Many biological processes involve precise cellular state transitions controlled by complex gene regulation. Here, we use budding yeast cell cycle as a model system and explore how a gene regulatory circuit encodes essential information of state transitions. selleck products We present a generalized random circuit perturbation method for circuits containing heterogeneous regulation types and its usage to analyze both steady and oscillatory states from an ensemble of circuit models with random kinetic parameters. The stable steady states form robust clusters with a circular structure that are associated with cell cycle phases. This circular structure in the clusters is consistent with single-cell RNA sequencing data. The oscillatory states specify the irreversible state transitions along cell cycle progression. Furthermore, we identify possible mechanisms to understand the irreversible state transitions from the steady states. We expect this approach to be robust and generally applicable to unbiasedly predict dynamical transitions of a gene regulatory circuit.Epigenetic deregulation of gene transcription is central to cancer cell plasticity and malignant progression but remains poorly understood. We found that the uncharacterized epigenetic factor chromodomain on Y-like 2 (CDYL2) is commonly over-expressed in breast cancer, and that high CDYL2 levels correlate with poor prognosis. Supporting a functional role for CDYL2 in malignancy, it positively regulated breast cancer cell migration, invasion, stem-like phenotypes, and epithelial-to-mesenchymal transition. CDYL2 regulation of these plasticity-associated processes depended on signaling via p65/NF-κB and STAT3. This, in turn, was downstream of CDYL2 regulation of MIR124 gene transcription. CDYL2 co-immunoprecipitated with G9a/EHMT2 and GLP/EHMT1 and regulated the chromatin enrichment of G9a and EZH2 at MIR124 genes. We propose that CDYL2 contributes to poor prognosis in breast cancer by recruiting G9a and EZH2 to epigenetically repress MIR124 genes, thereby promoting NF-κB and STAT3 signaling, as well as downstream cancer cell plasticity and malignant progression.Over the past decades, asymmetric catalysis has been intensely investigated as a powerful tool for the preparation of numerous chiral biologically active compounds. However, developing general and practical strategies for preparation of both enantiomers of a chiral molecule via asymmetric catalysis is still a challenge, particularly when the two enantiomers of a chiral catalyst are not easily prepared from natural chiral sources. Inspired by the biologic system, we report herein an unprecedented catalytic enantiodivergent Michael addition of pyridazinones to enones by subtle adjustment of achiral amino moiety of dipeptide phosphine catalysts. These two dipeptide phosphine catalysts, P5 and P8, could deliver both enantiomers of a series of N2-alkylpyridazinones in good yields (up to 99%) with high enantioselectivities (up to 99% ee) via the catalyst-controlled enantiodivergent addition of pyridazinones to enones.We demonstrate the nearly quantitative conversion of methanol to methyl formate (MF) with a reliable durability on the reduced-graphene-oxide-confined VTiOx nanoparticles (rGO@VTiO). The rGO@VTiO exhibits superior low-temperature reactivity than the rGO-free VTiO, and the MF yield of 98.8% is even comparable with the noble metal catalysts. Both experiments and simulations demonstrate that the ultrathin rGO shell significantly impacts the shell/core interfacial electronic structure and the surface chemistry of the resultant catalysts, leading to remarkable reactivity in methanol to MF. rGO enhances the dispersion and loading rates of active monomeric/oligomeric VOx. In particular, the electron migration between the rGO shell and oxides core reinforces the acidity of rGO@VTiO in the absence of sulfate acidic sites. Moreover, both in situ NAP-XPS and DRIFTS investigations suggest that the lattice oxygen was involved in the oxidation of methanol and the MF was formed via the hemiacetal mechanism.Background While gait assessments are recommended to evaluate fall risk in older adults, these often involve walking in a straight line, even though one-third of steps taken throughout the day involve turning. Falls that occur during a turn tend to be more serious than falls that occur during a straight walk, but little is known about how gait variables collected during a turn can predict falls. Research question How do gait characteristics collected from straight and turning walking phases predict falls in older adults? Methods We prospectively examined the association between six quantitative gait variables measured during normal walking turn and straight walking phases as predictors of incident falls in a community-based sample of older adults (N = 253; mean age 78.5; 51% women). Cox regressions adjusted for multiple potential confounders were used to examine the associations. Results Participants had significantly slower stride velocity (57.81 vs 83.26 cm/s), shorter stride length (74.76 vs 101.81 cm,), lower swing (30.1 vs 32.41%), higher double support (39.79 vs 35.19%), and more swing (30.09 vs 32.41%) and stride length variability (31.86 vs 6.35 %) during turns compared with straights. Higher swing percent in both turns (adjusted hazard ratio; HR 0.92, 95% CI 0.87, 0.97) and straights (HR 0.89, 95% CI 0.84, 0.96) was associated with reduced risk of falls. Higher double support percent during both turns (HR 1.04, 95% CI 1.01, 1.07) and straights (HR 1.06, 95% CI 1.02, 1.09) was associated with increased risk of falls. More swing variability during turns (HR 1.03, 95% CI 1.00, 1.06), but not straights, was associated with increased risk of falls. Significance Gait variables collected during turning and walking straight were similar in their predictions of future falls. In the future, clinical research that builds on these findings could improve identification and prevention of falls.Objectives Ocrelizumab (OCR) is a humanized monoclonal antibody targeting CD20 antigen exposed on B cells surface. Kinetic of B-cells repopulation after depletion therapy shows high intra and inter-individual variability. The aim of this study was to explore the influence of Body Mass Index (BMI) on kinetic of B-cell repopulation after treatment with OCR and on treatment response. Methods 108 Multiple Sclerosis (MS) patients were enrolled at the time of the first dose of OCR administration and prospectively evaluated. Clinical, instrumental activity and disability progression were analyzed. According to B cells count, patients were divided into two groups with fast (FR) and with slow (SR) repopulation rate, respectively. Results Significant reduction of disease activity was observed in all patients and a stabilization of disease was obtained in progressive patients. Patients with FR had higher BMI compared to patients with a SR (p less then 0.001). Contrariwise no correlation between repopulation rate and treatment effectiveness was disclosed.
