STMGraph: spatial-context-aware of transcriptomes via a dual-remasked dynamic graph attention model.

Spatial transcriptomics (ST) technologies enable dissecting the tissue architecture in spatial context. To perceive the global contextual information of gene expression patterns in tissue, the spatial dependence of cells must be fully considered by integrating both local and non-local features by means of spatial-context-aware. However, the current ST integration algorithm ignores for ST dropouts, which impedes the spatial-aware of ST features, resulting in challenges in the accuracy and robustness of microenvironmental heterogeneity detecting, spatial domain clustering, and batch-effects correction.

Artesunate alleviates psoriasis-like dermatitis by reducing interleukin-23 expression in tumor necrosis factor-alpha-induced HaCaT cells.

Artesunate (ART), an antimalarial drug with a multifunctional immunomodulatory effect, reduces psoriasis disease. ART can alleviate psoriasis-like dermatitis in mice but has no effect on proinflammatory cytokines in the blood. Thus, we hypothesized that the skin might be the target tissue of ART during the treatment of psoriasis.

Pantranscriptome combined with phenotypic quantification reveals germplasm kinship and regulation network of bract color variation in .

Bracts are the metamorphic non-flower organ in angiosperm plants. The variation of the color and shape of bracts was found to be neo-functionalized (i.e.

Genome-wide identification and adaptive evolution of CesA/Csl superfamily among species with different life forms in Orchidaceae.

Orchidaceae, with more than 25,000 species, is one of the largest flowering plant families that can successfully colonize wide ecological niches, such as land, trees, or rocks, and its members are divided into epiphytic, terrestrial, and saprophytic types according to their life forms. Cellulose synthase () and cellulose synthase-like () genes are key regulators in the synthesis of plant cell wall polysaccharides, which play an important role in the adaptation of orchids to resist abiotic stresses, such as drought and cold. In this study, nine whole-genome sequenced orchid species with three types of life forms were selected; the CesA/Csl gene family was identified; the evolutionary roles and expression patterns of CesA/Csl genes adapted to different life forms and abiotic stresses were investigated.

New Insights into Artesunate as a Pleiotropic Regulator of Innate and Adaptive Immune Cells.

Artesunate, one of the derivatives of artemisinin ("qinghaosu" in Chinese), is known as an antimalarial drug with high efficiency and low toxicity. Of interest, emerging evidences suggest that artesunate also possesses an immunomodulatory effect during innate and adaptive immune responses in cell types and context-dependent manner. Although it shows promising application in many diseases, such as inflammatory diseases, hypersensitivity, autoimmune diseases, and cancers, little is known about underlying molecular.

Transcriptome comparison reveals candidate genes responsible for the betalain-/anthocyanidin-production in bougainvilleas.

The occurrence of betalains and anthocyanins is mutually exclusive, which is a curious phenomenon in the plant kingdom, and the biochemical mechanisms for this restriction are unknown. In the present study, we performed transcriptome analysis of two betalain-producing species, red Bougainvillea glabra Choisy. 'Sanderiana' (R) and white B.

A water-stable metal-organic framework of a zwitterionic carboxylate with dysprosium: a sensing platform for Ebolavirus RNA sequences.

We herein report a water-stable 3D dysprosium-based metal-organic framework (MOF) that can non-covalently interact with probe ss-DNA. The formed system can serve as an effective fluorescence sensing platform for the detection of complementary Ebolavirus RNA sequences with the detection limit of 160 pM.
