Мутации в гене, кодирующем МК4Р, – наиболее распространенная причина монолокусного ожирения у людей. Фактор роста фибробластов 21 (FGF21) рассматривают в качестве перспективного кандидата для медикаментозного лечения ожирения, однако неизвестно, влияет ли он на меланокортиновое ожирение. Пол особей необходимо учитывать при проведении доклинических исследований, но у лабораторных животных фармакологические эффекты FGF21 изучали только на самцах. В настоящей работе исследовано влияние FGF21 на метаболизм у самцов и самок мышей с мутацией lethal yellow в локусе агути (Ay ), которая приводит к блокаде МК4Р в гипоталамусе и развитию ожирения. Самцам и самкам мышей Ay линии C57Bl с развитым ожирением вводили подкожно в течение 10 дней физиологический раствор или FGF21 (1 мг/кг). Измеряли потребление пищи (ПП), массу тела (МТ), показатели крови и экспрессию генов в печени, мышцах, бурой жировой ткани, подкожной и висцеральной белой жировой ткани и гипоталамусе. Эффекты FGF21 зависели от пола животных. У самцов FGF21 снижал МТ и уровень инсулина в крови и не влиял на ПП. У самок FGF21 увеличивал ПП и массу печени, но не влиял на МТ. У контрольных самок Ay экспрессия генов углеводно-жирового обмена (Ppargc1a, Cpt1, Pck1, G6p, Slc2a2) в печени и генов липогенеза (Pparg, Lpl, Slc2a4) в висцеральной жировой ткани была выше, чем у самцов, и введение FGF21 снижало экспрессию этих генов только у самок. Введение FGF21 уменьшало уровень мРНК ПОМК в гипоталамусе только у самцов. Полученные результаты демонстрируют, что фармакологический эффект FGF21 значительно различается у самцов и самок мышей с мутацией Ay : в отличие от самцов, самки проявляют устойчивость к катаболическому действию FGF21.</p></abstract><trans-abstract xml:lang="en"><p>Hypothalamic melanocortin 4 receptors (MC4R) regulate energy balance. Mutations in the MC4R gene are the most common cause of monogenic obesity in humans. Fibroblast growth factor 21 (FGF21) is a promising antiobesity agent, but its effects on melanocortin obesity are unknown. Sex is an important biological variable that must be considered when conducting preclinical studies; however, in laboratory animal models, the pharmacological effects of FGF21 are well documented only for male mice. We aimed at investigating whether FGF21 affects metabolism in male and female mice with the lethal yellow (Ay ) mutation, which results in MC4R blockage and obesity development. Obese C57Bl-Ay male and female mice were administered subcutaneously for 10 days with vehicle or FGF21 (1 mg per 1 kg). Food intake (FI), body weight (BW), blood parameters, and gene expression in the liver, muscles, brown adipose tissue, subcutaneous and visceral white adipose tissues, and hypothalamus were measured. FGF21 action strongly depended on the sex of the animals. In the males, FGF21 decreased BW and insulin blood levels without affecting FI. In the females, FGF21 increased FI and liver weight, but did not affect BW. In control Ay -mice, expression of genes involved in lipid and glucose metabolism (Ppargc1a, Cpt1, Pck1, G6p, Slc2a2) in the liver and genes involved in lipogenesis (Pparg, Lpl, Slc2a4) in visceral adipose tissue was higher in females than in males, and FGF21 administration inhibited the expression of these genes in females. FGF21 administration decreased hypothalamic POMC mRNA only in males. Thus, the pharmacological effect of FGF21 were significantly different in male and female Ay -mice; unlike males, females were resistant to catabolic effects of FGF21.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>FGF21</kwd><kwd>мыши Ay</kwd><kwd>меланокортиновое ожирение</kwd><kwd>половые различия</kwd><kwd>печень</kwd><kwd>гипоталамус.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>FGF21</kwd><kwd>Ay -mice</kwd><kwd>melanocortin obesity</kwd><kwd>sex differences</kwd><kwd>liver</kwd><kwd>hypothalamus</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bazhan N., Jakovleva T., Balyibina N., Dubinina A., Denisova E., Feofanova N., Makarova E.
