Myotonic dystrophy type 1 (DM1) is a complex neuromuscular disease characterized by skeletal muscle wasting, weakness, and myotonia. DM1 caused the accumulation of CUG repeats, which alter biological activities RNA-binding proteins, including CUG-binding protein (CUGBP1). CUGBP1 an important translational regulator that activated cyclin D3-dependent kinase 4 (CDK4). Here we show mutant repeats suppress Cdk4 signaling increasing stability activity glycogen synthase 3β (GSK3β). Using mouse...

Background Survivors of childhood acute lymphoblastic leukaemia (ALL) treated with haematopoietic stem cell transplantation and total body irradiation (HSCT/TBI) have a high cardiometabolic risk despite lacking overt clinical obesity. This study characterised composition using different methodologies explored associations reduced insulin sensitivities in group ALL survivors with/without HSCT/TBI. Procedure HSCT/TBI (n = 20,10 M) were compared Chemotherapy‐only 31), an obese non‐leukaemic...

Significance Inherited multisystemic diseases, myotonic dystrophies type 1 (DM1) and 2 (DM2), are caused by long CUG CCUG RNA repeats. The mutant repeats should be degraded after intron excision; however, this accumulates in cells, leading to pathology. Although RNAs may with synthetic oligonucleotides, the identification of a cause increased stability would help improve efficiency their degradation. We found that reduction helicase p68 skeletal muscle biopsies DM1 DM2 patients contributes...

Myotonic dystrophy type 1 (DM1) is a progressive neuromuscular disease caused by expanded CUG repeats, which misregulate RNA metabolism through several RNA-binding proteins, including CUG-binding protein/CUGBP1 elav-like factor (CUGBP1/CELF1) and muscleblind protein. Mutant repeats elevate CUGBP1 alter activity via glycogen synthase kinase 3β (GSK3β)-cyclin D3-cyclin D-dependent 4 (CDK4) signaling pathway. Inhibition of GSK3β corrects abnormal in DM1 mice [human skeletal actin mRNA,...

Myotonic dystrophy type 2 (DM2) is a neuromuscular disease caused by an expansion of intronic CCTG repeats in the CNBP gene, which encodes protein regulating translation and transcription. To better understand role cellular nucleic acid binding (CNBP) DM2 pathology, we examined skeletal muscle new model Cnbp knockout (KO) mice. This study showed that loss disturbs myofibrillar sarcomeric organization at birth. Surviving homozygous KO mice develop atrophy young age. The phenotype heterozygous...

Myotonic dystrophy type 1 (DM1), an incurable, neuromuscular disease, is caused by the expansion of CTG repeats within 3' UTR DMPK on chromosome 19q. In DM1 patients, mutant transcripts deregulate RNA metabolism altering CUG RNA-binding proteins. Several approaches have been proposed for therapy focused specific degradation or correction proteins, affected repeats. One such protein (CUGBP1). The ability CUGBP1 to increase inhibit translation depends phosphorylation at Ser302, which mediated...

Background: Thyroid nodules are common and most benign. Previous data from our laboratory others has suggested that gene profiling can accurately distinguish between benign malignant thyroid provide new leads in the study of tumorigenesis. Current preoperative techniques do not permit distinction neoplastic hyperplastic follicular neoplasms. These studies were undertaken to determine whether tumors could be subcategorized by molecular profiling. Methods: Molecular profiles 8 adenomas...

Childhood cancer survivors treated with haematopoietic stem cell transplantation (HSCT) and total body irradiation are at an increased risk of developing diabetes early in life due to insulin resistance β-cell dysfunction, but the optimal screening method is unknown. The National Institute for Health Care Excellence guidelines community recommend using fasting glucose ≥ 7 mmol/l and/or HbA1c 48 mmol/mol (6.5%) diagnosis and, 5.5-6.9 or 42-47 (6-6.5%) indicate high risk. This study aimed...

ABCC8 gene mutations with different inheritance patterns have been well described to cause transient and permanent forms of neonatal diabetes onset hyperglycemia commonly before the age 6 months, rare cases between 12 months. However, recent analyses also demonstrated in patients monogenic (maturity young, MODY), milder clinical phenotypes later hyperglycemia. We report two siblings mellitus due a novel homozygous p.(Phe1068Ile) (c.3202T>A) missense mutation gene, but significantly...

Two Caucasian girls, both of normal weight and body mass indices, were diagnosed with type A insulin resistance (IR) in childhood. Case 1 presented premature adrenarche aged 7 years, then by age 12 years had hirsutism, acne, acanthosis nigricans, asymptomatic diabetes. Subsequent investigation revealed raised adiponectin (15.3 mg/L) heterozygous p.Pro1205Leu mutation the INSR gene encoding receptor. She experienced postprandial hypoglycaemia on metformin; acarbose was trialled discontinued...

Accurate histological diagnosis and classification of germ cell tumours (GCTs) is key to informing successful therapeutic surveillance strategy. The modern approach for yolk sac tumour (YST) highly curative. Because YST takes on a large morphological spectrum, it can be confused other GCT subtypes as well somatic carcinomas, particularly when presents in an extragonadal or metastatic setting. Currently available immunohistochemical markers are limited by suboptimal sensitivity specificity....
