Project description:High-cell density/confluency leads to contact inhibition of proliferation, as seen in the majority of epithelial cells, and is associated with the initiation of differentiation. To determine potential effect of In this regard, we analyzed transcriptomes using RNAseq, then performed a large-scale expression profiling of T-MSCs and performed a comparison between un-differentiated T-MSCs and T-MSC-PTHCs. Genes with a mean fold change of > 1.5 (T-MSCs vs. T-MSC-PTHCs) with p < 0.05 were analyzed using gene ontology enrichment analysis.RNAseq analysis showed that total of 228 genes were found to be significantly changed. Of them, the genes involved in the proliferation contributed 28% (total count of 63 genes) was the largest of the altered gene population followed by the genes involved in neurogenesis (30 counts; 13%) and extracellular matrix (16 counts; 7%). Among the genes in differentiation, WNT2 showed the highest fold-increase (2.8-fold) in the T-MSC-PTHCs compared to un-differentiated T-MSCs. When KEGG pathway analyses were performed, we found WNT signaling and stem cell pluripotency-regulating pathways as the pathways, where the WNT2 was involved in. This indicates that the differentiation of the T-MSCs could have induced through both of these pathways.

Project description:Primary hyperparathyroidism is a common endocrine disorder frequently affecting postmenopausal women. In this study we have investigated expression of the prolactin receptor (PRLr) in a panel of 37 sporadic parathyroid tumours, as well as functionality in vitro in cultured parathyroid tumour cells. High levels of the prolactin receptor gene (PRLR) transcripts were demonstrated in parathyroid tissues as compared to other reference tissues and breast cancer cells. PRLr products of 60/70 kDa were highly expressed in all parathyroid tumours. In addition varying levels of the 80 kDa PRLr isoform, with known proliferative activity, were demonstrated. In parathyroid tumours PRLr immunoreactivity was observed in cytoplasm in all cases and in addition in the plasma membrane (n = 12) or enlarged lysosomes (n = 4). In normal parathyroid rim PRLr was expressed in cytoplasm and granulae. In in vitro studies of short-term cultured human parathyroid tumour cells prolactin stimulation was associated with transcriptional changes in JAK/STAT, RIG-I like receptor and type II interferon signaling pathways as documented by gene expression profiling. Moreover, PRLR gene expression in parathyroid tumors was significantly inversely correlated with plasma total Ca2+ levels. In conclusion, the prolactin receptor was found highly abundant in human parathyroid gland, parathyroid tumours, correlated with patient Ca2+ levels and functionally responsive to physiological levels of prolactin. These findings suggest a role for the prolactin receptor in human parathyroid adenomas.

These findings suggest a role for the prolactin receptor in human parathyroid adenomas. Expression profiling was done in parathyroid adenomas subjected to prolactin treatment in culture. In addition, corresponding paraffin sections were obtained for verification of PRLr expression by immunohistochemistry. 200 mg/L prolactin (recombinant humanM-BM- prolactin, Cat. No. JM-4687-50, MBL Woburn, MA) was added to 1M-CM-^W 10^6 attached parathyroid tumour cells. Cells were harvested using RNAlater (QIAGEN) and homogenized with QIAshredder for RNA extraction after 3 h and 24 h in culture, respectively. Negative controls were collected in parallel with each case at the same time points. RNA was extracted using QIA Cube, and quality assessed with Bioanalyser and Nanodrop. Expression array profiling and data analysis was done at the KI core facility Bioinformatics and Expression Analysis (BEA, Novum, Huddinge) using the Affymetrix platform and the TITAN ST 1.1 array. A total of 16 samples were analysed including 4 parathyroid adenomas cultured for 3 h or 24 h in the presence of prolactin plus control samples cultured in parallel without prolactin.

Project description:Bovine chondrocyte-seeded and mesenchymal stem cell (MSC)-seeded agarose were cultured for 28 days in chemically defined media containing 10 ng/mL TGF-beta3. Chondrogenic differentiated MSCs were compared to chondrocytes at this timepoint and to undifferentiated MSCs harvested at day 0.

Project description:Transcriptional profiling of genes expressed in normal parathyroid glands (Normal) and adenomatous parathyroid glands from patients with primary hyperparathyroidism (PHPT). Stratagen Human Refernece RNA, pooled from 10 human cell lines, was used to identify genes, which are specifically expressed or suppressed in parathyroid tissue. Comparison between normal and tumor parathyroids shows genes that might be involved in hyperproliferation and PTH hypersecretion in tumors.

Project description:We genetically characterized parathyroid adenomas with large glandular weights, for which independent observations suggest pronounced clinical manifestations. Large parathyroid adenomas (LPTAs) were defined as the 5% largest sporadic parathyroid adenomas identified among the 590 cases operated on in our institution during 2005-2009. The LPTA group showed a higher relative number of male cases and significantly higher levels of total plasma and ionized serum calcium (P <0.001). Further analysis of 21 LPTAs revealed low MIB-1 proliferation index (0.1-1.5%), MEN1 mutations in 5 cases and one HRPT2 mutation. Total or partial loss of parafibromin expression was observed in 10 tumors, two of which also showed loss of APC expression. Using array-CGH, we demonstrated recurrent copy number alterations most frequently involving loss in 1p (29%), gain in 5 (38%) and loss in 11q (33%). Totally 21 minimal overlapping regions were defined for losses in 1p, 7q, 9p, 11 and 15q, and gains in 3q, 5, 7p, 8p, 16q, 17p and 19q. In addition, 12 tumors showed gross alterations of entire or almost entire chromosomes, most frequently gain of 5 and loss of 11. While gain of 5 was the most frequent alteration observed in LPTAs, it was only detected in a small proportion (4/58 cases, 7%) of parathyroid adenomas. A significant positive correlation was observed between parathyroid hormone level and total copy number gain (r = 0.48, P = 0.031). These results support that LPTAs represent a group of patients with pronounced parathyroid hyperfunction and associated with specific genomic features. We applied high-resolution array-CGH to assess copy number alterations (CNAs) in 21 tumors representing the 5% largest sporadic parathyroid adenomas in our institution.

Project description:Pulmonary hypertension (PH) is an incurable right heart failure disease. Parathyroid hormone (PTH) is secreted from the parathyroid gland and plays a crucial role in calcium homeostasis. PTH also acts on the cardiovascular system and affects cardiovascular prognosis. We assessed whether the regulation of PTH affected PH in a hypoxia (Hx)-induced PH mouse model. PTH treatment exacerbated right ventricular hypertrophy and right ventricular systolic pressure in Hx mice. Our data showed how is PTH effected for PH model murine lung.
