Background: Mammalian puberty is initiated by the pulsatile release of gonadotropin-releasing hormone (GnRH) from hypothalamic neurons. Enhanced at puberty (Eap) 1 is a transcription factor within this regulatory network integrating exogenous and endogenous informations, e.g. weight. Recent studies indicate an epigenetic regulation of the pubertal process.Objective and hypotheses: This study investigates if overweight modifies epigenetic marks i...

Background: Gonadotropin releasing hormone (GnRH)-secretion is not only regulated by neuronal factors but also by astroglia cells via growth factors (transforming growth factor α (TGFα), neuregulin (NRG)), prostaglandin E2 (PGE2) and the erbB receptor family. Mutations of TGFα and erbB1 result in an impaired reproductive capacity. Mice show a characteristically skin phenotype with wavy hair and curly whiskers. The rat strain SPRD-Cu3 (curly) shows a sim...

Delayed puberty (DP) in boys is considered the most common hypoandrogenia of puberty. It should be noted that DP adversely affects physical development, body formation and the health status of adolescents. The heterogeneity of the population of adolescents with DP has led to a differentiated approach and the allocation of the following three clinical options (CO) of DP: 1 - DP, accompanied by growth retardation; 2 - DP without significant deviations in physical development; 3 ...

Background: Pseudohypoparathyroidism 1A, newly classified as inactivating PTH/PTHrP signaling disorder type 2 (iPPSD2), is defined by resistance to parathyroid hormone, short stature and early-onset obesity. Short stature is caused by skeletal dysplasia and additionally, in some cases, also by the coexistence of growth hormone deficiency, as other hormonal resistances might be present (e.g. thyroid-stimulating hormone, growth hormone releasing hormone (GHRH), ...

Background: The MC4R pathway is the principal regulator of mammalian energy balance through its modulation of energy intake and energy expenditure. Variants in genes associated with the MC4R pathway can result in rare genetic diseases of obesity. Clinical data in patients with genetic defects in the MC4R pathway indicate that setmelanotide, an MC4R agonist, can effectively reduce weight and hunger in scientifically rationalized obese subpopulations in which MC...

Objective: Determination of changes in metabolic status and vitamin D concentrations in obese children.Methods: We examined 210 children in the University Hospital (Minsk) from 2021 to 2022 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of vitamin D, OPG, insulin were determined. All children were divided into 2 groups: group 1 children with morbid obesity (MO) ...

Objective: determination of changes in metabolic status and vitamin D concentrations in obese children.Methods: We examined 221 children in the University Hospital (Minsk) from 2019 to 2021 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of vitamin D, insulin were determined. All children were divided into 2 groups: group 1 children with morbid obesity (MO) - 159...

Objective: determination of changes in metabolic status and osteoprotegerin (OPG) concentrations in obese children.Methods: We examined 220 children in the University Hospital (Minsk) from 2022 to 2023 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of OPG, insulin were determined. All children were divided into 2 groups: group 1 children with morbid obesity (MO)...

Background: The melanocortin-4 receptor (MC4R) pathway is critical for the regulation of energy balance. Variants in a number of genes within this pathway have well-established associations with severe obesity. However, the overall frequency of rare variants in these genes has not been assessed systematically in a clinically relevant population, and it is unknown whether variant frequency differs depending on the age of ascertainment. Genetic testing can impro...

Objective: determination of changes in metabolic status and osteoprotegerin concentrations in obese children.Methods: We examined 120 children in the University Hospital (Minsk) from 2017 to 2019 yrs. Their anthropometric parameters (height, weight, body mass index (BMI)) were determined. Blood levels of osteoprotegerin (OPG), insulin were determined. In the biochemical blood test, the parameters of uric acid, insulin we...
