Collagen is the main structural protein in vertebrates. It plays an essential role in providing a scaffold for cellular support and thereby affecting cell attachment, migration, proliferation, differentiation, and survival. Natural animal collagen and its recombinant collagen are favorable replacements in human tissue engineering due to their remarkable biomedical property. However, this ...
Diabetes, specifically Type 1 and Type 2 Diabetes Mellitus, remains one of the most commonly encountered metabolic diseases worldwide. The complexity and diversity of these conditions necessitate the development of detailed medical models for a comprehensive understanding of the diseases. Over time, Type 1 and Type 2 Diabetes Mellitus Models, Metabolic Disease Models, and generalized Diabetes ...
The field of medical science has long utilized disease models, which are systems simulating the progression and expression of a disease, to better understand various illnesses. These models facilitate the study of disease pathology, identifying underlying mechanisms, and developing potential treatments. In the context of respiratory diseases, numerous models have been developed, with a prominent ...
Classes of Cell-Penetrating Peptides There are many types of cell-penetrating peptides (CPPs), and their classification is based on physicochemical properties, sources, intake mechanisms, and biomedical applications. There is no unified conclusion yet. According to their physical and chemical properties, CPPs can be divided into three types: cationic, amphiphilic and hydrophobic, among which ...

The FDA's Center for Drug Evaluation and Research (CDER) regulatory approval of a total of 26 NME (New Molecular Entity) drugs in the first half of 2023. It is worth noting that the 26 drugs approved include 4 peptide drugs, accounting for 15% of the total. In the past 2022, the FDA has approved only three peptide drugs: Tirzepatide, Lutetium 177Lu Vipivotide Tetraxetan and Terlipressin, of which ...
Low Endotoxin Cytokines Matters Organoid culture, CAR-T cell therapy, stem cell therapy, and other topics have become broadly discussed among biomedical researchers. In fact, it is not difficult to see that these advanced technologies are all related to cell culture. In order to maintain efficient growth, proliferation, and differentiation during in vitro cell culture, many cell cultures require ...
What is RNA-Seq? Regulation of gene expression is fundamental to linking genotypes with phenotypes. RNAs shape complex gene expression networks, which drive biological processes. An in-depth understanding of the underlying mechanisms of how to govern these complex gene expression networks is vital for the treatment of complex diseases such as cancer. Hybridization-based microarrays are used to ...
Cell-penetrating peptides (CPPs) are short peptides that facilitate cellular intake and uptake of molecules ranging from nano-size particles to small chemical compounds to large fragments of DNA. As a versatile peptide, CPP has been widely used for diagnostic and therapeutic applications. 1. Oligo and siRNA Transport As an important means for targeted therapy of specific genes, oligonucleotides ...
CRISPR/Cas9 gene editing technology has been widely used in many fields since its inception. Gene therapy developed using this technology has huge prospects in the medical and health fields. CRISPR/Cas9 technology enables gene-editing of the genome at specified sites, but a common worry about the technology is that gene-editing occurs where it shouldn't. In recent years, researchers at the ...
Genetic mutations in cells are an important cause of cancer development, progression, and drug resistance. How to quickly and accurately translate massive tumor genomic information into safe and effective cancer targeted therapies in clinical practice is a scientific frontier today. At present, a large number of scientific studies have focused on how oncogenic mutations regulate the activity of ...
Gene editing technology, represented by CRISPR/Cas9, has greatly accelerated the development of gene therapy, bringing hope to many genetic diseases that otherwise had no cure. In June 2021, Intellia Therapeutics' NTLA-2001, a CRISPR gene editing therapy for the treatment of transthyretin amyloidosis (ATTR) invented by Nobel Laureate Jennifer Doudna, was proven to be safe and effective in a ...
Novel cytotoxic drugs New cytotoxic drugs have been developed to target cancer cells with low antigen expression or resistance to auristatins or maytansinoids. For this purpose, PBD dimers have been developed, which have a molecular structure containing two alkylated imine functional groups capable of forming covalent bonds with DNA.PBD dimers are about 50-100 times more potent than conventional ...
Simply put, CAR-T is to transform the patient's immune T cells in vitro by biotechnology, so that they recognize antigens on the surface of tumor cells, and then inject these cells back into the patient to achieve the therapeutic effect of recognizing and killing cancer cells. In 2017, CAR-T therapy was first approved by the FDA for the treatment of blood cancers such as leukemia and lymphoma. ...
