The main function and biological processes of tissues are determined by the combination of gene expression and spatial organization of their cells. RNA sequencing technologies have primarily interrogated gene expression without preserving the native spatial context of cells. However, the emergence of various spatially-resolved transcriptome analysis methods now makes it possible to map the gene expression to specific coordinates within tissues, enabling transcriptional heterogeneity between different regions, and for the localization of specific transcripts and novel spatial markers to be revealed. Hence, spatially-resolved transcriptome analysis technologies have broad utility in research into human disease and developmental biology. Here, recent advances in spatially-resolved transcriptome analysis methods are summarized, including experimental technologies and computational methods. Strengths, challenges, and potential applications of those methods are highlighted, and perspectives in this field are provided.

The effect of hot air treatment on volatile compounds in nectarine fruit and the regulation of glycosidically bound compounds by sugar.

In order to investigate the impact of hot air (HA) treatment on the sugars and volatiles in postharvest nectarine fruit, nectarines were treated with HA at 40 °C for 4 h and stored at 1 °C for 35 days. Changes of sugars, free and glycosidically bound volatiles, β-glucosidase (β-Glu) activity, and the gene expression of UGT (UDP-glucosyltransferase) in nectarine fruit were determined. The results showed that compared with CK, HA treatment delayed the firmness decline of 48.

Objectives: This study aimed to assess mutagenicity biomarkers among Egyptian textile dyeing workers, their alteration with gene polymorphism, and the changes in plasma proteins' expression.
Methods: Using a detailed questionnaire, a comparative cross-sectional study was conducted on 212 workers (106 textile dyeing exposed group and 106 control group). CBMN-Cyt assay, ERCC2 gene polymorphism, and plasma protein fractions were analyzed in workers' blood samples.

People living with HIV (PLWH) experience HIV-associated neurocognitive disorders (HAND), even though combination antiretroviral therapy (cART) suppresses HIV replication. HIV-1 transactivator of transcription (HIV-1 Tat) contributes to the development of HAND through neuroinflammatory and neurotoxic mechanisms. C-C chemokine 5 receptor (CCR5) is important in immune cell targeting and is a co-receptor for HIV viral entry into CD4+ cells.

Surfactant protein-B (SP-B) deficiency is a lethal neonatal respiratory disease with few therapeutic options. Gene therapy using adeno-associated viruses (AAV) to deliver human cDNA (AAV-hSPB) can improve survival in a mouse model of SP-B deficiency. However, the effect of this gene therapy wanes.

In soils, the first rain after a prolonged dry period represents a major pulse event impacting soil microbial community function, yet we lack a full understanding of the genomic traits associated with the microbial response to rewetting. Genomic traits such as codon usage bias and genome size have been linked to bacterial growth in soils-however, often through measurements in culture. Here, we used metagenome-assembled genomes (MAGs) with O-water stable isotope probing and metatranscriptomics to track genomic traits associated with growth and transcription of soil microorganisms over one week following rewetting of a grassland soil.
