Overexpression of INSM1, NOTCH1, NEUROD1, and YAP1 genes is associated with adverse clinical outcome in pediatric neuroblastoma. Virchows Arch 2022; 481:925-933. [PMID: 36121500 PMCID: PMC9734219 DOI: 10.1007/s00428-022-03406-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Revised: 08/12/2022] [Accepted: 08/27/2022] [Indexed: 01/22/2023]
Abstract
Pediatric neuroblastoma is responsible for approximately 8-10% of pediatric tumors, and it is one of the leading causes of tumor-related deaths in children. Although significant progress has been made in the characterization of neuroblastoma in recent years, the mechanisms influencing the prognosis of neuroblastoma patients remain largely unknown. Our aim was to investigate if the major neuroendocrine-associated transcriptional drivers, including ASCL1, NEUROD1, DLL3, NOTCH1, INSM1, MYCL1, POU2F3 and YAP1 are correlated with specific clinical and pathological characteristics. We selected a retrospective series of 46 primary pediatric neuroblastoma, composed of 30 treatment-naïve and 16 post-chemotherapy cases. Gene expression levels were explored by means of quantitative real-time PCR. An increased expression of NOTCH1 (p = 0.005), NEUROD1 (p = 0.0059), and YAP1 (p = 0.0008) was found in stage IV tumors, while the highest levels of MYCL1 and ASCL1 were seen in stages IVS and III, respectively (p = 0.0182 and p = 0.0134). A higher level of NOTCH1 (p = 0.0079) and YAP1 (p = 0.0026) was found in cases with differentiating morphology, while high mitosis-karyorrhexis index cases demonstrated significantly lower levels of POU2F3 (p = 0.0277). High expression of NOTCH1 (p = 0.008), NEUROD1 (p = 0.026), INSM1 (p = 0.010), and YAP1 (p = 0.005) together with stage IV (p = 0.043) was associated with shorter disease-free survival. In summary, our data indicate that the assessment of gene expression levels of neuroendocrine-lineage transcription factors might help to identify neuroblastoma patients with the risk of relapse.

Abstract
BACKGROUND & AIMS Maternal liver shows robust adaptations to pregnancy to accommodate the metabolic needs of the developing and growing placenta and fetus by largely unknown mechanisms. We found that Ascl1, a gene encoding a basic helix-loop-helix transcription factor essential for neuronal development, is highly activated in maternal hepatocytes during the second half of gestation in mice. METHODS To investigate whether and how Ascl1 plays a pregnancy-dependent role, we deleted the Ascl1 gene specifically in maternal hepatocytes from midgestation until term. RESULTS As a result, we identified multiple Ascl1-dependent phenotypes. Maternal livers lacking Ascl1 showed aberrant hepatocyte structure, increased hepatocyte proliferation, enlarged hepatocyte size, reduced albumin production, and increased release of liver enzymes, indicating maternal liver dysfunction. Simultaneously, maternal pancreas and spleen and the placenta showed marked overgrowth; and the maternal ceca microbiome showed alterations in relative abundance of several bacterial subpopulations. Moreover, litters born from maternal hepatic Ascl1-deficient dams experienced abnormal postnatal growth after weaning, implying an adverse pregnancy outcome. Mechanistically, we found that maternal hepatocytes deficient for Ascl1 showed robust activation of insulin-like growth factor 2 expression, which may contribute to the Ascl1-dependent phenotypes widespread in maternal and uteroplacental compartments. CONCLUSIONS In summary, we show that maternal liver, via activating Ascl1 expression, modulates the adaptations of maternal organs and the growth of the placenta to maintain a healthy pregnancy. Our studies show that Ascl1 is a novel and critical regulator of the physiology of pregnancy.

ASCL1 is a MYCN- and LMO1-dependent member of the adrenergic neuroblastoma core regulatory circuitry. Nat Commun 2019; 10:5622. [PMID: 31819055 PMCID: PMC6901540 DOI: 10.1038/s41467-019-13515-5] [Citation(s) in RCA: 45] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2019] [Accepted: 11/11/2019] [Indexed: 12/16/2022] Open
Abstract
A heritable polymorphism within regulatory sequences of the LMO1 gene is associated with its elevated expression and increased susceptibility to develop neuroblastoma, but the oncogenic pathways downstream of the LMO1 transcriptional co-regulatory protein are unknown. Our ChIP-seq and RNA-seq analyses reveal that a key gene directly regulated by LMO1 and MYCN is ASCL1, which encodes a basic helix-loop-helix transcription factor. Regulatory elements controlling ASCL1 expression are bound by LMO1, MYCN and the transcription factors GATA3, HAND2, PHOX2B, TBX2 and ISL1-all members of the adrenergic (ADRN) neuroblastoma core regulatory circuitry (CRC). ASCL1 is required for neuroblastoma cell growth and arrest of differentiation. ASCL1 and LMO1 directly regulate the expression of CRC genes, indicating that ASCL1 is a member and LMO1 is a coregulator of the ADRN neuroblastoma CRC.

Abstract
The insulin-like growth factor (IGF) signaling system plays key roles in the establishment and progression of different types of cancer. In agreement with this idea, substantial evidence has shown that the type I IGF receptor (IGF-IR) and its primary ligand IGF-I are important for maintaining the survival of malignant cells of hematopoietic origin. In this review, we discuss current understanding of the role of IGF-IR signaling in cancer with a focus on the hematological neoplasms. We also address the emergence of IGF-IR as a potential therapeutic target for the treatment of different types of cancer including plasma cell myeloma, leukemia, and lymphoma.

Abstract
Upregulation of IGF2 occurs in both childhood and adult malignancies. Its overexpression is associated with resistance to chemotherapy and worse prognosis. IGF2 promoter usage is developmentally regulated; however, malignant tissues are characterized by re-activation of the fetal IGF2 promoters, especially P3. In this review, we describe the mechanisms of IGF2 signaling and regulation in normal and malignant tissues and their clinical implications.

Abstract
Cancer/testis antigens (CTA) are a heterogeneous group of antigens that are expressed preferentially in tumor cells and testis. Based on this definition the human membrane-associated phospholipase A1 beta (lipase family member I, LIPI) has been identified as CTA. The high homology of LIPI and the membrane-associated phospholipase A1 alpha (lipase family member H, LIPH) suggests that both genes are derived from a common ancestor by gene duplication. In contrast to human LIPI, human LIPH is expressed in several tissues. LIPI sequences have only been identified in mammals. Here, we describe the identification of LIPI in non-mammalian vertebrates. Based on the conserved genomic organization of LIPI and LIPH we identified sequences for both lipases in birds and fishes. In all vertebrates the LIPI locus is neighbored by a member of the RNA binding motif (RBM) family, RBM11. By sequencing of reverse transcriptase-polymerase chain reaction products we determined the sequences of LIPI and LIPH messenger RNA from broilers. We found that the sequence homology between LIPI and LIPH is much higher in non-mammalian species than in mammals. In addition, we found broad expression of LIPI in broilers, resembling the expression profile of LIPH. Our data suggest that LIPI is a CTA only in mammalian species and that the unique sequence features of the mammalian LIPI/RBM11 locus have evolved together with the CTA-like expression pattern of LIPI.
