Microfluidic Generation of Amino-Functionalized Hydrogel Microbeads Capable of On-Bead Bioassay

open access: yesMicromachines, 2019
Microfluidic generation of hydrogel microbeads is a highly efficient and reproducible approach to create various functional hydrogel beads. Here, we report a method to prepare crosslinked amino-functionalized polyethylene glycol (PEG) microbeads using a ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Rapid microwave-assisted solid phase peptide synthesis

open access: yes, 2002
A microwave-assisted, rapid solid phase peptide synthesis procedure is presented. It has been applied to the coupling of sterically hindered Fmoc-protected amino acids yielding di- and tripeptides.

Synthetic receptors for the differentiation of phosphorylated peptides and synthesis and use of tetrahydrofuran amino acids [PDF]

open access: yes, 2010
In the first part of the work a combination of bis(Zn(II)-cyclen) triazine metal complex binding sites with guanidinium moieties or Zn(II)-NTA complexes leads to artificial receptors for the differentiation of phosphorylated peptides which contain either

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

open access: yesMolecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Deprotection Strategies for Thioimidates During Fmoc Solid-Phase Peptide Synthesis: A Safe Route to Thioamides [PDF]

open access: yes, 2019
Thioamides are important biophysical probes of peptide folding, but are prone to alpha-C epimerization during Fmoc solid-phase peptide synthesis. The stereochemical integrity of thioamide-containing peptides can be dramatically improved by protecting the

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

p190A/ARHGAP35 and p190B/ARHGAP5 proteins in endometrial cancer: a novel cancer‐relevant paralog interplay

open access: yesMolecular Oncology, EarlyView.
This study identifies ARHGAP5, in addition to the frequently mutated ARHGAP35, as significantly mutated in endometrial cancer. Mutations in both genes co‐occur and are associated with their correlated downregulation. Functional CRISPR studies show that both paralogs regulate similar pathways, including actin cytoskeleton organization.

Development of the optimal scheme for the synthesis of the dipeptide TSPO ligand, N-phenylpropionyl-L-tryptophanyl-L-leucine amide (GD-102), a potential anxiolytic drug

open access: yesФармакокинетика и Фармакодинамика
Previously at the Zakusov Research Institute of Pharmacology the first dipeptide ligand TSPO, the compound N-phenylpropionyl-L-tryptophanyl-L-leucine amide (laboratory code GD-102), was designed and synthesized.

Synthesis and characterization of PNA based molecules able to interfere with gene regulation [PDF]

open access: yes, 2011
The control of gene expression is a fundamental process to bring the genome to life, and it pervades most of biology, from cell proliferation and differentiation to development. Mis-regulation of gene expression at any level can lead to disease.MicroRNAs,
