27072116 Small cell lung cancer tissues were strongly positive for INSM1. INSM1 signal was not detected on normal adjacent tissues from lung cancer patients or normal lung tissues
26530405 the INSM1-promoter specific conditional replicating adenovirus represents a sensitive diagnostic tool to aid clinicians in the detection of NE tumors.
26482608 Insulinoma-Associated Protein 1 is a crucial regulator of neuroendocrine differentiation in lung cancer.
26386079 INSM1 expression was significantly increased in Neuroendocrine neoplastic vs nonneoplastic tissue.
25523979 INSM1 autoantibodies were associated with risk of developing type 1 diabetes.
23383108 A synthetic peptide corresponding to the immunosuppressive domain (amino acids 574-592) of HIV-1 gp41 upregulates the expression of insulinoma-associated 1 (INSM1) in peptide-treated PBMCs
21830214 Both the AR42J cell line and the primary cultured mouse acinar cells support role for INSM1 in pancreatic acinar cell trans-differentiation model.
21609490 The results suggest that INSM1 up-regulation plays a positive role in HSV-1 replication, probably by binding to the ICP0 promoter.
20215568 Data show that the consistent functional effect of INSM1, either with or without other ITFs, promotes pancreatic duct cell differentiation as well as induces Panc-1 cell cycle arrest.
19604042 The INSM1 promoter can direct herpes simplex virus thymidine kinase gene expression in a nude mouse model of neuroendocrine cancer and effectively repress tumor growth in response to ganciclovir treatment.
19246490 INSM1 role as an important regulator during neuroendocrine differentiation [review]
18417529 INSM1 is a new zinc-finger transcription factor that modulates insulin gene transcription during early pancreas development.
18205207 in mice and humans, INSM1 is likewise expressed transiently during terminal neurogenic divisions, from late progenitors to nascent neurons, and particularly during symmetric neuronogenic divisions.
18051367 A synthetic peptide corresponding to the immunosuppressive domain (amino acids 574-592) of HIV-1 gp41 upregulates the expression of insulinoma-associated 1 (INSM1) in peptide-treated PBMCs
16569215 results presented in this study define INSM1 as a transcriptional repressor of the neuroD/b2 gene. The molecular mechanism of INSM1 transcriptional repression is attributed to the recruitment of cyclin D1 and HDAC-1 and -3
12890672 IA-1 gene is developmentally expressed in the nervous system and the NeuroD1/E47 transcription factors up-regulate IA-1 gene expression through the proximal E-box element of the IA-1 promoter
11854618 IA-1 gene was shown to be developmentally regulated in fetal pancreatic cells, and its expression pattern is consistent with parallel changes in islet-specific transcription factors during the endocrine differentiation of AR42J cells.
