“…By contrast, IRS-2 is mainly located in the peripheral region of the pancreatic islets and at low levels in β-cells, and positively moderates the compensation mechanism of β-cells ( 9 ). In terms of regulatory mechanisms, IRS-1 is activated through the activation of PI3K and calcium channels, among others, while IRS-2 is activated by PI3K, MAPK, Ras and other pathways, and they ultimately modulate the growth, proliferation and mitosis of β-cells ( 10 , 11 ).…”

“…Finally, there has been dispute regarding the interplay between protein metabolism and the related signaling pathways of β-cell proliferation. Chen et al ( 13 ) argued that FOXO1 may inhibit the expression of albumin, while other proteins such as phycocyanin have been demonstrated to promote β-cell proliferation by regulating PI3K-AKT signaling and downstream FOXO1, and ameliorate diabetes mice by stimulating glucokinase expression and insulin signaling in the pancreas ( 11 , 31 ). It has also been reported that Exendin-4 may enhance β-cell proliferation in some instances by stimulating PI3K-AKT signaling, potentially via an intermediate ligand-binding activation step involving corresponding receptors ( 14 ).…”

“…In addition, the literature provides some evidence on the in vivo hypoglycemic activity exerted by C-PC peptides in different animal models [11,12]. In particular, a recent study has shown that C-PC peptides activate the insulin signaling pathway and glucokinase expression in the pancreas and liver of diabetic mice [13]. Moreover, the treatment of insulin-secreting INS-1 β-cells, a common model for diabetes research, with C-PC peptides induces an interesting protective mechanism [14].…”

“…Otro de los estudios de la ficocianina de la espirulina se realizó con ratones diabéticos inducidos por aloxano que fueron suplementados con ficocianina de la espirulina, por 4 semanas, con dosis de 100 y 200 mg/kg de peso corporal, donde se evaluó los niveles de glucosa, proteína de suero glicosilada, Hb1Ac y niveles de insulina en ayunas. El tratamiento con ficocianina mejoró el nivel de glucoquinasa (GK) en el hígado y el páncreas, y el nivel de la proteína reguladora de glucoquinasa (GKRP) en el hígado, en donde se muestra que la ficocianina mejora la diabetes mellitus inducida por aloxano en ratones , mediante la activación de la vía de señalización de insulina y la expresión de GK en páncreas e hígado (122) .…”

“…Este efecto podría deberse a la ficocianina presente en la espirulina, como lo explica una estudio experimental en ratones diabéticos inducidos por aloxano. En los que se midió glucosa e insulina en ayunas, hemoglobina y proteína de suero glicosilada, y con ello se obtuvo que la ficocianina mejora la diabetes mellitus en estos ratones mediante la activación de la expresión de glucoquinasa y señalización de insulina en páncreas e hígado de los roedores (122) . Esta expresión incrementaría la síntesis de glucógeno hepático, lo que explicaría su función reductora de glucosa en sangre, pues se utilizó antes de ser inyectados con aloxano (121) .…”
