Ulk1 is a key autophagy protein. Here, we tested expression and potential function of Ulk1 in human gastric cancer. Ulk1 mRNA and protein were significantly elevated in multiple fresh human gastric cancer tissues. Its level was relatively low in surrounding normal epithelial tissues. Ulk1 over-expression was also observed in several gastric cancer cell(More)
UNLABELLED To further explore the relationship between hypertrophic scar and injury to conical structure of skin and the pathogenesis of hypertrophic scar, and to reproduce an optimal animal model of hypertrophic scar. METHODS The back of two FRDP pigs were shaved, and a piece of normal skin was harvested for the observation of conical structure of skin.(More)
AIM To generate M2AChR-Gi1alpha fusion protein in baculovirus-Sf9 cells system and detect the effects of various muscarinic ligands and magnesium ion on the interaction of fused M2AChR and Gi1alpha. METHODS M2AChR-Gi1alpha fused DNA was generated in a two step polymerase chain reaction (PCR) and then expressed in Sf9 cells to produce fusion protein. [3H](More)
Currently, the clinical management of visceral pain remains unsatisfactory for many patients suffering from this disease. While preliminary animal studies have suggested the effectiveness of gabapentin in successfully treating visceral pain, the mechanism underlying its analgesic effect remains unclear. Evidence from other studies has demonstrated the(More)
Hypoxic preconditioning activates endogenous mechanisms that protect against cerebral ischemic and hypoxic injury. To better understand these protective mechanisms, adult rats were housed in a hypoxic environment (8% O2/92% N2) for 3 hours, and then in a normal oxygen environment for 12 hours. Their cerebrospinal fluid was obtained to culture cortical(More)
