Human papillomaviruses (HPV) interact with cellular DNA damage repair (DDR) pathways to facilitate their propagation. According to research from the Fred Hutchinson Cancer Research Center, these interactions can be divided into two broad categories. The first category involves HPV proteins that activate DDR pathways, such as ATM and ATR, to

Zinc homeostasis is critical for maintaining cellular health, and recent research has shed light on the importance of zinc transport proteins in achieving this balance. A study published in the International Journal of Biochemistry & Cell Biology has identified three novel zinc dyshomeostasis phenotypes in the vinegar fly Drosophila melanogaster,
Biochemistry
Cyclin A1, an A-type cyclin, plays a crucial role in regulating cell-cycle progression by binding directly to CDK2. Research conducted at the Korea Institute of Radiological and Medical Sciences has shed light on the mechanisms by which doxorubicin, a DNA-damaging agent, downregulates cyclin A1 in A549 lung cancer cells. The

Researchers have made a significant contribution to the understanding of DNA methylation and its impact on cardiovascular diseases. A study conducted as part of the Atherosclerosis Risk in Communities (ARIC) study has provided insight into the reliability of DNA methylation measurement using the Illumina Infinium HumanMethylation450 (HM450) BeadChip. The study
Biochemistry
Research conducted by W. Xiao and colleagues at the University of Iowa has demonstrated that selenoprotein P (SEPP1) plays a crucial role in regulating oxidative stress and toxicity induced by polychlorinated biphenyls (PCBs) in human keratinocytes. The study, published in Free Radical Biology & Medicine, found that SEPP1 downregulation was
Biochemistry
Researchers from the Autonomous University in Bellaterra, Spain have developed a novel fiber optic measurement system to determine the stability of pork emulsions using light backscatter. The study aimed to investigate whether the intensity of light backscatter within the 300-1100 nm wavelength range could be correlated with final product stability
Biochemistry
Researchers in Japan have made new findings in the process of carcinogenesis, a key driver of cancer development. By analyzing mouse skin cancer tissues induced by a 2-stage carcinogenesis model, the team identified differentially methylated regions (DMRs) that are associated with gene expression regulation during carcinogenesis. These findings have significant
Biochemistry
Research conducted by scientists at Yale University has shed light on the mechanism of action of volatile organic compounds (VOCs) produced by the fungus Muscodor albus, which has been found to inhibit and kill other fungi, bacteria, and insects. The study, published in Applied and Environmental Microbiology, used genetic screens
Proteins
Research has shown that ExsA, a member of the AraC family of transcriptional regulators, plays a critical role in activating the type III secretion system (T3SS) in Pseudomonas aeruginosa. This process involves the binding of ExsA to specific DNA sequences, a mechanism that is conserved across different bacterial species. However,

Researchers from Vanderbilt University have successfully designed and crystallized a small molecule inhibitor of the Replication Protein A (RPA) interaction motif, a critical component of the DNA damage response and repair pathway. This innovation holds promise for the development of cancer treatments that target the upregulation of DNA damage response
Universities and colleges
Researchers from Duke University have developed a novel method, surface-initiated enzymatic polymerization (SIEP), for detecting DNA hybridization on a chip. This approach utilizes terminal deoxynucleotidyl transferase (TdT) to incorporate multiple fluorophores into a single-stranded DNA (ssDNA) chain, enabling efficient detection of DNA hybridization. The researchers demonstrated the sensitivity of this
