A Cortisol-Secreting Adrenal Adenoma Combined With a Micro-Pheochromocytoma: Case Report and Literature Review.

Cushing's syndrome and pheochromocytomas (PCCs) are associated with endocrine hypertension. Cortisol-producing adrenal adenomas are a major cause of Cushing's syndrome. Simultaneous occurrence of cortisol-producing adrenal adenomas and PCCs is rare.

Remitting seronegative symmetrical synovitis with pitting edema syndrome in maintenance hemodialysis.

Introduction: The remitting seronegative symmetrical synovitis with pitting edema syndrome primarily occurs in elderly individuals to represent symptoms of edema, pain, and joint swelling. It could be misdiagnosed in elderly maintenance hemodialysis patients, as hemodialysis patients often present with pain and joint swelling induced by hypervolemia, inflammation, amyloidosis, and/or chronic kidney disease. Here, we describe a maintenance hemodialysis patient with remitting seronegative symmetrical synovitis with pitting edema syndrome.

Usefulness of a novel device to divide core needle biopsy specimens in a spatially matched fashion.

We developed a novel dividing device that can split needle biopsy tissues along longitude axis aiming to achieve definitive molecular-biological and genetical analysis with reference of pathological diagnosis of the side-by-side divided tissue as spatially matched information. The aim of this study was to evaluate the feasibility and potential usefulness of the novel dividing device to provide the appropriate materials for molecular diagnosis. The new device was examined using mouse xenograft tumors.

Abscopal effect of high-dose-rate brachytherapy on pelvic bone metastases from renal cell carcinoma: a case report.

Radiation therapy is considered an optimal partner for immunotherapies. Several pre-clinical studies have demonstrated that regression of distant metastases, at remote non-irradiated sites of the body, termed the "abscopal effect", can be achieved by an appropriate timing and combination of radiation with immunotherapy. However, nearly all pre-clinical and clinical studies evaluating a combination of radiation and immunotherapies have used external beam radiation therapy.

MRGBP promotes AR-mediated transactivation of KLK3 and TMPRSS2 via acetylation of histone H2A.Z in prostate cancer cells.

The androgen receptor (AR) promotes growth of prostate cancer cells by controlling the expression of target genes. This study showed that MRG domain binding protein (MRGBP) accelerated AR-mediated transactivation. We first showed that MRGBP promoted growth of AR-positive prostate cancer cells.

CNPY2 inhibits MYLIP-mediated AR protein degradation in prostate cancer cells.

The androgen receptor (AR) is a ligand-dependent transcription factor that promotes prostate cancer (PC) cell growth through control of target gene expression. This report suggests that Canopy FGF signaling regulator 2 (CNPY2) controls AR protein levels in PC cells. We found that AR was ubiquitinated by an E3 ubiquitin ligase, myosin regulatory light chain interacting protein (MYLIP) and then degraded through the ubiquitin-proteasome pathway.

CNPY2 promoted the proliferation of renal cell carcinoma cells and increased the expression of TP53.

Renal cell carcinoma (RCC) is the most common type of kidney cancer. However, the mechanisms underlying the progression of the disease are not well understood. The data in this report suggest that canopy FGF signaling regulator 2 (CNPY2) is a promoter of RCC progression.

Androgen suppresses testicular cancer cell growth in vitro and in vivo.

Silencing of androgen receptor (AR)-meditated androgen signaling is thought to be associated with the development of testicular germ cell tumors (TGCTs). However, the role of the androgen/AR signal in TGCT development has not been investigated. In this study, we show that the androgen/AR signal suppressed the cell growth of seminomas (SEs), a type of TGCT, in vitro and in vivo.

PAX2 promoted prostate cancer cell invasion through transcriptional regulation of HGF in an in vitro model.

Elucidating the mechanism of prostate cancer cell invasion may lead to the identification of novel therapeutic strategies for its treatment. Paired box 2 (PAX2) and hepatocyte growth factor (HGF) proteins are promoters of prostate cancer cell invasion. We found that PAX2 protein activated the HGF gene promoter through histone H3 acetylation and upregulated HGF gene expression.

Paired box 2 upregulates androgen receptor gene expression in androgen-independent prostate cancer.

Androgen-independent prostate cancer is known as a hormone-refractory disease. Although the androgen receptor (AR) is considered to be a key regulator of androgen-independent prostate cancer progression, the mechanism through which AR gene expression is regulated is not well understood. In the present study, we showed that the AR gene was upregulated by paired box 2 (PAX2) in androgen-independent prostate cancer.

A genetic screen in Drosophila for regulators of human prostate cancer progression.

To uncover the mechanism by which human prostate cancer progresses, we performed a genetic screen for regulators of human prostate cancer progression using the Drosophila accessory gland, a functional homolog of the mammalian prostate. Cell growth and migration of secondary cells in the adult male accessory gland were found to be regulated by paired, N-cadherin, and E-cadherin, which are Drosophila homologues of regulators of human prostate cancer progression. Using this screening system, we also identified three genes that promoted growth and migration of secondary cells in the accessory gland.
