We have previously shown that in addition to the well-known secreted isoform of prostatic acid phosphatase (sPAP), a transmembrane isoform exists (TMPAP) that interacts with snapin (a SNARE-associated protein) and regulates the endo-/exocytic pathways. We have also shown that PAP has 5'-ectonucleotidase and thiamine monophosphatase activity and elicits antinociceptive effects in mouse models of chronic inflammatory and neuropathic pain. Therefore, to determine the physiological role of PAP in a ...[more]

Project description:MyD88 is an important adaptor protein for signal transduction downstream of Toll-like receptors and TACI, receptors for regulation of innate immunity and B cell responses, respectively. The surfaces of oral mucosa are protected from infections by antimicrobial proteins and natural immunoglobulins that are constantly secreted in saliva, serving as principal innate immune defense in the oral cavity. Although MyD88-mediated signaling has a regulatory role in the intestinal mucosal immunity, its specific role in the oral cavity has been remained elusive. To identify the specific roles of MyD88-dependent signaling in gene expression profiles in salivary glands, we performed microarray analysis of the major salivary gland tissues (submandibular gland plus sublingual gland) from control (wild-type C57BL/6) mice and C57BL/6 background Myd88-null mice using Agilent Whole Mouse Genome Oligo Microarrays (8x60K, Design ID 028005). Total RNA was extracted from the major salivary gland tissues (submandibular gland plus sublingual gland) of wild-type and Myd88-null mice using using Trizol reagent (Life Technologies, Rockville, MD, USA) according to the manufacturer's instructions. 100 ng of all RNA samples was used as template to produce Cy3-labeled cRNA. The RNA samples were amplified and labeled using the Low Input Quick Amp Labeling Kit (Agilent Technologies, Palo Alto, USA) following the manufacturerM-bM-^@M-^Ys protocol. Cy3 labeled cRNAs were hybridized overnight (17 hours, 65M-BM-0C) to an Agilent Whole Mouse Genome Oligo Microarrays (8x60K, Design ID 028005) using AgilentM-bM-^@M-^Ys recommended hybridization chamber and oven.Finally, microarrays were washed once with wash buffer 1 for 1 min at RT followed by a second wash with wash buffer 2 for 1 min at 37M-BM-0C and a final wash step with acetonitrile for 30 sec at RT. Fluorescence signals of the hybridized Agilent Microarrays were detected using AgilentM-bM-^@M-^Ys Microarray Scanner System (G2505C, Agilent Technologies). The Agilent Feature Extraction Software (FES 10.7.3.1 ) was used to read out and process the microarray image files.
