Abstract
The present study was done to develop a useful experimental model for analysis of the effects of physiologically active substances on atrophy and regeneration of salivary gland acinar cells. Resection wounds (diameter, 3 mm) were made in the submandibular glands of 8-week-old Wistar rats (n = 24) for histochemical examination on Days 3, 5, 7, 10, 14, and 21 after implantation of a gelatin-based hydrogel sheet. The results showed that the sheet had nearly disappeared by Day 10. Regions around the resection wounds were classified as normal, atrophic, or necrotic. In atrophic regions, acinar cells atrophied after resection, and few acinar cells were observed on Day 7. On Days 5-7, striated and granular ducts resembled duct-like structures. On Day 10, newly formed acinar cells were confirmed by increased periodic acid-Schiff staining, and a greater number of mature cells was present thereafter. In necrotic regions, acinar and ductal cells were destroyed, and scattered enucleated acinar cells and duct-like structures were present, on Day 3; newly formed acinar cells were observed on Day 10. Thus, the experimental model demonstrated atrophy and regeneration of the submandibular gland and enabled analysis of the effects of sustained release of physiologically active substances contained within an implanted sheet.

Abstract
The aim of this study was to determine the localization of aquaporin-5 (AQP5), transforming growth factor-β1 (TGF-β1) and laminin during regeneration of the rat submandibular gland. After duct ligation for 7 days, the regenerating glands were collected on days 0, 1, 3, 7, and 14 after ligation release to study the process of regeneration. Immunohistochemical staining revealed apical expression of AQP5 in many acinar cells, strong expression in intercalated ducts (ICDs) of the normal submandibular gland at Day 14, and strong expression in duct-like structures (DLSs) during regeneration from Day 0 to 7. However, a few AQP5-negative acinar cells were detected during regeneration. At Day 0, immunopositivity for TGF-β1 was detected in connective tissue. At Days 3 and 7 during regeneration, TGF-β1 immunostaining was observed in DLSs, which were surrounded by α-smooth muscle actin-positive thickened myoepithelial cells. Laminin staining was strong in the thickened basement membrane of DLSs at Day 3 during regeneration, but weak around acinar cells at Day 14. These findings suggest that TGF-β1 is involved in the environment around DLSs, myoepithelial cells and laminin, that DLSs have the same functional properties as ICDs, and that AQP5-negative acinar cells may be mucous cells.

Abstract
The laminin-binding integrins, α3β1 and α6β1, are needed for tumor metastasis and their surface expression is regulated by endocytic recycling. β1 integrins share the Rab11 recycling machinery, but the trafficking of α3β1 and α6β1 are distinct by an unknown mechanism. Using a mouse PDX tumor model containing human metastatic prostate cancer, Rab11 family interacting protein 5 (Rab11-FIP5) was identified as a lead candidate for α6β1 trafficking. Rab11-FIP5 and its membrane-binding domain were required for α6β1 recycling, without affecting the other laminin-binding integrin (i.e., α3β1) or unrelated membrane receptors like CD44, transferrin receptor, or E-cadherin. Depletion of Rab11-FIP5 resulted in the intracellular accumulation of α6β1 in the Rab11 recycling compartment, loss of cell migration on laminin, and an unexpected loss of α6β1 recycling in cell-cell locations. Taken together, these data demonstrate that α6β1 is distinct from α3β1 via Rab11-FIP5 recycling and recycles in an unexpected cell-cell location.Implications: Rab11-FIP5-dependent α6β1 integrin recycling may be selectively targeted to limit migration of prostate cancer cells into laminin-rich tissues.

Abstract
Laminin binding integrins α6 (CD49f) and α3 (CD49c) are persistently but differentially expressed in prostate cancer (PCa). Integrin internalization is an important determinant of their cell surface expression and function. Using flow cytometry, and first order kinetic modeling, we quantitated the intrinsic internalization rates of integrin subunits in a single cycle of internalization. In PCa cell line DU145, α6 integrin internalized with a rate constant (kactual ) of 3.25 min-1 , threefold faster than α3 integrin (1.0 min-1 ), 1.5-fold faster than the vitronectin binding αv integrin (CD51) (2.2 min-1 ), and significantly slower than the unrelated transferrin receptor (CD71) (15 min-1 ). Silencing of α3 integrin protein expression in DU145, PC3, and PC3B1 cells resulted in up to a 1.71-fold increase in kactual for α6 integrin. The internalized α6 integrin was targeted to early endosomes but not to lamp1 vesicles. Depletion of α3 integrin expression resulted in redistribution of α6β4 integrin to an observed cell-cell staining pattern that is consistent with a suprabasal distribution observed in epidermis and early PIN lesions in PCa. Depletion of α3 integrin increased cell migration by 1.8-fold, which was dependent on α6β1 integrin. Silencing of α6 integrin expression however, had no significant effect on the kactual of α3 integrin or its distribution in early endosomes. These results indicate that α3 and α6 integrins have significantly different internalization kinetics and that coordination exists between them for internalization. J. Cell.

Abstract
Fibroblast growth factors (FGFs) and their receptors (FGFRs) play important roles in the development of the submandibular gland. Although regeneration of submandibular glands follows a similar process to their development, it is unknown how FGFs and FGFRs are distributed during regeneration of submandibular gland. The aim of this study was to determine the localization of FGFs and FGFRs during such regenerative processes. After 7 days' obstruction, the submandibular glands were collected at days 0, 1, 3, 7, 11 and 14 after duct release to study regeneration. The regenerative processes of the submandibular gland were investigated by immunohistochemistry for FGF-2, 7, 8, 10 and FGFR-1-4. Immunohistochemical staining revealed that FGF-2 was moderately expressed in the epithelial cells of duct-like structures (DLS) and newly formed acinar cells (NFAC) at days 0-7, and strongly in intercalated duct (ICD) at control gland and Day 7-14. FGF-7 was localized moderately in NFAC and DLS. FGF-8 was localized moderately in the epithelial cells of DLS during regeneration. Strong positive immunoreactions for FGF-10 were found in NFAC and the epithelial cells of DLS during regeneration, as well as the ICD and lateral surfaces of the maturing acinar cells (MAC). FGFR-1 was expressed moderately in the ICD, and weakly in the NFAC and MAC. Positive immunoreactions for FGFR-2 were not observed during regeneration. Additionally, FGFR-4 was detected strongly in the ICD and slightly in NFAC. These findings suggest that FGF-2, -7, -8 and -10 play important roles in NFAC, MAC, and DLS through FGFR-1 and -4 during regeneration of submandibular gland.
