Protective Effects of Combined Intervention with Adenovirus Vector Mediated IL-10 and IGF1 Genes on Endogenous Islet β Cells in Nonobese Diabetes Mice with Onset of Type 1 Diabetes Mellitus

Li Tang

Introduction: To investigate the protective effects of combined intervention with adenovirus vector mediated interleukin 10 (IL-10) and insulin-like growth factor 1 (IGF1) genes on islet β cells in nonobese diabetes (NOD) mice with type 1 diabetes mellitus (T1D) at early stage.Methods: Twenty-four female NOD mice at onset of diabetes and aged 17–20 weeks old were randomly divided into four groups. Mouse 1, 2 and 3 groups were intraperitoneally ...

Insight of Differential Diagnosis of DAX-1 from Two Patients with Elevated Testosterone in Early Infancy

Li Tang , Ge Juan

DAX-1 is Dosage-sensitive sex reversal - Adrenal hypoplasia congenita critical region on the X chromosome 1, caused by mutation of NR0B1. It commonly presents X-Linked adrenal hypoplasia congenital, hypogonadotropic hypogonadism and infertility. However, we observed two patients whose testosterone elevated in their early infancy. Both of them are males with uneventful gestation and birth, and have a primary symptom as jaundice. For patient 1, poor feeding and pigment genital a...

The Protective Effects of Adenovirus-mediated IL-10 Gene and Anti-CD20 Monoclonal Antibody on the Pancreatic β Cells of NOD Mice in the Early Stage of Natural T1D Onset

Li Tang , Li Cheng , Fan Lei , Tian Fei , Tang Aiping

Background: Type 1 diabetes (T1D) is an autoimmune disease (AID) whose primary features include progressive pancreatic β cell damage and absolute insufficient endogenous insulin secretion. Recent studies have shown that a Th1/Th2 cell subset unbalance and excessively activated B lymphocytes are important pathogenic mechanisms.Objective and hypotheses: To investigate the protective effects of Adenovirus-mediated IL-10 gene and anti-CD20 monoclonal an...

The Role of IGF1R Gene Mutation in the Development of Oligodendrocytes

Yang Fan , Tang Mei , Li Hedong

Background: IGF1R gene mutation usually cause IUGR. The children born with IUGR were prone to some kinds of brain function disorders.Objective and hypotheses: The dysfunction of the brain was caused by the abnormal oligodendrocyte development.To establish lentivirus vector of IGF1R gene mutation (R709Q) and transfect oligodendrocyte precursors (Ge6). Observe the IRS/MAPK and PI3K/Akt/PKB signaling pathway and the change of proliferation, differentiation,...

Infant with 45, XO DSD presented with Li Fraumeni syndrome, a case report from Kuwait.

Alfadhli Maryam , Alhenaidi Razan , Elshafie Reem , Alkandari Hessa , Alhomaidah Doha

Background: X-chromosome monosomy is the most common sex abnormality in females, with a higher prevalence of cancer than the general population. Virilizing adrenocortical tumors are rarely seen in patients with Turner’s Syndrome. There have been 2 reported cases of simultaneous TP53 mutations (Li Fraumeni’s syndrome) and Turner’s syndrome. Here we report first case with this rare association from Kuwait.Clinical...

Quantitative analysis of endogenous and exogenous steroid hormones is an important step for our understanding of the causes of endocrine disorders in pediatric. In this study, we developed a method to simultaneously quantify endogenous and exogenous steroids in pediatric urine and plasma. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to simultaneously quantify steroid hormones in children plasma and urine. Under the optimum conditions, th...

A Novel Deadly Variant in the TP53 Gene Causing Li-Fraumeni Syndrome. The Importance of Clinical Awareness and the Contribution of Molecular Diagnosis in Active Prevention Within Families with Multiple Tumor Incidents at a Young Age

Bothou Christina , Spyridis Georgios P , Papantonatos Dionysios A , Stratakis Constantine A , Papadimitriou Dimitrios T

Background: Li-Fraumeni Syndrome (LFS) is an autosomal dominant hereditary cancer syndrome associated with germline pathogenic variants in in the TP53 gene and high risk of a broad range of early-onset malignancies. The 70-77% of LFS associated tumors are: breast cancer, soft-tissue sarcoma, brain tumor, osteosarcoma and adrenocortical carcinoma. However, ovarian, pancreatic and gastrointestinal track tumors are also LFS-related. The patients with LFS are at risk for a second ...
