Parkin is a cytosolic E3 ubiquitin ligase that plays an important role in neuroprotection by targeting several proteins to be degraded by the 26S proteasome. Its dysfunction has been associated not only with Parkinson's disease (PD) but also with other neurodegenerative pathologies, such as Alzheimer's disease and Huntington's disease. More recently, Parkin has been identified as a tumor suppressor gene implicated in cancer development. Due to the important roles that this E3 ubiquitin ligase plays in cellular homeostasis, its expression, activity, and turnover are tightly regulated. Several reviews have addressed Parkin regulation; however, genetic and epigenetic regulation have been excluded. In addition to posttranslational modifications (PTMs), this review examines the regulatory mechanisms that control Parkin function through gene expression, epigenetic regulation, and degradation. Furthermore, the consequences of disrupting these regulatory processes on human health are discussed.Multiple myeloma (MM) is a malignancy of antibody-producing plasma cells with genomic instability and genetic abnormality as its two hallmarks. Therefore, DNA damage is pervasive in MM cells, which indicates irregular DNA damage response (DDR) pathway. In this study, we demonstrated that LT-171-861, a multiple kinase inhibitor, could inhibit proliferation and induce apoptosis in MM cells. LT-171-861 promoted DDR pathway and triggered DNA damage through impeding the process of homologous recombination in double strand breaks, rather than directly elevating ROS level in MM cells. Mechanism research revealed that Pim2 inhibition was responsible for LT-171-861-indcued DNA damage and cell apoptosis. LT-171-861 mainly suppressed Pim2 kinase activity and reduced the expression of its phosphorylated substrates, such as 4EBP1 and BAD. Moreover, Olaparib, a PARP inhibitor, could enhance the antitumor effect of LT-171-861 in suppressing tumor growth in MM xenografted nude mice. Taken together, our results demonstrated that LT-171-861 showed a promising therapeutic potential for MM and had an additional lethal effect with PARP inhibitors.Statins reduce cardiovascular complications in patients with high LDL-cholesterol but are associated with myopathy. We compared the toxicity of simvastatin of C2C12 myoblasts and myotubes. Since myoblasts can proliferate and fuse to myotubes, myoblasts can be considered as satellite cells and myotubes as mature muscle fibers. Simvastatin increased plasma membrane permeability and decreased the cellular ATP content in both myoblasts and myotubes, but with a stronger effect on myoblasts. While insulin prevented cytotoxicity up to 8 h after addition of simvastatin to myotubes, prevention in myoblasts required simultaneous addition. Mevalonate and geranylgeraniol prevented simvastatin-associated cytotoxicity in both myoblasts and myotubes. Simvastatin impaired the phosphorylation of the insulin receptor (IR β), Akt ser473 and S6rp, and increased phosphorylation of AMPK thr172 in both myotubes and myoblasts, which was prevented by insulin and mevalonate. Simvastatin impaired oxygen consumption and increased superoxide production by myoblasts and myotubes and induced apoptosis via cytochrome c release. In addition, simvastatin impaired proliferation and fusion of myoblasts to myotubes by inhibiting the expression of the nuclear transcription factor MyoD and of the metalloprotease ADAM-12. Decreased expression of the proliferation factor Ki-67 and of ADAM-12 were also observed in gastrocnemius of mice treated with simvastatin. In conclusion, myoblasts were more susceptible to the toxic effects of simvastatin and simvastatin impaired myoblast proliferation and myotube formation. Impaired muscle regeneration may represent a new mechanism of statin myotoxicity.Human gut bacterial strains can co-exist with their hosts for decades, but little is known about how these microbes persist and disperse, and evolve thereby. Here, we examined these processes in 5,278 adult and infant fecal metagenomes, longitudinally sampled in individuals and families. Our analyses revealed that a subset of gut species is extremely persistent in individuals, families, and geographic regions, represented often by locally successful strains of the phylum Bacteroidota. These "tenacious" bacteria show high levels of genetic adaptation to the human host but a high probability of loss upon antibiotic interventions. By contrast, heredipersistent bacteria, notably Firmicutes, often rely on dispersal strategies with weak phylogeographic patterns but strong family transmissions, likely related to sporulation. These analyses describe how different dispersal strategies can lead to the long-term persistence of human gut microbes with implications for gut flora modulations.
To generate regional, residential, and nationally representative estimates of knowledge of abortion legality and availability among women of reproductive age in Ethiopia, and examine how knowledge varies across regions and by urban/rural residence.

Our study draws on data from a nationally representative, cross-sectional survey implemented in 2019 in each of Ethiopia's regional and administrative states, yielding a sample of 8,837 women aged 15-49. We compare weighted estimates and regional distributions of three outcomes 1) general awareness and 2) correct knowledge of the abortion law, and 3) knowledge of facility-based abortion service availability.

Significant regional and urban/rural disparities in knowledge of abortion legality and availability exist. Nationally, 27% of women are aware of the abortion law and just 5% of women have comprehensive knowledge of the law, while 30% know where to access facility-based abortion services. Regionally, estimates range significantly, from 2% in Somali to 45% abortion is available for multiple indications. Efforts to improve knowledge of abortion legality and availability are needed, and should be locally tailored to address regional inequities.
Existing clinical practice guidelines for carriers of pathogenic variants of DNA mismatch repair genes (Lynch syndrome) are based on the mean age-specific cumulative risk (penetrance) of colorectal cancer for all carriers of pathogenic variants in the same gene. We aimed to estimate the variation in the penetrance of colorectal cancer between carriers of pathogenic variants in the same gene by sex and continent of residence.

In this retrospective cohort study, we sourced data from the International Mismatch Repair Consortium, which comprises 273 members from 122 research centres or clinics in 32 countries from six continents who are involved in Lynch syndrome research. Families with at least three members and at least one confirmed carrier of a pathogenic or likely pathogenic variant in a DNA mismatch repair gene (MLH1, MSH2, MSH6, or PMS2) were included. Inflammation chemical The families of probands with known de-novo pathogenic variants were excluded. Data were collected on the method of ascertainment of the family, sex, carrier status, cancer diagnoses, and ages at the time of pedigree collection and at last contact or death.
