The incidental finding of renal cysts is a common clinical situation given their high prevalence (~ 50 % after the age of 50) and the continuous improvement of abdomen imaging. Diagnosis is central to appropriately dictate the management of the patient. During the diagnostic work-up, it is important to consider (i) the aspect of the cysts, (ii) their number, (iii) and their location, as well as (iv) the age of the patient and his/her personal and familial medical history, (v) the presence of extra-renal manifestations, (vi) and the renal function (including the urinary sediment). Starting from an atypical clinical case characterized by a rapidly evolving chronic kidney disease associated with bilateral renal cysts, we review the classical diagnostic work-up of kidney cysts. As a conclusion, we propose a diagnostic algorithm including both acquired and hereditary nephropathies. [less ▲]

Vaccinia-H1 Related (VHR) dual-specificity phosphatase, or DUSP3, plays an important role in cell cycle regulation and its expression is altered in several human cancers. In mouse model, DUSP3 deletion prevents neo-angiogenesis and b-FGF-induced microvessel out- growth. Considering the importance of angiogenesis in metastasis formation, our study aimed to investigate the role of DUSP3 in tumour cell dissemination. Using a Lewis Lung carcinoma (LLC) experimental metastasis model, we observed that DUSP3-/- mice devel- oped larger lung metastases than littermate controls. DUSP3-/- bone marrow transfer to lethally irradiated DUSP3+/+ mice was sufficient to transfer the phenotype to DUSP3+/+ mice, indicating that hematopoietic cells compartment was involved in the increased tumour cell dissemination to lung tissues. Interestingly, we found a higher percentage of tumour- promoting Ly6Cint macrophages in DUSP3-/- LLC-bearing lung homogenates that was at least partially due to a better recruitment of these cells. This was confirmed by 1) the pres- ence of higher number of the Ly6Bhi macrophages in DUSP3-/- lung homogenates and by 2) the better migration of DUSP3-/- bone marrow sorted monocytes, peritoneal macrophages and bone marrow derived macrophages (BMDMs), compared to DUSP3+/+ monocytes, macrophages and BMDMs, in response to LLC-conditioned medium. Our study demon- strates that DUSP3 phosphatase plays a key role in metastatic growth through a mechanism involving the recruitment of macrophages towards LLC-bearing lungs. [less ▲]
