    • Altered GH-IGF-1 axis in severe obese subjects is reversed after bariatric surgery-induced weight loss and related with low-grade chronic inflammation 

      Juiz-Valiña, Paula; Pena-Bello, Lara; Cordido, María; Outeiriño-Blanco, Elena; Pértega-Díaz, Sonia; Varela-Rodríguez, Bárbara María; García-Brao, María Jesús; Mena, Enrique; Sangiao-Alvarellos, Susana; Cordido, Fernando (MDPI, 2020-08-12)
      [Abstract] Endocrine disorders are common in obesity, including altered somatotropic axis. Obesity is characterized by reduced growth hormone (GH) secretion, although the insulin-like growth factor-1 (IGF-1) values are ...

    • Beneficial effects of bariatric surgery-induced by weight loss on the proteome of abdominal subcutaneous adipose tissue 

      Varela-Rodríguez, Bárbara María; Juiz-Valiña, Paula; Varela, Luis; Outeiriño-Blanco, Elena; García-Brao, María Jesús; Mena, Enrique; Noguera, José Francisco; Valero-Gasalla, Javier; Cordido, Fernando; Sangiao-Alvarellos, Susana; Bravo, Susana Belén (MDPI, 2020-01-13)
      [Abstract] Bariatric surgery (BS) is the most effective treatment for obesity and has a positive impact on cardiometabolic risk and in the remission of type 2 diabetes. Following BS, the majority of fat mass is lost from ...

    • Central resistance to thyroid hormones in morbidly obese subjects is reversed after bariatric surgery-induced weight loss 

      Juiz-Valiña, Paula; Cordido, María; Outeiriño-Blanco, Elena; Pértega-Díaz, Sonia; Varela-Rodríguez, Bárbara María; García-Brao, María Jesús; Mena, Enrique; Pena-Bello, Lara; Sangiao-Alvarellos, Susana; Cordido, Fernando (MDPI, 2020-01-28)
      [Abstract] Endocrine abnormalities are common in obesity, including altered thyroid function. The altered thyroid function of obesity may be due to a mild acquired resistance to the thyroid hormone. The aim of this study ...

    • Circulating levels of irisin in hypopituitary and normal subjects 

      Pena-Bello, Lara; Pértega-Díaz, Sonia; Sangiao-Alvarellos, Susana; Outeiriño-Blanco, Elena; Eiras-Leal, Raquel; Varela-Rodríguez, Bárbara María; Juiz-Valiña, Paula; Pérez-Fontán, Miguel; Cordido, María; Cordido, Fernando (PLoS ONE, 2016-07-29)
      [Abstract] Context. The recently identified myokine irisin conveys some of the benefits of exercise. Hypopituitarism with adult growth hormone deficiency (HP) is a situation characterized by decreased GH secretion and an ...

    • Effect of weight loss after bariatric surgery on thyroid-stimulating hormone levels in euthyroid patients with morbid obesity 

      Juiz-Valiña, Paula; Outeiriño-Blanco, Elena; Pértega-Díaz, Sonia; Varela-Rodríguez, Bárbara María; García-Brao, María Jesús; Mena, Enrique; Pena-Bello, Lara; Cordido, María; Sangiao-Alvarellos, Susana; Cordido, Fernando (MDPI, 2019-05-20)
      [Abstract] Obesity is associated with several endocrine abnormalities, including thyroid dysfunction. The objective of this study was to investigate the effect of weight loss after bariatric surgery on thyroid-stimulating ...

    • FNDC5 expression and circulating irisin levels are modified by diet and hormonal conditions in hypothalamus, adipose tissue and muscle 

      Varela-Rodríguez, Bárbara María; Pena-Bello, Lara; Juiz-Valiña, Paula; Vidal Bretal, Beatriz; Cordido, Fernando; Sangiao-Alvarellos, Susana (Nature, 2016-07-19)
      [Abstract] Irisin is processed from fibronectin type III domain-containing protein 5 (FNDC5). However, a controversy exists concerning irisin origin, regulation and function. To elucidate the relationship between serum ...

    • Glucose and lipid dysmetabolism in a rat model of prediabetes induced by a high-sucrose diet 

      Burgeiro, Ana; Cerqueira, Manuela G.; Varela-Rodríguez, Bárbara María; Nunes, Sara; Neto, Paula; Pereira, Frederico C.; Reis, Flávio; Carvalho, Eugénia (Multidisciplinary Dixital Publishing Institute, 2017-06-21)
      [Abstract] Glucotoxicity and lipotoxicity are key features of type 2 diabetes mellitus, but their molecular nature during the early stages of the disease remains to be elucidated. We aimed to characterize glucose and lipid ...
