Substance P, acting via its neurokinin 1 receptor (NK1 R), plays an important role in mediating a variety of inflammatory processes. Its interaction with chemokines is known to play a crucial role in the pathogenesis of acute pancreatitis. In pancreatic acinar cells, substance P stimulates the release of NFkappaB-driven chemokines. However, the signal(More)
Leg lengthening procedure is used increasingly to treat leg length discrepancy and some forms of dwarfism. We investigated adaptation in rat sciatic nerve to the gradual nerve elongation that occurs with leg lengthening. Indirect nerve elongation was produced by leg lengthening by a total of 15, 30, 45, or 70 mm at a rate of 1 mm/day. One day after leg(More)
The neuropeptide substance P (SP), as a major mediator of neuroimmunomodulatory activity, modulates diverse functions of immune cells, including macrophages. In the current study, we focused on the yet uncertain role of SP in enhancing the inducible/inflammatory chemokine response of macrophages and the signaling mechanism involved. We studied the effect on(More)
Resveratrol is an important antioxidant that confers several beneficial effects on human health. 4-coumarate coenzyme A ligase (4CL) and resveratrol synthase (RS) are key rate-limiting enzymes in the biosynthetic pathway of resveratrol. Using gene fusion technology, the fusion gene, 4CL::RS, was constructed by the 4CL gene from Arabidopsis thaliana and RS(More)
Neuropeptides play an important role in the active communication between the nervous and immune systems. Substance P (SP) is a prominent neuropeptide involved in neurogenic inflammation and has been reported to exert various proinflammatory actions on inflammatory leukocytes including neutrophils. The present study further investigated the modulatory effect(More)
We have earlier shown that mouse pancreatic acinar cells produce hydrogen sulfide (H(2)S), which plays a key role in the pathogenesis of acute pancreatitis (AP). H(2)S-dependent induction of inflammation is mediated by the activation of transcription factor NF-kappaB. We now provide evidence that activation of Src family kinases (SFKs) is crucial in(More)
Substance P, a neuropeptide belonging to the tachykinin family is a pleiotropic peptide with specific neural activities and involved in immunomodulation and antimicrobial host defense. It has been found to modulate a variety of inflammatory processes, including acute pancreatitis, sepsis, systemic inflammatory response syndrome and asthma. Also notably,(More)
Interest in the antioxidant activity of bamboo leaves is growing. To discover new sources of natural antioxidants, a TLC bioautography method combined with a new image processing method was developed to evaluate the antioxidant activity of leaf extracts from 15 different species of bamboo. The results showed that the methanolic extract of Bambusa. textilis(More)
Recent evidence has revealed that senescence induction requires fine-tuned activation of p53, however, mechanisms underlying the regulation of p53 activity during senescence have not as yet been clearly established. We demonstrate here that SCF(Fbxo22)-KDM4A is a senescence-associated E3 ligase targeting methylated p53 for degradation. We find that Fbxo22(More)
