Rational design of polyarginine nanocapsules intended to help peptides overcoming intestinal barriers

Overcoming mutation-based resistance to antiandrogens with rational drug design

The second-generation antiandrogen enzalutamide was recently approved for patients with castration-resistant prostate cancer. Despite its success, the duration of response is often limited. For previous antiandrogens, one mechanism of resistance is mutation of the androgen receptor (AR). To prospectively identify AR mutations that might confer resistance to enzalutamide, we performed a reporter...

Prediction and Rational Design of Antimicrobial Peptides

Overcoming Barriers to Evaluation of Terminological Systems

Evaluation of terminological systems has been demonstrated to be a complicated task. This is due to the broad range of terminological systems, their application, and the clinical contexts in which they can be applied. We propose an evaluation framework that explicitly distinguishes an application-independent description of terminological systems, methods to determine application-dependent requi...

Lumican Peptides: Rational Design Targeting ALK5/TGFBRI

Lumican, a small leucine rich proteoglycan (SLRP), is a component of extracellular matrix which also functions as a matrikine regulating multiple cell activities. In the cornea, lumican maintains corneal transparency by regulating collagen fibrillogenesis, promoting corneal epithelial wound healing, regulating gene expression and maintaining corneal homeostasis. We have recently shown that a pe...

Hybridization properties of oligodeoxynucleotide pairs bridged by polyarginine peptides.

The hybridization properties of a series of probes, based on two 9mer oligodeoxynucleotides (designated as I and II) having an appended oligoarginine chain (Rn) to produce peptide-oligonucleotide conjugates or peptide-bridged oligonucleotide pairs (e.g. Rn-I or II-Rn-I), were investigated. For the double-linked probes, we found that the peptide bridge induces the two 9mers to bind complementary...
