Vector construction and gene cloning are ubiquitous techniques essential to all fields of biological and medical research. They are the first steps in many endeavors leading to expressing proteins to understand gene function and regulation. However, they can often be rate-limiting, particularly in multi-gene studies, due to the time and effort required to assemble gene constructs and to identify the optimal constructs for protein expression.The SureVector system was developed to address this by enabling the rapid and reliable assembly of multiple DNA modules into a recombinant plasmid containing a gene-of-interest (GOI). It harnesses the power of synthetic biology to combine DNA modules from standard parts into a customized vector that expresses proteins in bacterial, mammalian, or yeast cells. The key advantages of the innovative SureVector system include rapid custom vector generation, enhanced flexibility to assemble new vectors quickly as experimental requirements change, and the reliable and precise assembly of fully interchangeable standard DNA modules that retain their functionality. The SureVector system is the only next-generation plasmid assembly technology to guarantee assembly of multiple functional DNA modules.

Numerous regulators of cardiomyocyte (CM) proliferation have been identified, yet how they coordinate during cardiac development or regeneration is poorly understood. Here, we developed a computational model of the CM proliferation regulatory network to obtain key regulators and systems-level understanding. The model defines five modules (DNA replication, mitosis, cytokinesis, growth factor, Hippo pathway) and integrates them into a network of 72 nodes and 88 reactions that correctly predicts 73 of 78 (93.

Phytochromes are biliprotein photoreceptors found in bacteria, fungi, and plants. The soil bacterium Agrobacterium fabrum has two phytochromes, Agp1 and Agp2, which work together to control DNA transfer to plants and bacterial conjugation. Both phytochromes interact as homodimeric proteins.

Light serves as an energy source for cell division and expansion during fruit development. Cell expansion significantly influences fruit size and is closely linked to endoreduplication, a unique cell cycle variation characterized by DNA replication without cytokinesis. Paradoxically, under conditions of ample photosynthates, light signaling suppresses cell expansion.

It is known that red light irradiation enhances the biosynthesis of (E)-β-caryophyllene in plants. However, the underlying mechanism connecting red light to (E)-β-caryophyllene biosynthesis remains elusive. This study reveals a molecular cascade involving the phyB-PIF4-MYC2 module, which regulates (E)-β-caryophyllene biosynthesis in response to the red light signal in Arabidopsis thaliana.

The bromodomain (BRD) represents a highly conserved structural module that provides BRD proteins with fundamental functionality in modulating protein-protein interactions involved in diverse biological processes such as chromatin-mediated gene transcription, DNA recombination, replication and repair. Consequently, dysregulation of BRD proteins has been implicated in the pathogenesis of numerous human diseases. In recent years, considerable scientific endeavors have focused on unraveling the molecular mechanisms underlying BRDs and developing inhibitors that target these domains.
