Основным звеном внутриклеточных реакций, индуцированных АВП, является транслокация везикул, содержащих водные каналы (аквапорины-2), в плазматическую мембрану главных клеток эпителия собирательных трубок. В интерстиции внутреннего мозгового вещества почки сосредоточено значительное количество отрицательно заряженного глюкозаминогликана, гиалуронана, который может влиять на диффузию воды между структурами концентрирующего механизма в зависимости от состояния его полимерности. Вопрос о роли гиалуронана в регуляции транспорта воды в почке млекопитающих остается дискуссионным. С использованием ОТ-ПЦР реального времени проверялась гипотеза о вовлечении генов, кодирующих ключевые ферменты метаболизма гиалуронана, в долговременный эффект вазопрессина на концентрирующую функцию почек. Экспрессия генов гиалуронан-синтазы 2 (Has2), гиалуронидазы-1 и гиалуронидазы-2 (Hyal1 и Hyal2), исследована в почке гидратированных крыс линии WAG (Wistar Albino Glaxo) и у крыс, которым в течение двух дней внутрибрюшинно вводился селективный агонист V2- рецепторов вазопрессина dDAVP (200 мкг/кг веса тела, дважды в день внутрибрюшинно). Содержание мРНК Has2 было наиболее высоким в мозговом веществе, сосочке почки гидратированных крыс. dDAVP индуцировал значительное снижение содержания мРНК Has2 в этой зоне, в корковом веществе изменения были менее выражены. В противоположность Has2, введение dDAVP сопровождалось значительным повышением содержания мРНК Hyal1 и Hyal2 в сосочке почки, при этом наблюдались выраженное повышение активности гиалуронидазы в почечной ткани и нарастание осмолярности отделяющейся мочи. Предполагается, что вазопрессин ингибирует синтез гиалуронана и одновременно стимулирует его деградацию в интерстициальной ткани сосочка почки, повышая проницаемость матрикса и облегчая ток воды между элементами противоточной концентрирующей системы путем регуляции экспрессии генов ключевых ферментов метаболизма гиалуронана.</p></abstract><trans-abstract xml:lang="en"><p>In mammals, arginine-vasopressin (AVP) is a major hormone involved in the regulation of renal water reabsorption, acting via an increase in the osmotic permeability of the collecting duct epithelium. The AVP-induced intracellular events include, as an essential step, the trafficking of the vesicles containing the water channels, aquaporin-2, to the apical plasma membrane of the collecting duct principal cells. The interstitium of the renal inner medulla contains abundant linear negatively charged glycosaminoglycan hyaluronan (HA), which affects the water flow depending on their polymeric state. Using real-time RT-PCR, we tested the assumption that the renal hyaluronan may be involved in the longterm vasopressin effect on water reabsorption. The expression of the genes encoding hyaluronan synthase-2 (Has2) and hyaluronidase-1, 2 (Hyal1, Hyal2) in the kidneys of Wistar Albino Glaxo (WAG) was studied. Has2 mRNA content was the highest in the kidney papilla of the hydrated rats. The V2 receptor-selective vasopressin analog dDAVP (100 μg/kg bw, ip, twice a day for 2 days) induced a considerable decrease in Has2 mRNA content in the papilla with less pronounced changes in the cortex. In contrast to Has2, dDAVP treatment caused a significant increase in Hyal1 and Hyal2 mRNA content in the renal papilla. There was a good fit between Hyal1 and Hyal2 transcriptional level and changes in hyaluronidase activity in the renal tissue. It was suggested that vasopressin is able to inhibit the synthesis of hyaluronan and concomitantly promotes its degradation in the renal papilla interstitium, thereby facilitating water flow between elements of the renal countercurrent system. The implications for this effect are discussed in the context of the literature data.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вазопрессин</kwd><kwd>почка</kwd><kwd>гиалуронан</kwd><kwd>гиалуронан- синтаза-2</kwd><kwd>гиалуронидаза-1</kwd><kwd>2</kwd><kwd>экспрессия генов</kwd><kwd>осмотическое концентрирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vasopressin</kwd><kwd>kidney</kwd><kwd>hyaluronan</kwd><kwd>hyaluronansynthase-2</kwd><kwd>hyaluronidase-1</kwd><kwd>2</kwd><kwd>gene expression</kwd><kwd>water reabsorption</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">Закс М.Г., Титова М.М.
