AGEs promoted late EPC apoptosis.
Using RT-PCR and ELISA assays, we show that AGEs promoted the levels of mRNA and secretion significantly in macrophages.
It can be speculated that because AGEs promote inflammation, early build-up of AGE stores may start undermining innate defenses from childhood.
These findings are consistent with evidence showing that excessive food AGEs promote inflammation and OS in humans (9, 19) and IR in mice (15, 16).
Recent studies have shown that AGEs promote EPC apoptosis, inhibit EPC proliferation, and impair EPC functions such as migration, adhesion and tube-forming ability [ 16, 17].
Western blot analysis of the AGE-treated HUVECs demonstrated that AGEs promoted the expression of the receptor for advanced glycation end product (RAGE), which is usually promoted by and bound to AGEs [ 49, 50].
Direct evidence that oral AGEs promote OS and cause metabolic changes was provided by studies of mice that were pair fed a low-AGE diet or the same diet supplemented with a well defined AGE (methylglyoxal [MG]-BSA) (16).
Recent studies indicated that advanced glycation end products (AGEs) promoted EPC apoptosis [ 26], and long-term exposure to high glucose may enhance cellular senescence and reduce cell numbers and functional competencies of EPCs via NO-related mechanisms [ 10].
Yet, the drier and cooler environment during the ice ages promoted the expansion of open scrub environments in southern Brazil, including the sand dune areas along the Atlantic coast [ 20, 46].
Mobile coupons — usually text messages with discount codes sent to a cellphone — are becoming the blue-light specials for the digital age, promoting last-minute clothing sales, two-for-one entrees and cheap tickets to the theater.
The mechanism of calcium intake into bones during growth led to calcium deposition in blood vessels after middle age, promoting atherosclerosis.
