Abstract
Loss-of-function mutations of the multiple endocrine neoplasia type 1 (MEN1) gene are causal to the MEN1 endocrine tumor syndrome, but they are also commonly found in sporadic pancreatic neuroendocrine tumors and other types of cancers. The MEN1 gene product, menin, is involved in transcriptional and chromatin regulation, most prominently as an integral component of KMT2A/MLL1 and KMT2B/MLL2 containing COMPASS-like histone H3K4 methyltransferase complexes. In a mutually exclusive fashion, menin also interacts with the JunD subunit of the AP-1 and ATF/CREB transcription factors. After in silico screening of 253 disease-related MEN1 missense mutations, we selected a set of nine menin mutations in surface-exposed residues. The protein interactomes of these mutants were assessed by quantitative mass spectrometry, which indicated that seven of the nine mutants disrupt interactions with both MLL1/2 and JunD complexes. Interestingly, we identified three missense mutations, R52G, E255K and E359K, which predominantly reduce the interaction with MLL1 compared to JunD. This observation was supported by a pronounced loss of binding of the R52G, E255K and E359K mutant proteins at unique MLL1 genomic binding sites with less effect on unique JunD sites. These findings support the general importance of the menin-MLL1 and menin-JunD interactions in MEN1 gene-associated pathogenic conditions. Presentation: No date and time listed

Abstract
Context: Hormone treatment (HT) is a cornerstone of gender-affirming therapy in transgender and gender non-conforming people. Non-binary and genderqueer (NBGQ) people, individuals identifying in between or outside the male to female binary, are increasingly recognized. Not all trans people and NBGQ binary individuals seek full HT. Current guidelines for HT of transgender and gender non-conforming people do not include specific regimens for people who seek partial treatment. Objective: To compare HT prescribed to NBGQ and binary trans people. Design: Retrospective study. Setting: Referral clinic for gender dysphoria. Participants: 602 applicants for gender care in 2013-2015. Intervention: GenderQueer Identity questionnaires at entry were used to categorize people as NBGQ or binary transgender. Medical records were assessed until the end of 2019. Main Outcome Measures: prescribed HT, serum estradiol and testosterone concentrations. Results: 113 individuals identified as non-binary and 489 as binary transgender. NBGQ persons were more likely to receive partial HT than binary transgender people (11% versus 4.7%, p=0.02). None of the NBGQ individuals who received partial HT had undergone gonadectomy, hypogonadism did not occur. NBGQ individuals assigned male at birth using only estradiol had similar estradiol and higher testosterone serum concentrations compared with individuals using conventional HT. Conclusions: NBGQ individuals are more likely to receive partial HT compared with binary transgender people. In the future, tailored endocrine counseling may further shape partial HT regimens for NBGQ individuals.

Abstract
OBJECTIVE Epigenetic changes contribute to pancreatic neuroendocrine tumor (PanNET) development. Hypermethylation of promoter DNA as a cause of tumor suppressor gene silencing is a well-established oncogenic mechanism that is potentially reversible and therefore an interesting therapeutic target. Multiple endocrine neoplasia type 1 (MEN1) is the most frequent cause of inherited PanNETs. The aim of this study was to determine promoter methylation profiles in MEN1-related PanNETs. DESIGN AND METHODS Methylation-specific multiplex ligation-dependent probe amplification was used to assess promoter methylation of 56 tumor suppressor genes in MEN1-related (n = 61) and sporadic (n = 34) PanNETs. Differences in cumulative methylation index (CMI), individual methylation percentages and frequency of promoter hypermethylation between subgroups were analyzed. RESULTS We found promoter methylation of a large number of potential tumor suppressor genes. CMI (median CMI: 912 vs 876, P = 0.207) was the same in MEN1-related and sporadic PanNETs. We found higher methylation percentages of CASP8 in MEN1-related PanNETs (median: 59% vs 16.5%, P = 0.002). In MEN1-related non-functioning PanNETs, the CMI was higher in larger PanNETs (>2 cm) (median: 969.5 vs 838.5; P = 0.021) and in PanNETs with liver metastases (median: 1036 vs 869; P = 0.013). Hypermethylation of MGMT2 was more frequent in non-functioning PanNETs compared to insulinomas (median: 44.7% vs 8.3%; P = 0.022). Hypermethylation of the Von Hippel-Lindau gene promoter was observed in one MEN1-related PanNET and was associated with loss of protein expression. CONCLUSION Promoter hypermethylation is a frequent event in MEN1-related and sporadic PanNETs. Targeting DNA methylation could be of therapeutic value in MEN1 patients with advanced PanNETs.

