Identification of DNA-binding protein target sequences by physical effective energy functions. Free energy analysis of lambda repressor-DNA complexes [PDF]
BMC Structural Biology 2007, 7:61, 2007 Specific binding of proteins to DNA is one of the most common ways in which gene expression is controlled. Although general rules for the DNA-protein recognition can be derived, the ambiguous and complex nature of this mechanism precludes a simple recognition code, therefore the prediction of DNA target sequences is not straightforward.

Clerocidin selectively modifies the gyrase-DNA gate to induce irreversible and reversible DNA damage [PDF]
, 2008 Clerocidin (CL), a microbial diterpenoid, reacts with DNA via its epoxide group and stimulates DNA cleavage by type II DNA topoisomerases. The molecular basis of CL action is poorly understood.

Preparation of fluorescent DNA probe by solid-phase organic synthesis
eXPRESS Polymer Letters, 2009 Fluorescent DNA probe based on fluorescence resonance energy transfer (FRET) was prepared by solid-phase organic synthesis when CdTe quantum dots (QDs) were as energy donors and Au nanoparticles (AuNPs) were as energy accepters.

Population Ecology, Volume 67, Issue 2, Page 125-139, April 2025.In this article, we tested optimal SNP filtering strategies for accurate parentage assignment and pedigree reconstruction for a wild population of red‐spotted masu salmon, Oncorhynchus masou ishikawae. We found that mid‐point filtering in terms of call rate and minor allele frequency performs well for pedigree reconstruction.

Method of identifying inhibitors of glutathione S-transferase (GST) gene expression [PDF]
, 1999 Complementary DNA and genomic clones for three variants of GST-.pi. are disclosed. It is demonstrated that certain of these variants are overexpressed in gliomas, thereby indicating an involvement with that form of cancer.

Evaluating the origin and spread of spotted lanternfly (Lycorma delicatula) in Japan
Population Ecology, Volume 67, Issue 2, Page 162-179, April 2025.The invasive spotted lanternfly (Lycorma delicatula) is native to China and is a serious economic pest in the Republic of Korea and the United States, though it is not considered a pest in Japan. We established a distribution map of L. delicatula in Japan through a comprehensive review of published literature and citizen science reports and analyzed ...
