We describe a protocol for the fluorescent electrophoretic mobility shift assay improved for the quantitative analysis of protein-DNA complexes. Fluorescent-labeled oligonucleotide probes incubated with nuclear proteins were followed by electrophoresis. The signals for protein-DNA complexes were measured and normalized with fluorescent-labeled marker using fragment analysis software. This assay proved reliable measurement and multiple detection of DNA binding proteins.

Background: Cancer immunotherapy has transformed metastatic cancer treatment, yet challenges persist regarding therapeutic efficacy. RECQL4, a RecQ-like helicase, plays a central role in DNA replication and repair as part of the DNA damage response, a pathway implicated in enhancing efficacy of immune checkpoint inhibitor (ICI) therapies. However, its role in patient response to ICI remains unclear.

The correct synthesis and degradation of proteins are vital for numerous biological processes in the human body, with protein degradation primarily facilitated by the ubiquitin-proteasome system. The SKP1-CUL1-F-box (SCF) E3 ubiquitin ligase, a member of the Cullin-RING E3 ubiquitin ligase (CRL) family, plays a crucial role in mediating protein ubiquitination and subsequent 26S proteasome degradation during normal cellular metabolism. Notably, SCF is intricately linked to the pathogenesis of various diseases, including malignant tumors.

SMARCA4-deficient lung cancer, including thoracic SMARCA4-deficient undifferentiated tumors and SMARCA4-deficient nonsmall-cell lung carcinomas, is a rare and aggressive disease characterized by rapid progression and poor prognosis. This cancer was identified as a distinct entity with specific morphologic and molecular features in the 2021 WHO Classification of Thoracic Tumors. Molecular alterations in SMARCA4 are specific to this type of lung cancer.

Analyzing the cell interface is of paramount importance in understanding how cells interact and communicate with other cells, but an advanced analytical platform that can process complex and networked interactions between cell surface ligands and receptors is lacking. Herein, we developed the cell-interface-deciphering lipid nanotablet (CID-LNT) for multiplexed real-time cell analysis. LNT is a nanoparticle-tethered lipid bilayer chip where freely diffusing plasmonic nanoparticles induce scattering signal changes.

Hemophilia A (HA) is an inherited condition that is characterized by a lack of coagulation factor VIII (FVIII), which is needed for blood clotting. To produce recombinant factor VIII (rFVIII) for treatment, innovative methods are required. This study presents a thorough examination of the genetic engineering and biotechnological methods that are essential for the production of this complex process.
