The ability to overexpress genes in microorganisms has revolutionized the field of synthetic biology. Gene overexpression involves the production of large quantities of target proteins by increasing the transcription and translation of the gene of interest. This technique has been applied in the engineering of microorganisms to produce a wide range of products, including biofuels, chemicals, and biopharmaceuticals. There are several strategies for gene overexpression in strain engineering. One c...

In the field of scientific research, understanding and studying emotion-related behaviors in animals plays a crucial role in advancing the knowledge of the human brain and mental health. Animal models can help researchers better comprehend animal behaviors, and rodent models in particular have become important objects for understanding the mechanisms of emotional behaviors and exploring new treatments for emotion-related disorders including anxiety, depression, and stress. With their remarkable ...

The diagnosis and treatment of rare diseases have long been a daunting challenge due to their complex and often undefined nature. However, with recent advancements in technology, specifically in the realm of genomics, whole genome sequencing (WGS) has emerged as a powerful tool that has revolutionized the diagnosis and management of rare diseases. This groundbreaking technique offers hope to countless individuals and their families who have suffered from the uncertainties and lack of answers ass...

What is cystic fibrosis?Cystic fibrosis (CF) is a rare genetic disorder that affects the lungs, digestive system, and other organs. It is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which encodes a protein that regulates chloride ions transport across cell membranes. These mutations cause the CFTR protein to be either absent or not function properly, leading to the buildup of thick, sticky mucus in the lungs, pancreas, and other organs. Treatment o...

The importance of nucleic acids in controlling life processes is well known. Under the suitable conditions, DNA molecules are responsible for replication of themselves and acts as templates for RNA synthesis in transcription. In translation, RNA molecules control protein synthesis and thus various metabolic activities in living cells. All these processes are monitored by sequences of bases in polynucleotide chains. Nucleosides consist of a sugar group and a heterocyclic nucleobase that bound to ...

Bioink is a solution of a biomaterial or a mixture of several biomaterials in the hydrogel form, usually encapsulating living cells, and/or bioactive molecules. For bioprinting, bioinks are essential components, and are cross-linked or stabilized during or immediately after the bioprinting to create the final shapes of the intended tissue constructs.The selection of appropriate bioink depends on the specific application and the type of cells as well as the bioprinter to be used. An ideal bioink ...

Laboratory equipment is a general term for the various instruments, containers and other tools needed for operation, synthesis, and analysis in various laboratories. The equipment helps researchers to observe, test, experiment or analyze data to confirm the authenticity or rationality of scientific hypotheses. According to the scope of application, laboratory equipment can be divided into general equipment and specialized equipment.General laboratory equipment includes freezers, incubators, shak...

ethylation-Based Biological Age and Cancer RiskChanges in DNA methylation levels with age, and it has been widely studied as a well-known biomarker of aging. A number of DNA methylation age clocks have appeared and been used, and when the age predicted by the methylation clock is greater than the actual age, it is considered to have "age acceleration", which is also called the biological measure of aging.Research suggests a correlation between aging and cancer as well. Predicted ages obtained by...

The aging of today's global population is accelerating, leading to a higher incidence of some diseases related to aging, such as chronic diseases, neurodegenerative diseases, cardiovascular diseases, etc. However, people at the same age may show different disease expressions, and one possible factor is due to differences in the aging process of different individuals, which means that the actual age of individuals is the same but their biological age may be different.Then understanding the biolog...
