Regolazione dell’adrenalina e del glucosio della sintesi e della secrezione di leptina in un pesce teleosteo, la tilapia (Oreochromis mossambicus)

Lo stress acuto è regolato dall’asse simpatico adrenergico in cui le catecolamine mobilitano i negozi di energia insieme ai carboidrati come fattore principale della risposta allo stress endocrino. La leptina è una citochina vitale per la regolazione del dispendio energetico nei vertebrati ed è stimolata da numerosi fattori di stress nei pesci equivalenti al digiuno, al problema dell’iperosmosi e all’ipossia.

Tuttavia, si pensa poco alle interazioni regolatorie tra leptina e l’asse dello stress endocrino nei pesci e nei diversi vertebrati ectotermi. Abbiamo valutato le azioni dell’adrenalina e del glucosio nella regolazione della leptina A (LepA) in vivo e in vitro nella tilapia. Utilizzando le incubazioni degli epatociti e un omologo LepA ELISA , presentiamo che la sintesi e la secrezione di LepA diminuiscono con l’aumentare degli intervalli di glucosio ambientale (10-25 mM).

Al contrario, la somministrazione di glucosio in bolo nella tilapia aumenterà gli intervalli di mRNA di lepa di 14 volte a 6 ore, suggerendo che elementi sistemici regolati dal glucosio potrebbero contrastare i risultati inibitori diretti del glucosio sull’mRNA di lepa epatico osservati in vitro. L’adrenalina ha stimolato la secrezione di glucosio e LepA dagli epatociti con un andamento dose-dipendente entro 15 minuti, tuttavia ha avuto un impatto limitato sui range di mRNA di lepa. Un’iniezione in vivo di epinefrina nella tilapia ha stimolato un rapido aumento della glicemia che è stato adottato da un aumento di 4 volte negli intervalli di mRNA di lepa epatico a 2,5 e 6 ore. La LepA plasmatica è stata inoltre aumentata di 6 ore rispetto ai controlli. Tilapia ricombinante La somministrazione di LepA in vivo non ha avuto alcun impatto importante sui range di epinefrina plasmatica.

I risultati di questa ricerca mostrano che la LepA è regolata negativamente dall’aumento del glucosio extracellulare sullo stadio dell’epatocita, tuttavia stimolato dall’iperglicemia in vivo. Inoltre, l’adrenalina aumenterà la LepA. Questo, insieme al lavoro precedente che dimostra un impatto iperglicemico e glicogenolitico della LepA nella tilapia, significa che l’adrenalina potrebbe stimolare la secrezione di leptina per migliorare e ottimizzare la mobilizzazione del glucosio e l’omeostasi come parte della risposta allo stress incorporata e adattativa.

La leptina modula l’espressione genica all’interno del cuore coronarico e dei cardiomiociti nella direzione di mitigare il danno indotto dall’ischemia

La leptina , un ormone della sazietà derivato dagli adipociti, è stata precedentemente collegata alla cardioprotezione. Ora abbiamo dimostrato prima che la leptina conferisse resistenza al danno ischemico all’interno del cuore coronarico in topi transgenici αMUPA a lunga vita che sovraesprimono la leptina rispetto ai topi con gestione FVB/N di tipo selvatico (WT).

Per percepire il contributo della leptina al cuore coronarico ischemico, abbiamo misurato proprio qui l’espressione dei geni che codificano per la leptina e le proteine correlate all’ischemia nei topi αMUPA e WT all’interno del cuore coronarico rispetto al tessuto adiposo dopo infarto miocardico. Inoltre, esaminiamo l’espressione genica nei cardiomiociti neonatali di ratto al di sotto dell’ipossia in assenza e presenza di leptina aggiunta esogenamente o di un antagonista della leptina . Abbiamo usato RT-PCR in tempo reale e saggi ELISA o Western blot per misurare, rispettivamente, i range di mRNA e proteine.

