Disease relevant mutations can be recapitulated or even correct by introducing a point mutation with a single base change, or by inserting/deleting large gene sequences. These endogenous knock-in cell lines enable a clear understanding of the contribution of the gene or mutation to a phenotype. There are unlimited uses for point mutation cell lines at pre-defined loci, including functional ...
Protein fusion is a genetic recombination technique in which the DNA of an inactive peptide or protein chain segment to be grafted is recombined with the DNA of a drug and expressed together by engineered cells; no specialized grafting operations are required. In the current technology, the inactive peptide or protein chain segment used for protein fusion is the FC region of albumin and antibody. ...

Microspheres are small spherical entities formed by dispersing or adsorbing drugs in a polymer matrix. The particle size is typically between 1 μm and 250 μm, and the largest can reach more than 800 μm. Microsphere technology is at the intersection of cutting-edge disciplines such as materials science, polymer technology, medical technology, and microelectronics. Once injected into the ...
Gene editing is one of the latest breakthroughs in biology. The well-known CRISPR-Cas gene editing system confers immunity against foreign DNA to prokaryotes (organisms lacking a cell nucleus). Since the discovery of CRISPR gene editing technology, scientists have revealed how CRISPR-cas proteins evolved from their precursors. This knowledge will help them develop other small new genome editing ...
Currently, the incidence of infectious diseases has increased globally, and the pathogens show a trend of diversification and complexity. Rapid and accurate pathogenic diagnosis, which enables early selection of sensitive anti-infective drugs or effective and targeted preventive and control measures, is the core of accurate prevention and treatment of infectious diseases. The epidemic of ...
The cell is the basic unit of life. Most current studies on the human genome, cancer or other fields are still conducted from the population level, and the results are often the mean value of gene expression in cell populations or only represent information on the vital activities of numerically dominant cells, while failing to accurately reflect much of the information on cellular heterogeneity ...
IntroductionTumorigenesis involves in many somatic mutations, most of which are random. Generally, hundreds of genes are thought to be associated with oncogenesis progression and have high mutation rates. Digging deeper into the cancer genome can help to understand the molecular mechanisms of tumorigenesis and provide guidance for the prevention, treatment and prognosis strategies. The main ...
Advances in DNA sequencing technology have made it possible to extensively analyze the breast tumor genome and construct a catalog of gene mutations that may initiate or drive tumor progression. In addition to the well-known common mutations in oncogenes (such as TP53 and PIK3CA), breast cancer also contains a variety of rare mutations that have a low incidence in the patient population. Despite ...
