Abstract
Background: Although several approaches have revealed much about individual factors that regulate pancreatic development, we have yet to fully understand their complicated interplay during pancreas morphogenesis. Gfi1 is transcription factor specifically expressed in pancreatic acinar cells, whose role in pancreas cells fate identity and specification is still elusive. Methods: In order to gain further insight into the function of this factor in the pancreas, we generated animals deficient for Gfi1 specifically in the pancreas. Gfi1 conditional knockout animals were phenotypically characterized by immunohistochemistry, RT-qPCR, and RNA scope. To assess the role of Gfi1 in the pathogenesis of diabetes, we challenged Gfi1-deficient mice with two models of induced hyperglycemia: long-term high-fat/high-sugar feeding and streptozotocin injections. Results: Interestingly, mutant mice did not show any obvious deleterious phenotype. However, in depth analyses demonstrated a significant decrease in pancreatic amylase expression, leading to a diminution in intestinal carbohydrates processing and thus glucose absorption. In fact, Gfi1-deficient mice were found resistant to diet-induced hyperglycemia, appearing normoglycemic even after long-term high-fat/high-sugar diet. Another feature observed in mutant acinar cells was the misexpression of ghrelin, a hormone previously suggested to exhibit anti-apoptotic effects on β-cells in vitro. Impressively, Gfi1 mutant mice were found to be resistant to the cytotoxic and diabetogenic effects of high-dose streptozotocin administrations, displaying a negligible loss of β-cells and an imperturbable normoglycemia. Conclusions: Together, these results demonstrate that Gfi1 could turn to be extremely valuable for the development of new therapies and could thus open new research avenues in the context of diabetes research.

Abstract
In the context of type 1 diabetes research and the development of insulin-producing β-cell replacement strategies, whether pancreatic ductal cells retain their developmental capability to adopt an endocrine cell identity remains debated, most likely due to the diversity of models employed to induce pancreatic regeneration. In this work, rather than injuring the pancreas, we developed a mouse model allowing the inducible misexpression of the proendocrine gene Neurog3 in ductal cells in vivo. These animals developed a progressive islet hypertrophy attributed to a proportional increase in all endocrine cell populations. Lineage tracing experiments indicated a continuous neo-generation of endocrine cells exhibiting a ductal ontogeny. Interestingly, the resulting supplementary β-like cells were found to be functional. Based on these findings, we suggest that ductal cells could represent a renewable source of new β-like cells and that strategies aiming at controlling the expression of Neurog3, or of its molecular targets/co-factors, may pave new avenues for the improved treatments of diabetes.

Abstract
Diabetes can result from the loss or dysfunction of insulin-producing δ cells. Druelle et al. find that ectopic expression of the pancreatic beta cell master gene Pax4 in somatostatin-expressing δ cells triggers an endocrine cell neogenesis process. Importantly, the beta-like cells thereby generated are functional and can partly reverse the consequences of chemically induced diabetes. The recent demonstration that pancreatic α cells can be continuously regenerated and converted into β-like cells upon ectopic expression of Pax4 opened new avenues of research in the endocrine cell differentiation and diabetes fields. To determine whether such plasticity was also shared by δ cells, we generated and characterized transgenic animals that express Pax4 specifically in somatostatin-expressing cells. We demonstrate that the ectopic expression of Pax4 in δ cells is sufficient to induce their conversion into functional β-like cells. Importantly, this conversion induces compensatory mechanisms involving the reactivation of endocrine developmental processes that result in dramatic β-like cell hyperplasia. Importantly, these β-like cells are functional and can partly reverse the consequences of chemically induced diabetes.

Abstract
Diabetes is a chronic and progressing disease, the number of patients increasing exponentially, especially in industrialized countries. Regenerating lost insulin-producing cells would represent a promising therapeutic alternative for most diabetic patients. To this end, using the mouse as a model, we reported that GABA, a food supplement, could induce insulin-producing beta-like cell neogenesis offering an attractive and innovative approach for diabetes therapeutics.

Abstract
To efficiently treat type 1 diabetes, exogenous insulin injections currently represent the main approach to counter chronic hyperglycaemia. Unfortunately, such a therapeutic approach does not allow for perfectly maintained glucose homeostasis and, in time, cardiovascular complications may arise. Therefore, seeking alternative/improved treatments has become a major health concern as an increasing proportion of type 2 diabetes patients also require insulin supplementation. Towards this goal, numerous laboratories have focused their research on β-cell replacement therapies. Herein, we will review the current state of this research area and describe the cell sources that could potentially be used to replenish the depleted β-cell mass in diabetic patients.

Abstract
Squamous cell carcinoma is a morphologically heterogenous neoplasm of specific histologic entities involved in human papillomavirus infection. The condylomatous types of squamous cell vulvar carcinoma, caused by HPV-16, most often manifest as exophytic papillary tumors mimicking condylomas.

Abstract
A diagnostic and therapeutic approach in the identification of malignant lesions and the types of HPV in 11 patients with gigantic condylomatous vulvar protuberances is presented. Different histological types of squamous cell vulvar carcinoma have been found in 8 (72.7%) cases: condylomatous (4), verrucous (3) and basaloid type of the carcinoma (1). HPV type 16, confirmed in 5 cases, was most often present (4 condylomatous and 1 basaloid carcinoma types). Other types of HPV such as HPV-6 was detected in 3 cases of verrucous, type 11 in 2 cases of verrucous and condylomatous carcinoma and type 18 in 1 case of condylomatous carcinoma. Radical vulvectomy followed by bilateral inguinofemoral lymphadenectomy was performed in 4 patients with condylomatous carcinoma, hemivulvectomy in basaloid carcinoma whereas wide local excision was performed in the verrucous type of carcinoma. No patient died except 1 with condylomatous carcinoma in whom 6 positive lymph nodes were detected after the primary operation. The patient died 4 years later following 3 excisions of local recurrences.
