Micro/nanopatterning on a 2D surface is apt for cutting-edge miniaturization technology, which directly or indirectly requires high-end expensive lithographic tools. The evaporative deposition at the receding contact-line of a polymer solution, termed as Dynamic Contact Line Lithography (DCLL), can be a potential inexpensive technique for template-less meso-patterning if the deposition patterns from DCLL can be predicted a priori.

A deposition map (morphological phase diagram) from the myriads of patterns is constructed in terms of contact-line velocity and the polymer concentration. Specifically, two combinations polystyrene (PS)/cyclohexane and poly (methyl methacrylate) (PMMA)/toluene are used to show the generic nature of the phase diagrams. The surface wettability of Si (water contact angle, CA ~15°) is tuned from CA ~35° to ~98° by patterning with DCLL.

Directed by the phase diagrams, fabrication of a complex rectangular cross-pattern of PS and PMMA micro-threads with a periodicity of ~65μm and ~50μm respectively on a Si surface is demonstrated to establish the robustness and potential of the DCLL and predictive phase diagram.

Zinc finger protein 746 (ZNF746), initially identified as a Parkin-interacting substrate (PARIS), acts as a transcriptional repressor of peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) in Parkinson's disease. As recent studies reported that PARIS is associated with cancer onset, we investigated whether PARIS is associated with HCC. We found an increase in insoluble parkin and PARIS accumulation in the liver of diethylnitrosamine (DEN)-injected mice, leading to the downregulation of PGC-1α and nuclear respiratory factor 1 (NRF1). Interestingly, the occurrence of DEN-induced tumors was significantly alleviated in the livers of DEN-injected PARIS knockout mice compared to DEN-injected wild-type mice, suggesting that PARIS is involved in DEN-induced hepatocellular tumorigenesis. Moreover, H2O2-treated Chang liver cells showed accumulation of PARIS and downregulation of PGC-1α and NRF1. Thus, these results suggest that PARIS upregulation by oncogenic stresses can promote cancer progression by suppressing the transcriptional level of PGC-1α, and the modulation of PARIS can be a promising therapeutic target for HCC.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has the characteristic accessory protein ORF8. Although clinical reports indicate that ORF8 variant strains (Δ382 and L84S variants) are less likely to cause severe illness, functional differences between wild-type and variant ORF8 are unknown. Furthermore, the physicochemical properties of the ORF8 protein have not been analyzed. In this study, the physicochemical properties of the wild-type ORF8 and its L84S variant were analyzed and compared. Using the tobacco BY-2 cell production system, which has been successfully used to produce the wild-type ORF8 protein with a single conformation, was used to successfully produce the ORF8 L84S variant protein at the same level as wild-type ORF8. The produced proteins were purified, and their temperature and pH dependencies were examined using nuclear magnetic resonance spectra. Our data suggested that the wild-type and L84S variant ORF8 structures are highly stable over a wide temperature range. Both proteins displayed an aggregated conformation at higher temperature that reverted when the temperature was decreased to room temperature. Moreover, ORF8 precipitated at acidic pH and this precipitation was reversed when the solution pH was shifted to neutral. Interestingly, the L84S variant exhibited greater solubility than wild-type ORF8 under acidic conditions. Thus, the finding indicated that conformational stability and reversibility of ORF8 are key properties related to function in oppressive environments.In Arabidopsis, ERECTA (ER) subfamily of leucine-rich repeat (LRR) receptor kinases (LRR-RKs) play important roles in cell division and cell elongation. However, the functions of OsER genes in rice are still very much unknown. In this study, sixty-seven TILLING and four gene-edited mutants were identified for one of the three OsERs, OsERL, and used for functional analyses. Results showed that mutations in OsERL led to striking defects in anther development. Compete male sterility and reduced numbers of anther lobes, more severe than knockout mutants, were observed in mutants with amino acid substitutions in the kinase domain. HDAC activation Among alleles with amino acid changes in LRRs, only one mutation in the 16th LRR showed evident phenotype, suggesting a role of the LRR in ligand sensing. OsERL is expressed in shoot apcies, internodes and anthers, and within the anther OsERL is expressed in sporophytic and tapetal cells. Cell biological analyses revealed that mutations in OsERL led to defected periclinal division in archesporial cells in anthers, suggesting a critical role of OsERL in rice anther development.Junctophilin-2 (JPH2) was conventionally considered as a structural membrane binding protein. Recently, it was shown that proteolytically truncated mouse JPH2 variants are imported into nucleus to exert alternative functions. However, the intranuclear behaviors of human JPH2 (hJPH2) and underlying molecular determinants have not been explored. Here, we demonstrate that full-length hJPH2 is imported into nucleus in human cells by two nuclear localization signals (NLSs), including a newly discovered one at the C-terminus. Importantly, unlike the JPH2 N-terminal truncation which diffuses throughout the nucleus, full-length hJPH2 forms nuclear bodies behaving like liquid-liquid phase separated droplets that are separated from chromatin. The C-terminal transmembrane domain is required for the formation of hJPH2 droplets. Oxidation mimicking substitution of residues C678 and M679 augments the formation of hJPH2 nuclear droplets, suggesting nuclear hJPH2 liquid-liquid phase separation could be modulated by oxidative stress.
