Project description:β-cell specific IFT88 knock-out mice recapitulate human diabetes with impaired insulin secretion and altered islet hormone paracrine regulation. To examine the signaling pathways regulating islet cell function, we subjected protein lysates of whole islets from control and IFT88 knockout mice to a commercial phospho-antibody array analysis (Full Moon Bio, Inc). Samples were probed against 1318 site-specific and phospho-specific antibodies with 2 replicates per antibody on 76 x 25 x 1mm glass slides.

Project description:Deglycosylated-leucine-rich α-2-glycoprotein1 (DG-LRG1) as well as LRG1 was discovered to promote angiogenesis under diabetes mellitus condition through TGF-β independent binding to endoglin. To examine the signaling pathways triggered by DG-LRG1, we subjected whole-cell protein lysates of control and DG-LRG1 treated HUVECs to a Phospho Explorer antibody array analysis using commercial antibody array assay kit (Full Moon Biosystems, Inc.). Samples were probed against 1318 site-specific and phospho-specific antibodies with two replicates per antibody printed on a coated glass microscope slide. Phospho Explorer antibody array experiments and analyses were performed as a custom service by E-Biogen (Ebiogen Inc., Seoul, Republic of Korea).

Project description:Male mice on a homogenous C57BL6/J genetic background were sacrificed at 11 to 13 weeks of age by cervical dislocation. Kidneys were immediately harvested, flash frozen in liquid nitrogen and stored at -80°C until use. Animal handling was in accordance with guidelines approved by the European Molecular Biology Laboratory (EMBL). Organ sections (thickness 30 µm) were prepared in a Cryostat (Leica Biosystems, Leica CM3050 S) set to -20 °C and deposited onto SuperFrost glass slides (Carl Roth, H880); the glass slides were pre-cooled to -20°C in the cryostat. ~10 sections were placed on a glass slide, and a total of around 150 sections were prepared for each sample per mouse. Tissue sections on glass slides were then transferred onto metal plates placed on dry ice. The tissue sections were exposed to 1 J/cm2 of 254 nm UV light in a XL 1500 UV Spectrolinker (Spectronics Corporation) and subjected to eRIC (PMID: 30352994). The proteins captured by eRIC were separated by gel electrophoresis, divided into 7 fractions of defined mass, and identified by MS to determine their distribution across the fractions. Crosslinking to other proteins should shift the signal to higher mass fractions. The analyses were conducted in triplicate.

Project description:Male mice on a homogenous C57BL6/J genetic background were sacrificed at 11 to 13 weeks of age by cervical dislocation. Brain, kidneys and liver were immediately harvested, flash frozen in liquid nitrogen and stored at -80°C until use. Animal handling was in accordance with guidelines approved by the European Molecular Biology Laboratory (EMBL). Organ sections (thickness 30 µm) were prepared in a Cryostat (Leica Biosystems, Leica CM3050 S) set to -20 °C and deposited onto SuperFrost glass slides (Carl Roth, H880); the glass slides were pre-cooled to -20°C in the cryostat. ~10 sections were placed on a glass slide, and a total of around 150 sections were prepared for each sample per mouse. Tissue sections on glass slides were then transferred onto metal plates placed on dry ice. The tissue sections were exposed or not to 1 J/cm2 of 254 nm UV light in a XL 1500 UV Spectrolinker (Spectronics Corporation) and subjected to eRIC to determine the RNA-bound proteome. eRIC eluates obtained from the respective organs of two mice were combined per independent experiment. The analyses were conducted in duplicate for each organ studied. For the no crosslink controls, organ sections from four mice were pooled to generate one unique no crosslink eRIC sample per organ studied.

Poly(A) RNA-depleted supernatants obtained after two consecutive rounds of eRIC were stored at -80ºC and then used as input for the column-based guanidinium thiocyanate-phenol-chloroform extraction of ribonuleoprotein (RNP) complexes, applying an adaptation of the 2C method (PMID: 30035255). Four independent irradiated samples were employed. For the non-irradiated control, organ sections from four mice were pooled to generate one non-crosslink sample. 40 µg of captured RNA per sample were employed.

Project description:Expression levels of proteins and phosphoproteins, covering major cancer signaling pathways with a special focus on breast cancer biology, were obtained for a series of 109 breast cancer tumor specimens with positive estrogen receptor status. Tumor specimens from patients diagnosed with primary invasive breast carcinoma were collected at the time of surgery between 2008 and 2010 at the Department of Gynecology and Obstetrics / National Center for Tumor Diseases Heidelberg. None of the patients had received neoadjuvant therapy. Institutional Review Board approval was received as ethics vote no. S039/2008 and informed consent was obtained from all patients. Tumor specimens were processed within 20 min after surgery. Samples were stored snap frozen at -80M-BM-0C until further use. Only tumor samples with > 70% tumour cells and positive estrogen receptor status (immunoreactive score M-bM-^IM-% 3) as assessed by routine immunohistochemistry were selected for this study (n = 109). Tumor lysates were printed on a series of nitrocellulose coated glass slides and probed with 128 different primary antibodies directed against proteins and phosphoproteins of interest. Primary antibodies were selected to recognize proteins involved in major cancer signaling pathways with a special focus on breast cancer biology.