I risultati hanno dimostrato che gli intervalli di leptina circolanti e gli intervalli di mRNA di leptina ed eme ossigenasi-1 (HO-1) all’interno del cuore coronarico sono stati elevati in ciascun genotipo di topo dopo 24 ore di infarto miocardico (MI), raggiungendo valori maggiori nei topi αMUPA. Al contrario, l’espressione genica della leptina nel tessuto adiposo era notevolmente elevata solo nei topi WT, raggiungendo tuttavia livelli di riduzione rispetto all’intestino. L’espressione dei geni proinfiammatori che codificano per TNFα, IL-1β è stata inoltre ampiamente elevata dopo MI all’interno del cuore coronarico in ciascuna varietà di topi, raggiungendo comunque intervalli significativamente ridotti nei topi αMUPA che indicano uno stato infiammatorio mitigato.

Nei cardiomiociti, gli intervalli di mRNA di tutti i geni sopra menzionati oltre ai geni HIF-1α e SOD2 sono stati elevati dopo l’ipossia. Il pretrattamento con leptina esogena ha ampiamente abbassato gli intervalli di mRNA di TNFα e IL-1β dopo l’ipossia, migliorando l’espressione di tutti i diversi geni e diminuendo gli intervalli di ROS. Il pretrattamento delle cellule con un antagonista della leptina ha aumentato esclusivamente i gradi di mRNA della leptina , suggerendo una regolazione sfavorevole dell’ormone sull’espressione del suo gene personale.

In totale, i risultati hanno dimostrato che la leptina influisce sull’espressione dei geni nei cardiomiociti al di sotto dell’ipossia in un modo che potrebbe mitigare l’irritazione e lo stress ossidativo, suggerendo lo stesso effetto della leptina endogena nei topi αMUPA. Inoltre, la leptina ha maggiori probabilità di funzionare nel cuore ischemico murino con maggiore successo in un autocrino rispetto al metodo paracrino. Questi risultati suggeriscono che la leptina può ridurre il danno ischemico modulando l’espressione genica all’interno del cuore coronarico.

Prova di una relazione tra leptina plasmatica , non Nesfatin-1, e desiderio nei maschi alcoldipendenti dopo l’astinenza.

Lo scopo di questa ricerca era scoprire se la leptina plasmatica , la nesfatin-1, il cortisolo, il problema neurotrofico di origine cerebrale (BDNF) e le citochine infiammatorie potrebbero essere utilizzati come potenziali biomarcatori per il diploma di craving all’interno del gruppo alcol-dipendente. malati dopo 1 mese di astinenza.

Sono stati valutati un totale di 83 pazienti con disfunzione da uso di alcol (AUD) e 61 argomenti salutari. I malati di AUD sono stati scelti dalla Divisione Dipendenza dai Materiali, Anhui Benessere Psicologico Cuore, e gli argomenti all’interno del gruppo di gestione sono stati scelti da volontari sani.

La scala del questionario sull’urgenza dell’alcol (AUQ) è stata utilizzata per giudicare l’entità del desiderio per l’alcol, e il controllo di screening dell’alcolismo del Michigan (MAST), il controllo di Fagerstrom per la dipendenza da nicotina (FTND), la scala di valutazione del nervosismo (SAS) e la Self-Score Despair Scale (SDS) è stata inoltre valutata in pazienti con AUD. Il saggio ELISA (Enzyme-Linked Immunosorbent Assay ) è stato utilizzato per la misurazione della leptina plasmatica , della nesfatin-1, del cortisolo, del BDNF, dell’interleuchina-6 (IL-6), della proteina C-reattiva (CRP) e del fattore di necrosi tumorale-α (TNF). -α) intervalli. Esaminare con controlli sani, la leptina comune , leptina /BMI, IL-6,Gli intervalli di PCR e TNF-α in chi soffre di AUD sono stati considerevolmente elevati, mentre gli intervalli di BDNF sono stati notevolmente ridotti.

