Nanomaterials obtained by green synthesis technologies have been widely studied in recent years owing to constitute cost-effective and environmental-friendly methods. In addition, there are several works that report the simultaneous performance of the reducer agent as a functionalizing agent,...

Hyperphosphatemia-Induced Oxidant/Antioxidant Imbalance Impairs Vascular Relaxation and Induces Inflammation and Fibrosis in Old Mice.

Antioxidants (Basel, Switzerland)

Asenjo-Bueno A, Alcalde-Estévez E, El Assar M, Olmos G, Plaza P, Sosa P, Martínez-Miguel P, Ruiz-Torres MP, López-Ongil S.
PMID: 34439556
Antioxidants (Basel). 2021 Aug 19;10(8). doi: 10.3390/antiox10081308.

Aging impairs vascular function, but the mechanisms involved are unknown. The aim of this study was to analyze whether aging-related hyperphosphatemia is implied in this effect by elucidating the role of oxidative stress. C57BL6 mice that were aged 5...

Macrophage-mediated RON signaling supports breast cancer growth and progression through modulation of IL-35.

Oncogene

Ruiz-Torres SJ, Bourn JR, Benight NM, Hunt BG, Lester C, Waltz SE.

Tumor associated macrophages (TAMs) play a major role in regulating mammary tumor growth and in directing the responses of tumor infiltrating leukocytes in the microenvironment. However, macrophage-specific mechanisms regulating the interactions of macrophages with tumor cells and other leukocytes...
