Double-stranded cDNA was constructed for poly(A)-containing RNA isolated from foetal human articular cartilage known to contain small amounts of pro alpha 1 (II) collagen mRNA. A 585 base pair PstI-EcoRI cDNA fragment was isolated and cloned into plasmid pBR322. A resulting recombinant plasmid pHCAR1 was shown to hybridize specifically to a 5.4 kilobase mRNA in cartilage but not in calvarial RNA. Definite identification of clone pHCAR1 was based on sequence analysis; marked homology with the corresponding chick gene and complete agreement with the human gene sequences available were observed.

The dissemination of tumor cells with ensuing metastasis is responsible for most cancer-related deaths. Cancer vaccines may, by inducing tumor-specific effector T cells, offer a strategy to eliminate metastasizing tumor cells. However, several obstacles remain in the development of effective cancer vaccines, including the identification of adjuvants that enhance the evolvement and efficacy of tumor-specific T cells.

Background: Antenatal depression (AND), occurring during pregnancy, is associated with severe outcomes. However, there is a lack of objective and universally applicable prediction methods for AND in clinical practice. We leveraged sociodemographic and pregnancy-related data to develop and validate a machine learning-based AND prediction model.

Background Aims: Hepatitis B virus (HBV) leads to severe liver diseases, such as cirrhosis and hepatocellular carcinoma. Identification of host factors that regulate HBV replication can provide new therapeutic targets. The discovery of sodium taurocholate cotransporting polypeptide (NTCP) as an HBV entry receptor has enabled the establishment of hepatic cell lines for analyzing HBV infection and propagation.

Background: Pancreatic ductal adenocarcinoma (PDAC) has a heterogeneous make-up of myeloid cells that influences the therapeutic response and prognosis. However, understanding the myeloid cell at both a genetic and cellular level remains a significant challenge.
Methods: Single-cell RNA sequencing (scRNA-seq) data were downloaded from t the Tumor Immune Single-cell Hub and gene expression data were retrieved from The Cancer Genome Atlas (TCGA) database and the Gene Expression Omnibus (GEO) database.

A 3D DNA spatial chip (DSC) based on an icosahedral DNA origami framework is introduced to construct customized circular single-stranded DNA (c-ssDNA) for data storage. Within the confined space of the DSC, thirty addressable location sequences extending from the framework edges are available for designing circular paths and directing the assembly of a series of information oligonucleotides for efficient ligation. This strategy is verified by constructing c-ssDNAs from up to 15 fragments to encode two poems (800 and 860 nucleotides).
