNA MORT inhibited glucose uptake and glucose transporter 1 (GLUT-1) expression in prostate carcinoma cell lines; GLUT-1 overexpression upregulated glucose uptake and attenuated the effects of lncRNA MORT overexpression on glucose uptake, but did not significantly affect the expression of lncRNA MORT. Overexpression of lncRNA MORT inhibited, while GLUT-1 overexpression promoted the proliferation of prostate carcinoma cells. In addition, GLUT-1 overexpression attenuated the effects of lncRNA MORT on cell proliferation. Therefore, lncRNA MORT may inhibit cancer cell proliferation in prostate carcinoma by preventing glucose uptake.
RESUMEN
OBJECTIVE: To study the clinical characteristics and treatment of Fournier's gangrene. METHODS: We retrospectively analyzed the clinical data of 23 cases of Fournier's gangrene, all with flare and pains in the scrotum and penis and different degrees of involvement of the scrotum, penis, perianal area, perineum, inguinal and lower extremities. The patients were treated by early debridement, incision-drainage, anti-infection and hyperbaric oxygen therapy, respectively. Scrotoplasty was performed for 11 of the cases, penile and scrotal dermatoplasty for 7, and penile amputation and urethral fistulation for 2 with penile necrosis. One of the cases underwent suprapubic cystostomy, and another 1 received colostomy. RESULTS: Twenty of the patients were recovered and 3 (1 with diabetes and 1 with AIDS) died after surgery. CONCLUSION: Fournier's gangrene is a fatal disease. Early diagnosis and timely surgical intervention are essential for the management of the disease.
