Lipid metabolism reprograming by SREBP1‐PCSK9 targeting sensitizes pancreatic cancer to immunochemotherapy

Cancer Communications, EarlyView.
Abstract Background Pancreatic cancer's aberrant lipid metabolism fuels cell growth, invasion, and metastasis, yet its impact on immune surveillance and immunotherapy is unclear. This study investigated how sterol regulatory element‐binding transcription factor 1 (SREBP1)‐driven lipid metabolism affects the tumor microenvironment (TME) in pancreatic ...

Artificial Intelligence Transforming Post-Translational Modification Research

Bioengineering
Post-Translational Modifications (PTMs) are covalent changes to amino acids that occur after protein synthesis, including covalent modifications on side chains and peptide backbones.

A Curated Rotamer Library for Common Post-Translational Modifications of Proteins [PDF]

arXiv
Sidechain rotamer libraries of the common amino acids of a protein are useful for folded protein structure determination and for generating ensembles of intrinsically disordered proteins (IDPs). However much of protein function is modulated beyond the translated sequence through thFiguree introduction of post-translational modifications (PTMs). In this

A tailored phospho‐p53 library probes antibody specificity and recognition limitations

ChemBioChem, Accepted Article.
The tumour suppressor protein p53, known as the "guardian of the genome", is regulated by a complex network of posttranslational modifications (PTMs). Phosphorylations at 7 Ser/Thr residues within the N‐terminal transactivation domain 1 (TAD1) play a role in p53 activation, yet their precise mechanisms of action remain elusive due to challenges in ...

SAPNet: a deep learning model for identification of single-molecule peptide post-translational modifications with surface enhanced Raman spectroscopy [PDF]

arXiv
Nanopore resistive pulse sensors are emerging technologies for single-molecule protein sequencing. But they can hardly detect small post-translational modifications (PTMs) such as hydroxylation in single-molecule level. While a combination of surface enhanced Raman spectroscopy (SERS) with plasmonic nanopores can detect the small PTMs, the blinking ...

Comparative study of raw and thermally treated peanut major allergen post- translational modifications (PTMs) [PDF]

, 2019
Introduction. Peanut allergy affects a large portion of world population causing reactions rangingfrom mild to severe. Major peanut allergen IgE epitopes are well characterized but little is knownabout their post-translational modifications (PTM) and how they are affected by thermaltreatment.

Advancing the Exploration of the Ubiquitin‐like Protein FUBI with Synthetic Chemical Tools

ChemBioChem, Accepted Article.
The Ubiquitin‐like protein FUBI is encoded in humans by the FAU gene, whose down‐regulation in prostate, ovarian and breast cancer is significantly associated with poor prognosis. Despite its implications in disease progression, the regulatory mechanisms orchestrated by FUBI remain elusive. To address this knowledge gap, we developed a linear synthetic

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain

Developmental Dynamics, EarlyView.
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

The link of FOXO1 and FOXO4 transcription factors to development of the lens

Developmental Dynamics, EarlyView.
Abstract Background The FOXOs regulate the transcription of many genes, including ones directly linked to pathways required for lens development. However, this transcription factor family has rarely been studied in the context of development, including the development of the lens.
