40. 95% CI -3.03-3.83, P = 0.82), postoperative complications (RR 1.41. 95% CI 0.76-2.63, P = 0.28), or recurrence (RR 2.33, 95% CI 0.48-11.44, P = 0.30). SG for RGC tended to be correlated with favorable 5-year overall survival; however, the association was not statistically significant (HR 0.89, 95% CI 0.63-1.26, P = 0.51).

Organ-preserving approaches such as SG may be a safe and feasible treatment option for early-stage RGC.

We hypothesized that parkin cysteines participate in redox reactions and that these are reflected in its posttranslational modifications. We found that in post mortem human brain, including in the Substantia nigra, parkin is largely insoluble after age 40 years; this transition is linked to its oxidation, such as at residues Cys95 and Cys253. In mice, oxidative stress induces posttranslational modifications of parkin cysteines that lower its solubility in vivo. Similarly, oxidation of recombinant parkin by hydrogen peroxide (H2O2) promotes its insolubility and aggregate formation, and in exchange leads to the reduction of H2O2. This thiol-based redox activity is diminished by parkin point mutants, e.g., p.C431F and p.G328E. In prkn-null mice, H2O2 levels are increased under oxidative stress conditions, such as acutely by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine toxin exposure or chronically these complementary redox effects may augment oxidative stress during ageing in dopamine-producing cells of mutant PRKN allele carriers, thereby enhancing the risk of Parkinson's-linked neurodegeneration.

This review considers the framework of high-risk vs. population approaches as proposed in the Rose's axiom within the context of cardiovascular diseases, including its benefits and limitations. We also contextualize the use of precision medicine in primary prevention therapy and contrast that with population approach.

Although the high-risk strategy aims at individualized care, the complexity of pharmacologic regimens and other limitations reduces its real-life impact. On the other hand, broad population strategies include treatment of a substantial number of low-risk individuals who are unlikely to benefit from treatment. The use of additional strategies to identify those low-risk individuals, instead of targeting at identifying the high-risk population, is and alternative strategy to be considered. Evidence of the potential use of coronary artery calcium score and polypills for this strategy is discussed. A more targeted population approach to primary prevention in cardiovascular diseases with the use of polypills and coronary artery calcium score might be considered in a structured mass-strategy approach to risk reduction.

All RecJ proteins are known to date only perform exonuclease activity. The present study reports that a novel RecJ protein obtained from Bacillus cereus isolated from marine sediments has both endonuclease and exonuclease activities.

Analysis of the BcRecJ expression induction in E. coli BL21 revealed that the BcRecJ protein cleaved plasmids and genomic DNA in the host cell, and led to cell death and decreased the DNA content. Further, the BcRecJ protein had the ability to degrade supercoiled plasmid DNA into circular or linear forms in vitro. Meanwhile, the BcRecJ protein loaded with an S-modified guide facilitated plasmid linearization and reduced smear formation.

The results suggested that this novel BcRecJ protein was different from any reported RecJs and had a longer C-terminus. Testing the BcRecJ mutants indicated that the endonuclease activity was affected by two residues of BcRecJ (D561, E637) after testing the BcRecJ mutants.

The discovery of the type of protein is a new breakthrough for the RecJ proteins, which has both endonuclease and exonuclease activities.

Tripartite motif 32 (TRIM32) is a member of TRIM family that has been found to be involved in cardiovascular disease. However, the role of TRIM32 in PAH remains unclear. Here we investigated the effects of TRIM32 on hypoxia-induced pulmonary artery smooth muscle cells (PASMCs) in vitro. Our results showed that TRIM32 protein level in the plasma samples from PAH patients was decreased as compared with healthy volunteers. Exposure to hypoxia condition caused a significant decrease in TRIM32 expression in PASMCs. Overexpression of TRIM32 inhibited hypoxia-induced proliferation and migration of PASMCs. TRIM32 overexpression elevated the increased apoptotic rate and caspase-3 activity in hypoxia-induced PASMCs. Moreover, overexpression of TRIM32 reversed hypoxia-induced down-regulation of myocardin, SM 22 and calponin, as well as up-regulation of osteopontin (OPN). Whereas, TRIM32 knockdown shwed the opposite effect. Furthermore, overexpression of TRIM32 inhibited hypoxia-induced activation of PI3K/Akt with decreased phosphorylated level of PI3K and Akt. Additionally, activation of PI3K/Akt by IGF-1 treatment reversed the effects of TRIM32 on hypoxia-induced PASMCs. In conclusion, these findings indicated that TRIM32 was involved in the development of PAH through regulating the proliferation, migration, apoptosis and dedifferentiation of PASMCs, which might be mediated by the PI3K/Akt signaling pathway. Thus, TRIM32 might be a potential target for PAH treatment.
