Antiapoptotic and Prometastatic Roles of Cytokine FAM3B in Triple-Negative Breast Cancer.

Background: Triple-negative breast cancer (TNBC) is the most aggressive subtype of breast cancer. FAM3B, a secreted protein, has been extensively studied in various types of tumors. However, its function in breast cancer remains poorly understood.

Effect of parathyroidectomy on bone tissue biomarkers and body composition in patients with chronic kidney disease and secondary hyperparathyroidism.

Background/objective: Loss of renal function may induce secondary hyperparathyroidism (s-HPT), which triggers several complications leading to an extreme decline in quality of life and increased mortality in affected patients. We evaluated whether parathyroidectomy (PTx), as surgical treatment for s-HPT, modifies body composition, and hormones involved in the protein-energy metabolism of affected patients.

Subjects/methods: Overall, 30 s-HPT patients were evaluated at two times, before PTx (pre PTx) and 6 months after PTx (post PTx).

Comparison of clinical, biochemical and histomorphometric analysis of bone biopsies in dialysis patients with and without fractures.

Chronic kidney disease-mineral bone disorders (CKD-MBD) are associated with increased risk of fracture. Studies report about 3% of fractures in CKD patients, and these occur earlier than in the general population, namely 16 and 13 years earlier for men and women, respectively. Better understanding of the pathophysiology of fractures would probably contribute to new therapeutic approaches.

Effect of variations in dietary Pi intake on intestinal Pi transporters (NaPi-IIb, PiT-1, and PiT-2) and phosphate-regulating factors (PTH, FGF-23, and MEPE).

Hyperphosphatemia is a common condition in patients with chronic kidney disease (CKD) and can lead to bone disease, vascular calcification, and increased risks of cardiovascular disease and mortality. Inorganic phosphate (P) is absorbed in the intestine, an important step in the maintenance of homeostasis. In CKD, it is not clear to what extent P absorption is modulated by dietary P.

FAM3B/PANDER inhibits cell death and increases prostate tumor growth by modulating the expression of Bcl-2 and Bcl-X cell survival genes.

Background: FAM3B/PANDER is a novel cytokine-like protein that induces apoptosis in insulin-secreting beta-cells. Since in silico data revealed that FAM3B can be expressed in prostate tumors, we evaluated the putative role of this cytokine in prostate tumor progression.

Methods: FAM3B expression was analyzed by quantitative PCR in tumor tissue clinical samples and prostate tumor cell lines.

Glucose metabolism and hepatic Igf1 DNA methylation are altered in the offspring of dams fed a low-salt diet during pregnancy.

A low-salt (LS) diet during pregnancy has been linked to insulin resistance in adult offspring, at least in the experimental setting. However, it remains unclear if this effect is due to salt restriction during early or late pregnancy. To better understand this phenomenon, 12-week-old female Wistar rats were fed a LS or normal-salt (NS) diet during gestation or a LS diet during either the first (LS10) or second (LS20) half of gestation.
