Minor effects of green tea catechin supplementation on cardiovascular risk markers in active older people: a randomized controlled trial.

Aim: Although previous studies have shown that consumption of green tea catechins (GTC) and walking might prevent development of cardiovascular disease (CVD), the effects of GTC supplementation on CVD risk in active older people are unknown.

Methods: A total of 52 older adults (male/female 20/32, mean age 69.1 ± 5.

The role of VAMP7/TI-VAMP in cell polarity and lysosomal exocytosis in vivo.

VAMP7 or tetanus neurotoxin-insensitive vesicle- associated membrane protein (TI-VAMP) has been proposed to regulate apical transport in polarized epithelial cells, axonal transport in neurons and lysosomal exocytosis. To investigate the function of VAMP7 in vivo, we generated VAMP7 knockout mice. Here, we show that VAMP7 knockout mice are indistinguishable from control mice and display a similar localization of apical proteins in the kidney and small intestine and a similar localization of axonal proteins in the nervous system.
