The disclosure discloses recombinant Bacillus subtilis for synthesizing guanosine diphosphate fucose and a construction method and application thereof. The recombinant Bacillus subtilis is obtained by intensively expressing guanylate kinase and nucleotide diphosphokinase genes and expressing exogenous fucokinase and phosphate guanylyltransferase genes in a genome of Bacillus subtilis 168. According to the disclosure, a bacterial strain for synthesizing the guanosine diphosphate fucose is obtained by reconstructing the Bacillus subtilis 168, with a volume of intracellular accumulation up to 196.15 g/L. According to the disclosure, by intensively expressing the guanylate kinase and nucleotide diphosphokinase genes, and enhancing the supply of intracellular GDP-L-fucose composition cofactors, the synthesis of the guanosine diphosphate fucose is promoted. The construction method for the recombinant Bacillus subtilis of the disclosure is simple and convenient to use, thus having good application prospects.

The present invention is related to a method to be performed with one tissue type, wherein a specific combination of hydrogel features has been pre-selected for the said one tissue type to be tested. The present invention is also related to a kit of parts to perform said method.

Described herein are genetically modified cells derived from a human cell and which contain at least one exogenous transcription unit inserted into at least one of four open chromatin regions (OCRs) located on Chromosomes 2, 5, 8 and 12, as well as compositions, pharmaceutical preparations, and implantable devices comprising the genetically modified cells, and methods of using the same for preventing or treating a disease, disorder, or condition.

The present disclosure relates to a well plate for 3D cell spheroid culture that facilitates 3D cell spheroid culture and enables cell adhesion and detachment by adjusting a surface roughness, a method for manufacturing the well plate for 3D cell spheroid culture, and a method for 3D cell spheroid culture using the same.

A method for producing an objective protein by using animal cells as an expression host is provided. The objective protein is produced by culturing animal cells having an objective protein-producing ability in the presence of an L-cysteine derivative such as (2RS,4R)-2-methyl-2,4-thiazolidinedicarboxylic acid 2-ethyl ester.

A lung breathing chip and cell stretching culture platform and an operating method thereof are disclosed. The lung breathing chip and cell stretching culture platform controls the output of the motor by programming, stretches the micro-fluidic chip by the cam component, changes the size of the cam component and the frequency of the motor rotation to change the stretching frequency and the amount of stretching to simulate the breathing of the lungs in different states, uses liquid electrophoresis technology to arrange the cells in the biocompatible hydrogel and the hydrogel three-dimensionally to imitate the three-dimensional cell tissue, and injects drugs through the dynamic perfusion system to realize the drug testing platform that the cells of the chip bionic lung tissue are stretched.

The present disclosure relates generally to therapeutic agents that may be useful as modulators of Integrated Stress Response (ISR) pathway.
