Androgen and the androgen receptor (AR) have been shown to play critical roles in male fertility. Our previous data demonstrated that mice lacking AR (AR(-/y)) revealed incomplete germ cell development and lowered serum testosterone levels, which resulted in azoospermia and infertility. However, the consequences of AR loss in Leydig cells remain largely(More)
The phosphatidylinositol 3-kinase (PI3K)/Akt pathway controls several important biological functions, such as cell growth regulation, apoptosis, and migration. However, the way in which PI3K/Akt controls androgen receptor (AR)-mediated prostate cancer cell growth remains unclear and controversial. Here, we demonstrate that the PI3K/Akt pathway regulates AR(More)
The effects of IL-6 on prostate cancer cells are well documented yet remain controversial. Some reports suggested that IL-6 could promote prostate cancer cell growth, while others showed that IL-6 could repress prostate cancer cell growth. Here, we systemically examined various IL-6 signaling pathways in prostate cancer cells and found that IL-6 could go(More)
The Fox genes are united by encoding a fork head domain, a deoxyribonucleic acid (DNA)-binding domain of the winged-helix type that marks these genes as encoding transcription factors. Vertebrate Fox genes are classified into 23 subclasses named from FoxA to FoxS. We have surveyed the genome of the amphioxus Branchiostoma floridae, identifying 32 distinct(More)
Androgens and the androgen receptor (AR) play important roles in male fertility, although the detailed mechanisms, particularly how androgen/AR influences spermatogenesis in particular cell types, remain unclear. Using a Cre-Lox conditional knockout strategy, we generated a tissue-specific knockout mouse with the AR gene deleted only in Sertoli cells(More)
OBJECTIVE To examine the potential role of the neutrophil-to-lymphocyte ratio (NLR) for subclassification of localised upper urinary tract urothelial carcinoma (UUT-UC). PATIENTS AND METHODS From 2004 to 2010, 234 patients with localised UUT-UC underwent radical nephroureterectomy (RNU). NLRs were only obtained under afebrile conditions before RNU.(More)
Androgens and the androgen receptor (AR) play important roles in the testes. Previously we have shown that male total AR knockout (T-AR-/y) mice revealed incomplete germ cell development and lowered serum testosterone levels, which resulted in azoospermia and infertility. However, the consequences of AR loss in particular types of testicular cells remain(More)
Although focal myxoid change is a well-recognized feature of solitary fibrous tumor (SFT), predominantly myxoid SFT are exceedingly rare. Reported herein is the case of a 65-year-old man with SFT containing abundant myxoid matrix, arising from the capsule of the right seminal vesicle. To the authors' knowledge this is the first myxoid SFT involving the male(More)
At our clinic we followed 320 renal transplant recipients, 16 of whom developed malignancies within 15 yr. Ten of the 16 malignancies were transitional cell carcinoma (TCC) of the urinary tract. The modalities of treatment included standard nephroureterectomy with bladder cuff removal for upper tract tumor, transurethral resection for superficial bladder(More)
This study tested the hypothesis that exendin-4 and sitagliptin can effectively protect kidney from acute ischemia-reperfusion (IR) injury. Adult SD-rats (n = 48) equally divided into group 1 (sham control), group 2 (IR injury), group 3 [IR + sitagliptin 600 mg/kg at post-IR 1, 24, 48 hr)], and group 4 [IR + exendin-4 10 μm/kg at 1 hr after procedure] were(More)
