13. Propranolol inhibits the proliferation, migration and tube formation of hemangioma cells through HIF-1α dependent mechanisms
The aim of this study was to investigate the mechanism of propranolol on the regression of hemangiomas. Propranolol-treated hemangioma tissues were collected and the expression of hypoxia inducible factor-1α (HIF-1α) was examined. We also established HIF-1α overexpression and knockdown hemangioma cells, and determined the effects of HIF-1α on the hemangi

14. A EXPRESSÃO DO GENE ANKRD1 CORRELACIONA-SE COM O STATUS DE BIÓPSIAS MUSCULARES EM ADULTOS PORTADORES DE DERMATOMIOSITE SEM EXPOSIÇÃO PRÉVIA A TRATAMENTO
OBJETIVOS: ANKRD1 codifica "ankyrin repeat domain containing protein 1" e tem um papel importante na miogênese e possivelmente também na angiogênese. Microvasculopatia é considerada como um ponto central e uma alteração patológica precoce na dermatomiosite (DM), levando à hipóxia e à atrofia perifascicular muscular. Estas alterações poderiam est

15. Impact of extracellular alkalinization on the survival of human CD24-/CD44+ breast cancer stem cells associated with cellular metabolic shifts
Cancer stem cells reside in a distinct region within the tumor microenvironment that it is believed to play a fundamental role in regulating stemness, proliferation, survival, and metabolism of cancer cells. This study aimed to analyze the effect of extracellular alkalinization on metabolism and survival of human CD24-/CD44+ breast cancer stem cells (BCSCs).

16. Analysis of various potential prognostic markers and survival data in clear cell renal cell carcinoma
ABSTRACT Purpose Clear cell renal cell cancers frequently harbor Von Hippel-Lindau gene mutations, leading to stabilization of the hypoxia-inducible factors (HIFs) and their target genes. In this study, we investigated the relationship between vascular endothelial growth factor (VEGF), HIF-1α, HIF-2α, p53 positivity, microvessel density, and Ki-67 rates

17. Ras oncogene and Hypoxia-inducible factor-1 alpha (hif-1α) expression in the Amazon fish Colossoma macropomum (Cuvier, 1818) exposed to benzo[a]pyrene.
Abstract Benzo[a]pyrene (B[a]P) is a petroleum derivative capable of inducing cancer in human and animals. In this work, under laboratory conditions, we analyzed the responses of Colossoma macropomum to B[a]P acute exposure through intraperitoneal injection of four different B[a]P concentrations (4, 8, 16 and 32 μmol/kg) or corn oil (control group). We anal

18. Effects of curcumin on growth of human cervical cancer xenograft in nude mice and underlying mechanism
Abstract The present study investigated the effects of curcumin (Cur) on growth of human cervical cancer xenograft in nude mice and underlying mechanism. The nude mice modeled with human cervical cancer HeLa cell xenograft were treated with normal saline (control), 3 mg/kg Cisplatin, 50, 100 and 200 mg/kg Cur, respectively. The animal body weight and growth

19. Papel da via de sinalização do HIF-1α na osteoartrite: revisão sistemática
Resumo A osteoartrite (OA) é a forma mais comum de artrite e frequentemente é diagnosticada e gerenciada na atenção primária; é caracterizada por perda da cartilagem articular hialina, um tecido conjuntivo único que fisiologicamente carece de vasos sanguíneos. A cartilagem articular sobrevive em um microambiente desprovido de oxigênio, que é regula

20. Expression of myogenes in longissimus dorsi muscle during prenatal development in commercial and local Piau pigs
Abstract This study used qRT-PCR to examine variation in the expression of 13 myogenes during muscle development in four prenatal periods (21, 40, 70 and 90 days post-insemination) in commercial (the three-way Duroc, Landrace and Large-White cross) and local Piau pig breeds that differ in muscle mass. There was no variation in the expression of the CHD8, EID

21. Quercetin alleviates pulmonary angiogenesis in a rat model of hepatopulmonary syndrome
Quercetin shows protective effects against hepatopulmonary syndrome (HPS), as demonstrated in a rat model. However, whether these effects involve pulmonary vascular angiogenesis in HPS remains unclear. Therefore, this study aimed to assess the effect of quercetin on pulmonary vascular angiogenesis and explore the underlying mechanisms. Male Sprague-Dawley ra

22. Immunoexpression of HIF-1α and VEGF in Periodontal Disease and Healthy Gingival Tissues
Resumo O fator induzível por hipóxia 1 alfa (HIF-1α) e o fator de crescimento endotelial vascular (VEGF) são proteínas que estimulam a proliferação e a migração de células endoteliais. Estas proteínas têm sido descritas em muitas condições patológicas e inflamatórias, mas o envolvimento dessas no desenvolvimento de periodontite não foi compl

23. Regulating Effect Of Carnosine And /Or L- Arginine On The Expression Of Inflammatory Molecules Induced Nephropathy In The Hypoxic Rat Model
This study aimed to explore the effective role of carnosine and /or L- arginine in down regulation of the inflammatory molecule expression caused renal damage in response to sodium nitrite (NaNO2) induced hypoxia in rats . NaNO2 was administered subcutaneously (s.c.) to rats as a single dose (60 mg/kg body weight ). L-arginine (200mg/Kg body weight) and carn

24. Inflammation induced by increased frequency of intermittent hypoxia is attenuated by tempol administration
The levels of serum inflammatory cytokines and the activation of nuclear factor kappa B (NF-κB) and hypoxia inducible factor-1α (HIF-1α) in heart tissues in response to different frequencies of intermittent hypoxia (IH) and the antioxidant tempol were evaluated. Wistar rats (64 males, 200-220 g) were randomly divided into 6 experimental groups and 2 contr
