Interactions between $β$-endorphin and kisspeptin neurons of the ewe arcuate nucleus are modulated by photoperiod [PDF]

Journal of Neuroendocrinology, In press, 2023
Opioid peptides are well-known modulators of the central control of reproduction. Among them, dynorphin coexpressed in kisspeptin (KP) neurons of the arcuate nucleus (ARC) has been thoroughly studied for its autocrine effect on KP release through $\kappa$ opioid receptors.

AIF1+CSF1R+ MSCs, induced by TNF‐α, act to generate an inflammatory microenvironment and promote hepatocarcinogenesis

Hepatology, EarlyView., 2022
Mesenchymal stem cells subset, educated by TNF‐α, are involved to generate inflammatory microenvironment and promote hepatocarcinogenesis Abstract Background and Aims Increasing evidence suggests that mesenchymal stem cells (MSCs) home to injured local tissues and the tumor microenvironment in the liver.

c‐Rel–dependent Chk2 signaling regulates the DNA damage response limiting hepatocarcinogenesis

Hepatology, EarlyView., 2022
In response to genotoxic injury, c‐Rel upregulates ATM‐Chk2‐p53 pathway DNA damage proteins to limiting hepatocarcinogenesis. Abstract Background and Aims Hepatocellular carcinoma (HCC) is a leading cause of cancer‐related death. The NF‐κB transcription factor family subunit c‐Rel is typically protumorigenic; however, it has recently been reported as a

Plasma proteomic signature of decline in gait speed and grip strength

Aging Cell, Volume 21, Issue 12, December 2022., 2022
Several plasma proteins were associated with physical function decline in adults from middle to older age, including GDF‐15, pleiotrophin, and TIMP‐1 for gait speed decline, and CA III, CDON, and SMOC1 for grip strength decline. These novel proteomic biomarkers may by explored as future mechanisms and targets for age‐related functional decline ...

Dependence of protein-induced lipid bilayer deformations on protein shape [PDF]

, 2022
Membrane proteins typically deform the surrounding lipid bilayer membrane, which can play an important role in the function, regulation, and organization of membrane proteins. Membrane elasticity theory provides a beautiful description of protein-induced lipid bilayer deformations, in which all physical parameters can be directly determined from ...

Binding of anisotropic curvature-inducing proteins onto membrane tubes [PDF]

Soft Matter 18, 3384-3394 (2022), 2022
Bin/Amphiphysin/Rvs superfamily proteins and other curvature-inducing proteins have anisotropic shapes and anisotropically bend biomembrane. Here, we report how the anisotropic proteins bind the membrane tube and are orientationally ordered using mean-field theory including an orientation-dependent excluded volume.

Curvature sensing of curvature-inducing proteins with internal structure [PDF]

Phys. Rev. E 109, 024403 (2024), 2023
Many types of peripheral and transmembrane proteins can sense and generate membrane curvature. Laterally isotropic proteins and crescent proteins with twofold rotational symmetry, such as Bin/Amphiphysin/Rvs superfamily proteins, have been studied theoretically. However, proteins often have an asymmetric structure or a higher rotational symmetry.

Advanced Image Segmentation Techniques for Neural Activity Detection via C-fos Immediate Early Gene Expression [PDF]

arXiv, 2023
This paper investigates the application of advanced image segmentation techniques to analyze C-fos immediate early gene expression, a crucial marker for neural activity. Due to the complexity and high variability of neural circuits, accurate segmentation of C-fos images is paramount for the development of new insights into neural function.

In silico evidence that protein unfolding is as a precursor of the protein aggregation [PDF]

ChemPhysChem 2020, 21, 377, 2019
We present a computational study on the folding and aggregation of proteins in aqueous environment, as function of its concentration. We show how the increase of the concentration of individual protein species can induce a partial unfolding of the native conformation without the occurrence of aggregates. A further increment of the protein concentration

A novel methodology on distributed representations of proteins using their interacting ligands [PDF]

Bioinformatics 2018, 2018
The effective representation of proteins is a crucial task that directly affects the performance of many bioinformatics problems. Related proteins usually bind to similar ligands. Chemical characteristics of ligands are known to capture the functional and mechanistic properties of proteins suggesting that a ligand based approach can be utilized in ...
