6e). To analyze these data, we first constructed RNA-seq and ATAC-seq references composed of normal epithelial colon cells collected from patients without FAP (Fig. 3a). We annotated cell types in this normal tissue using gene expression and gene activity scores of known marker genes (Extended...
3.A virion is composed of either DNA or RNA enclosed in a coat of protein (and sometimes other substances as well). It cannot reproduce independently of living cells. 4. Viruses are cultivated using tissue cultures, embryonated eggs, bacterial cultures, and other living hosts. 5. Sites of...
Glucose starvation induces the accumulation of disulfides and F-actin collapse in cells with high expression of SLC7A11, a phenomenon termed disulfidptosis. This study aimed to confirm the existence of disulfidptosis in pancreatic ductal adenocarcinoma (
Improving the egg production of goose is a crucial goal of breeding, because genetics is the key factor affecting egg production. Thus, we sequenced the genomes of 55 Chinese indigenous geese from six breeds, which were divided into the high egg-laying g
genomes6,7,8. In contrast to otherPlasmodiumgenomes, putative variant antigen families are dispersed throughout the genome and are associated with intrachromosomal telomere repeats. One of these families, the KIRs9, contains sequences that collectively match over one-half of the host CD99 ...
There were two distinct clusters, one was predominantly composed of samples with MAGs annotated to strain NCTC9343, and the other was dominated by samples with MAGs annotated to strain Q1F2. Consequently, we manually divided the 334 StrainPhlAn3 samples into two clusters. Cluster 1 (related to...

HGT leads to the rapid spread of new genes and allows the build-up of larger, fitter genomes than could be achieved by purely vertical inheritance. In contrast, if the gene loss rate is lower, as in modern prokaryotes, then HGT is, on average, unfavourable. Conclusions Modern cells should...

These observations suggest that the differentiation of stone cells, which are types of sclerenchyma cells, must begin with the formation of a framework of secondary walls that are primarily composed of cellulose and hemicellulose. Cellulose is the most abundant component of secondary cell walls. We ...
