2019-09-20
In general, cellular senescence is considered a programmed response to stress that can be activated by oxidative stress, irradiation or action of substances or drugs. These stressors cause DNA damage and, through the action of specific proteins (p53 and p21), lead to cell senescence (di Fagagna, 200

In conclusion, as illustrated in Fig. 5G, in response to MNNG-induced DNA damage, PARP-1 appears to have dual roles in determining the cell fate in response to MNNG: PARP-1 activation is the cause of non-apoptotic cell death via ATP depletion and PARP-1 activation is able to elicit a self-protective

The genomic DNA sequences of CXCL8 and CXCRs were retrieved from the fugu genome database v4.0. The intron–exon boundaries were identified with the corresponding cDNA sequences. This comparison revealed that the fugu gene is about 1.13kb long and contains four exons separated by three introns (top

2019-09-20
To better understand the mechanism of splicing in CLCN1, we began by constructing a minigene spanning exons 5–7 of CLCN1, resulting in the synthetic CLCN1 (5–7) minigene. We also established a new assay using real-time reverse transcription (RT)-PCR, which can distinguish between splicing variants b

It is well known that acrolein, a metabolite of cyclophosphamide, is responsible for the cyclophosphamide-induced cystitis, and that acrolein is capable of activating TRPA1 channels expressed in the capsaicin-sensitive primary afferents [2], [11]. In this context, it is likely that the early phase o

Resistance to SP is linked to point mutations that accumulate at several sites in the dihydrofolate reductase (dhfr) and dihydropteroate synthase (dhps) aphidicolin of P. falciparum (Roper et al., 2003). These mutations have been identified in codons 16, 51, 59, 108, and 164 in the dhfr gene and co

Concluding remarks A crucial step in the microbial degradation of steroids is the 1(2)-dehydrogenation of the steroid nucleus by FAD-dependent Δ1-KSTDs. This step is required to initiate the opening of the steroid nucleus under both aerobic and anaerobic conditions. A large variety of steroid-deg

The most important cytotoxic lesion formed by the nitrogen mustards is generally considered to be the DNA–DNA interstrand cross-link 12, 13. DNA–DNA interstrand cross-links are thought to exert their cytotoxic effects by inhibiting DNA duplex strand separation, progression of the Cathepsin S inhibit

Results and discussion Conclusion We have constructed a series of potent and greatly selective DPP-4 inhibitors with pyrazolo[1,5-a]pyrimidin-7(4H)-one core surrogates. The modification of the core led us to b2 which has IC50 of 80 nM and > 1000 fold selectivity over DPP-8 and DPP-9. We utiliz

Methods Results Discussion Preclinical data indicate that nepicastat modulates sympathetic drive to the gpr120 agonist with a mild pressor effect in various animal models of hypertension (Stanney et al., 1998). However in this clinical study, the doses of nepicastat employed did not signifi

The DNA damage response (DDR) is a cellular mechanism that protects against DNA damage induced by endogenous and exogenous factors, it includes changes in cellular processes such as BQ-123 clinical regulation, DNA damage repair, apoptosis and chromatin remodeling. In recent years, the DDR has been r

The authentic PPase was purified from B. subtilis as described previously [21], whereas the recombinant enzyme was purified to homogeneity from E. coli by a simplified procedure including only phenyl-Sepharose CL-4B column chromatography and DEAE-HPLC [21]. About 26 mg of pure enzyme was obtained fr

RNA-sequencing (RNA-seq) is a particularly effective technology for gene discovery in a given process, especially in non-model species for which reference genome sequences are not available.
