Molecular theory of hydrophobic mismatch between lipids and peptides

open access: yes, 2001
Effects of the mismatch between the hydrophobic length, d, of transmembrane alpha helices of integral proteins and the hydrophobic thickness, D_h, of the membranes they span are studied theoretically utilizing a microscopic model of lipids. In particular,

Structural and biophysical analysis of important biomedical enzymes and nano-architectures [PDF]

open access: yes, 2008
Dopa decarboxylase (DDC) is an important enzyme in the catecholamine biosynthesis pathways. Catecholamines, e.g., dopamine, serotonin, etc. often are the major neuromodulators or neurotransmitters.

Proteomics reveals the function reverse of MPSSS‐treated prostate cancer‐associated fibroblasts to suppress PC‐3 cell viability via the FoxO pathway

open access: yesCancer Medicine, 2021
Prostate cancer‐associated fibroblasts (prostate CAFs) are essential components of the tumor microenvironment and can promote tumor progression through their immunosuppressive functions.

HPEPDOCK: a web server for blind peptide–protein docking based on a hierarchical algorithm

open access: yesNucleic Acids Res., 2018
Protein–peptide interactions are crucial in many cellular functions. Therefore, determining the structure of protein–peptide complexes is important for understanding the molecular mechanism of related biological processes and developing peptide drugs ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

A peptide encoded by circular form of LINC-PINT suppresses oncogenic transcriptional elongation in glioblastoma

open access: yesNature Communications, 2018
Circular RNAs (circRNAs) are a large class of transcripts in the mammalian genome. Although the translation of circRNAs was reported, additional coding circRNAs and the functions of their translated products remain elusive.

A Cre‐dependent lentiviral vector for neuron subtype‐specific expression of large proteins

open access: yesFEBS Letters, EarlyView.
We designed a versatile and modular lentivector comprising a Cre‐dependent switch and self‐cleaving 2A peptide and tested it for co‐expression of GFP and a 2.8 kb gene of interest (GOI) in mouse cortical parvalbumin (PV+) interneurons and midbrain dopamine (TH+) neurons.

Alloreactive cytotoxic T lymphocytes generated in the presence of viral- derived peptides show exquisite peptide and MHC specificity [PDF]

open access: yes, 1993
The nature of alloreactivity to MHC molecules has been enigmatic, primarily because of the observation that allogeneic responses are considerably stronger than syngeneic responses. To better determine the specificity potential of allogeneic responses, we

Fibrillisation of hydrophobically modified amyloid peptide fragments in an organic solvent [PDF]

open access: yes, 2007
The self-assembly of a hydrophobically modified fragment of the amyloid beta(A beta) peptide has been studied in methanol. The peptide FFKLVFF is based on A beta(16-20) extended at the N terminus by two phenylalanine residues.

Feedback Inhibition of CREB Signaling Promotes Beta Cell Dysfunction in Insulin Resistance

open access: yesCell Reports, 2015
Although persistent elevations in circulating glucose concentrations promote compensatory increases in pancreatic islet mass, unremitting insulin resistance causes deterioration in beta cell function that leads to the progression to diabetes.