Abstract
PURPOSE Pancreatic neuroendocrine tumors are a major manifestation of multiple endocrine neoplasia type 1 (MEN1). This tumor syndrome is caused by germline mutations in MEN1, encoding menin. Insight into pathogenesis of these tumors might lead to new biomarkers and therapeutic targets for these patients. Several lines of evidence point towards a role for p27Kip1 and p18Ink4c in MEN1-related tumor development in animal models for MEN1, but their contribution to human MEN1-related pancreatic neuroendocrine tumor development is not known. METHODS In this study, we characterized protein expression of p27Kip1 and p18Ink4c in human MEN1-related PanNETs by immunohistochemistry. From the nationwide DutchMEN1 Study Group database including > 90% of the Dutch MEN1 population, MEN1-patients, who underwent pancreatic surgery, were selected. A tissue micro-array was constructed with available paraffin tissue blocks, and PanNETs from 61 MEN1 patients were eligible for analysis. RESULTS Expression of p27Kip1 was high in 57 (93%) PanNETs and 67% of the tumors showed low expression of p18Ink4c (67.3%). No association was found between expression of either p27Kip1 or p18Ink4c and clinic-pathological characteristics. CONCLUSIONS These findings indicate that loss of p18Ink4c, but not p27Kip1, is a common event in the development of MEN1-related PanNETs. Restoration of p18Ink4c function through CDK4/6 inhibitors could be a therapeutic option for MEN1-related PanNETs.

Abstract
Mutations of the multiple endocrine neoplasia type 1 (MEN1) gene lead to loss of function of its protein product menin. In keeping with its tumor suppressor function in endocrine tissues, the majority of the MEN1-related neuroendocrine tumors (NETs) show loss of heterozygosity (LOH) on chromosome 11q13. In sporadic NETs, MEN1 mutations and LOH are also reported, indicating common pathways in tumor development. Prevalence of thymic NETs (thNETs) and pulmonary carcinoids in MEN1 patients is 2-8%. Pulmonary carcinoids may be underreported and research on natural history is limited, but disease-related mortality is low. thNETs have a high mortality rate. Duodenopancreatic NETs (dpNETs) are multiple, almost universally found at pathology, and associated with precursor lesions. Gastrinomas are usually located in the duodenal submucosa while other dpNETs are predominantly pancreatic. dpNETs are an important determinant of MEN1-related survival, with an estimated 10-year survival of 75%. Survival differs between subtypes and apart from tumor size there are no known prognostic factors. Natural history of nonfunctioning pancreatic NETs needs to be redefined because of increased detection of small tumors. MEN1-related gastrinomas seem to behave similar to their sporadic counterparts, while insulinomas seem to be more aggressive. Investigations into the molecular functions of menin have led to new insights into MEN1-related tumorigenesis. Menin is involved in gene transcription, both as an activator and repressor. It is part of chromatin-modifying protein complexes, indicating involvement of epigenetic pathways in MEN1-related NET development. Future basic and translational research aimed at NETs in large unbiased cohorts will clarify the role of menin in NET tumorigenesis and might lead to new therapeutic options.

Abstract
OBJECTIVE Multiple endocrine neoplasia type 1 (MEN1) is a hereditary syndrome characterized by parathyroid, gastroenteropancreatic, pituitary and adrenal tumours. Cardiovascular disease has been identified as an important cause of death in MEN1 patients. Menin, the product of the MEN1 gene, is a co-activator for peroxisome proliferator-activated receptor-γ and the vitamin D receptor, which are involved in glucose metabolism. We aimed to compare insulin sensitivity and prevalence of impaired fasting glucose and diabetes mellitus between MEN1 patients and controls. DESIGN Cross-sectional study. PATIENTS Sixty-three MEN1 gene mutation carriers (44% men, mean age 41 years) from 22 kindreds and 126 unrelated controls matched for gender, age and BMI. MEASUREMENTS Fasting glucose levels were categorized and compared using WHO criteria. Homeostasis model assessment (HOMA) was used as a measure of insulin resistance. RESULTS Homeostasis model assessment was significantly increased in MEN1 patients compared with controls (3·0 ± 2·0 vs 2·0 ± 1·0, P < 0·05). In MEN1 patients, HOMA was associated with BMI, but not with age, calcium and gastrin levels. Using logistic regression analysis, the presence of hyperparathyroidism, pancreatic lesions and various other manifestations was not associated with HOMA. Impaired fasting glucose was more prevalent in MEN1 compared with controls (17%vs 6%, P < 0·05). Three MEN1 patients (5%) compared with four controls (3%) were diabetic (not significant). CONCLUSIONS Multiple endocrine neoplasia type 1 patients had decreased insulin sensitivity and higher prevalence of impaired fasting glucose compared with controls, which was unrelated to MEN1 manifestations. Impaired glucose metabolism may result in increased risk of cardiovascular disease in MEN1 patients.

Abstract
Multiple endocrine neoplasia type 1 (MEN1) is caused by inactivating germ line mutations of the MEN1 tumour suppressor gene. The MEN1 gene product, menin, participates in many cellular processes, including regulation of gene transcription. As part of a protein complex that writes a trimethyl mark on lysine 4 of histone H3 (H3K4me3), menin is involved in activating gene transcription. Several functions of the menin histone methyltransferase complex have been discovered through protein interaction studies. Menin can interact with nuclear receptors and regulate transcription of hormone responsive target genes. Menin regulates transcription of cyclin-dependent kinase inhibitor and Hox genes via the chromatin-associated factor LEDGF. Aberrant expression of menin target genes in tumours in MEN1 patients suggests that loss of writing of the H3K4me3 mark contributes to MEN1 tumourigenesis. At present, drugs are being developed that target chromatin modifications. The identification of compounds that could restore H3K4me3 on menin target genes would provide new therapeutic strategies for MEN1 patients.
