Flexibility-Rigidity Index for Protein-Nucleic Acid Flexibility and Fluctuation Analysis [PDF]
arXiv, 2015 Protein-nucleic acid complexes are important for many cellular processes including the most essential function such as transcription and translation. For many protein-nucleic acid complexes, flexibility of both macromolecules has been shown to be critical for specificity and/or function. Flexibility-rigidity index (FRI) has been proposed as an accurate

Ubiquitination of transcription factors in cancer: unveiling therapeutic potential
Molecular Oncology, EarlyView.In cancer, dysregulated ubiquitination of transcription factors contributes to the uncontrolled growth and survival characteristics of tumors. Tumor suppressors are degraded by aberrant ubiquitination, or oncogenic transcription factors gain stability through ubiquitination, thereby promoting tumorigenesis.

Molecular Therapy: Oncolytics, 2021 Resistance to the BCR-ABL inhibitor imatinib mesylate poses a major problem for the treatment of chronic myeloid leukemia. Imatinib resistance often results from a secondary mutation in BCR-ABL that interferes with drug binding.

Red blood cells could protect miRNAs from degradation or loss thanks to Argonaute 2 binding
FEBS Open Bio, EarlyView.The present work investigates the presence and the stability of miRNAs into RBCs, both native and engineered. The observed stability is due to the Ago2 bound resulting in minimal RISC. Indeed, if the miRNA‐Ago2 complex is present, miRNAs are protected from release or degradation and they are biologically active. Thus, RBCs can act as miRNA carriers for

DNA Renaturation at the Water-Phenol Interface [PDF]
, 2003 We study DNA adsorption and renaturation in a water-phenol two-phase system, with or without shaking. In very dilute solutions, single-stranded DNA is adsorbed at the interface in a salt-dependent manner. At high salt concentrations the adsorption is irreversible.

Establishment and biological characterization of radioresistant colorectal cancer cell lines
FEBS Open Bio, EarlyView.Under ionizing radiation exposure, radiation‐sensitive cancer cells exhibit oxidative stress and DNA damage, while radiation‐resistant cancer cells exhibit strong antioxidant properties and DNA damage repair. Radiotherapy resistance is a major cause of recurrence and metastasis in colorectal cancer (CRC).

Possible role of human ribonuclease dicer in the regulation of R loops
FEBS Open Bio, EarlyView.R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Controlled enzymatic synthesis of oligonucleotides
Communications ChemistryOligonucleotides are advancing as essential materials for the development of new therapeutics, artificial genes, or in storage of information applications. Hitherto, our capacity to write (i.e., synthesize) oligonucleotides is not as efficient as that to
