Define the terms homozygous and heterozygous. What makes a gene dominant, co-dominant or recessive? What is a recessive allele? Describe how selection for a dominant and a recessive allele will differ from one another. Explain how to determine if a mutation is dominant or recessive. Define alle...
Why are genes so important in terms of cell diversity? What is the best definition of a gene? Define gene. What are the definition of gene and gene expression? Explain why it is important to know how genes are regulated. Why is it important for a cell to be able to turn off a gene...
and 100 healthy controls) and a multi-omics cohort (63 RCC, 79 LCC, and 88 healthy controls) were analyzed. 16S rRNA gene, metagenomic sequencing, and metabolomics analyses of fecal samples were evaluated to identify tumor location-related bacteria and metabolites. Whole-exome sequencing (WES) ...
Intestinal stromal cells are known to modulate the propagation and differentiation of intestinal stem cells1,2. However, the precise cellular and molecular mechanisms by which this diverse stromal cell population maintains tissue homeostasis and repair are poorly understood. Here we describe a subset of...
Breast cancer (BC) is defined by distinct molecular subtypes with different cells of origin. The transcriptional networks that characterize the subtype-specific tumor-normal lineages are not established. In this work, we applied bulk, single-cell and sin
These cells have a large in-frame deletion that removes 67% of the coding sequence of the Wiz gene (including zinc fingers 2–5), likely resulting in a null allele. Western blot analysis confirmed that an epitope within the deleted region is not detected in Wizdel cells. Wizdel cells may...
2. “the essential error consists in the drawing of categorical conclusions from dimensional analyses.” and, “inconsistencies in characterizing the phenotype should be noted. mehta et al repeatedly equivocated on the terms posttraumatic stress disorder, ptsdsymptoms, and probableptsd. in fact, the ...
Moreover, specific RET haplotypes have been found to have either protective or predisposing effects, or to modulate the severity of the resulting phenotype.6–12 In particular, specific haplotypes comprising the rarer allele of a single nucleotide polymorphism (SNP) of exon 2 (A45A) have been ...
10 Various stress signals stabilise and activate p53, which exerts a tumour-suppressive function.9,11 Mutations in the p53 gene are found in 50% of human tumours,12 highlighting the importance of p53 in tumour suppression. Many p53 target genes that regulate various processes involved in the ...
Large-scale molecular profiling studies in recent years have shown that central nervous system (CNS) tumors display a much greater heterogeneity in terms of molecularly distinct entities, cellular origins and genetic drivers than anticipated from histological assessment. DNA methylation profiling has emerged...
