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.

Description
We examined the effect pg IGF1 actibation on cellular contractility and migration in SSC osteoblast cells. Based on microarray levels of IGF1 expression, we selected fifteen cases and nine controls spanning from the highest IGF1 expression to the lowest in cases and controls. Subsequently, the pattern of IGF1 expressions in these cells was assessed using high throughput RNA sequencing. Overall design: RNA-seq based gene expression profiling of fifteen SSC osteoblasts and nine control osteoblasts.

Description
RATIONALE: Human rhinovirus infections cause colds and trigger exacerbations of lower airway diseases. OBJECTIVES: To define changes in gene expression profiles during in vivo rhinovirus infections. METHODS: Nasal epithelial scrapings were obtained before and during experimental rhinovirus infection, and gene expression was evaluated by microarray. Naturally acquired rhinovirus infections, cultured human epithelial cells, and short interfering RNA knockdown were used to further evaluate the role of viperin in rhinovirus infections. MEASUREMENTS AND MAIN RESULTS: Symptom scores and viral titers were measured in subjects inoculated with rhinovirus or sham control, and changes in gene expression were assessed 8 and 48 hours after inoculation. Real-time reverse transcription-polymerase chain reaction for viperin and rhinoviruses was used in naturally acquired infections, and viperin mRNA levels and viral titers were measured in cultured cells. Rhinovirus-induced changes in gene expression were not observed 8 hours after viral infection, but 11,887 gene transcripts were significantly altered in scrapings obtained 2 days postinoculation. Major groups of up-regulated genes included chemokines, signaling molecules, interferon-responsive genes, and antivirals. Viperin expression was further examined and also was increased in naturally acquired rhinovirus infections, as well as in cultured human epithelial cells infected with intact, but not replication-deficient, rhinovirus. Knockdown of viperin with short interfering RNA increased rhinovirus replication in infected epithelial cells. CONCLUSIONS: Rhinovirus infection significantly alters the expression of many genes associated with the immune response, including chemokines and antivirals. The data obtained provide insights into the host response to rhinovirus infection and identify potential novel targets for further evaluation.

Description
The whole-genome oligonucleotide microarray analysis gives an opportunity for studying the unidentified gene expression background of the idiopathic and H.pylori related gastric erosive alterations. Using microarrays we compared the whole genome gene expression profile of HP+ and HP- gastric erosions and normal adjacent mucosa to explain the possible role and response to HP infection and to get morphology related mRNA expression patterns.

The major type of protein arginine methyltransferase is PRMT1. Since the growth of embryos from Prmt1/ mice was arrested shortly after implantation, PRMT1 must play a critical role in early mouse development.

Description
While activation of canonical NF-?B signaling through the IKK complex is well studied, few regulators of NIK-dependent non-canonical p52 nuclear translocation have been identified. We discovered a novel role for cyclin dependent kinase 12 (CDK12) in transcriptionally regulating the non-canonical NF-?B pathway. High-content phenotypic screening identified a novel compound, 919278, which inhibits lymphotoxin ß receptor (LTßR)- and FN14-dependent p52 nuclear translocation, but not TNFa receptor (TNFR)-mediated, canonical NF-?B p65 nuclear translocation. Chemoproteomics identified cyclin dependent kinase 12 (CDK12) as the target of 919278. CDK12 inhibition by 919278, THZ1, or siRNA knock down all affect similar global transcriptional changes and prevent LTßR and FN14-dependent MAP3K14 (NIK) mRNA induction and subsequent protein accumulation. In addition, 919278 and THZ1 treatment reduce RNA Pol II CTD phosphorylation. This powerful approach of coupling a phenotypic screen with chemoproteomics revealed a novel regulatory pathway of the non-canonical NF-?B pathway that could serve as a therapeutic target in autoimmunity and cancer. Overall design: There are TWEAK stimulated and unstimulated conditions, 4hr and 24hr time points. 7 treatments (DMSO, BIO0702697, BIO0919278, BIO032202, NTsiRNA, siRNAs523626, siRNAs523629) in duplicates. In total, 56 sample were sequenced and analyzed.