Inoltre, la valutazione della correlazione parziale ha confermato che i punteggi AUQ dei soggetti alcoldipendenti sono stati correlati positivamente con i range di leptina plasmatica ( r = 0,613, P <0,001), relativamente alla nesfatina-1 ( r = 0,066, P = 0,569) dopo aver controllato l’età come covariata. Inoltre, è stato scoperto che gli intervalli plasmatici di nesfatin-1 sono correlati con i punteggi SDS ( r = 0,366, P = 0,001) all’interno del gruppo AUD. Inoltre, gli intervalli di leptina plasmatica sono stati correlati positivamente con IL-6 plasmatico ( r = 0,257, P = 0,033), CRP ( r = 0,305, P = 0,011) e TNF-α ( r = 0,311, P = 0,009) e correlata negativamente agli intervalli BDNF ( r = -0,245, P = 0,042) in chi soffre di AUD.

Questi risultati suggeriscono che la leptina plasmatica , ma non la nesfatin-1, possa essere un possibile biomarker per il diploma di craving in soggetti alcoldipendenti dopo 1 mese di astinenza, il cui meccanismo può essere associato alla disfunzione delle citochine infiammatorie e del BDNF intervalli.

Elevati intervalli di circolazione dell’attivatore del plasminogeno di tipo tissutale sono correlati alla minaccia di aborto spontaneo durante il primo trimestre di gravidanza.

L’aborto spontaneo è una complicanza standard nella gravidanza precoce, con un’incidenza del 20% circa. L’ecografia e la misurazione della gonadotropina corionica umana vengono utilizzate per determinare i malati vulnerabili all’aborto spontaneo; tuttavia, c’è un desiderio scientifico di cercare nuovi biomarcatori per determinare in modo prospettico i malati prima dell’inizio dei segni scientifici.

Proprio qui, ci proponiamo di analizzare potenziali biomarcatori di aborto spontaneo presi all’interno del primo appuntamento scientifico della gravidanza. Una ricerca caso-controllo è stata condotta principalmente sulla base di una coorte raccolta prospetticamente durante la quale i casi e i controlli sono stati stratificati retrospettivamente principalmente in base al risultato finale di gravidanza: gravidanze sane regolari (controlli = 33) e gravidanze che hanno portato ad aborto spontaneo (istanze = 10).

Abbiamo valutato le vescicole extracellulari isolate dalla precipitazione con ExoQuick™ e le concentrazioni proteiche di attivatore tissutale del plasminogeno, leptina e adiponectina misurate mediante ELISA . Le vescicole extracellulari hanno confermato la morfologia standard e le proteine di membrana: CD63, Alix e Flotilin-1. Le distribuzioni in scala delle vescicole extracellulari remote sono state di 112 ± 27 e 118 ± 28 nm di diametro rispettivamente per i controlli e per l’aborto spontaneo e l’intera quantità di vescicole extracellulari non presentava alcuna distinzione tra i controlli e il gruppo di aborto spontaneo.

Leptin ELISA Kit (Human) (OKBB00206)
OKBB00206	Aviva Systems Biology	96 Tests	EUR 606
Description: Description of target: Leptin (or obese, OB) is a circulating hormone that is expressed abundantly and specifically in the adipose tissue.1 Human ob protein is a 166-amino acid polypeptide with a putative signal sequence and is 84 and 83% homologous to the mouse and rat ob proteins, respectively.2 Northern blot analysis reveals that OB RNA is present at a high level in adipose tissue but at much lower levels in placenta and heart.3 Indeed, Leptin is first described as an adipocyte-derived signalling factor, which, after interaction with its receptors, induces a complex response including control of bodyweight and energy expenditure. Leptin seems in addition to its role in metabolic control to have important roles in reproduction and neuroendocrine signalling.4 Leptin is a powerful inhibitor of bone formation in vivo.5 Comparative mapping of mouse and human DNA indicates that the ob gene is located within a region of mouse chromosome 6 that is homologous to a portion of human chromosome 7q.3 The standard product used in this kit is recombinant human Leptin.;Species reactivity: Human;Application: ELISA;Assay info: ;Sensitivity: < 10 pg/mL
