PP2A Promotes the Symmetric Division of MUC1‐Dominant Cancer Stem‐Like Cells in Small Cell Lung Cancer

open access: yesAdvanced Science, EarlyView.
During the G2/M phase, mucin1 (MUC1) activates protein phosphatase 2A (PP2A), leading to reduced phosphorylation of protein kinase C ζ (PKCζ) and NUMB, which promotes symmetric division and expansion of cancer stem‐like cells (CSLCs), thereby driving tumorigenesis. Combined inhibition of the MUC1–PP2A axis using LB100/GO203 with etoposide restores PKCζ

Knowledge-based energy functions for computational studies of proteins [PDF]

open access: yes, 2006
This chapter discusses theoretical framework and methods for developing knowledge-based potential functions essential for protein structure prediction, protein-protein interaction, and protein sequence design. We discuss in some details about the Miyazawa-Jernigan contact statistical potential, distance-dependent statistical potentials, as well as ...

Small antimicrobial resistance proteins (SARPs): Small proteins conferring antimicrobial resistance [PDF]

open access: yesarXiv, 2023
Small open reading frames are understudied as they have been historically excluded from genome annotations. However, evidence for the functional significance of small proteins in various cellular processes accumulates. Proteins with less than 70 residues can also confer resistance to antimicrobial compounds, including intracellularly-acting protein ...

EGFR‐TKIs Induced DPP4 Drives Metabolic Reprogramming of Persister Cells in Lung Cancer

open access: yesAdvanced Science, EarlyView.
Drug‐tolerant persister (DTP) cells emerge early during EGFR‐TKI treatment, preceding the development of acquired resistance. Elevated DPP4 in DTP cells drives metabolic reprogramming and antioxidant adaptation, promoting cell survival under drug pressure.

Protein Inference and Protein Quantification: Two Sides of the Same Coin [PDF]

open access: yesarXiv, 2012
Motivation: In mass spectrometry-based shotgun proteomics, protein quantification and protein identification are two major computational problems. To quantify the protein abundance, a list of proteins must be firstly inferred from the sample. Then the relative or absolute protein abundance is estimated with quantification methods, such as spectral ...

Inhibition of SHP2-mediated dephosphorylation of Ras suppresses oncogenesis [PDF]

open access: yes, 2015
Ras is phosphorylated on a conserved tyrosine at position 32 within the switch I region via Src kinase. This phosphorylation inhibits the binding of effector Raf while promoting the engagement of GTPase-activating protein (GAP) and GTP hydrolysis.

When flames hit the brain, and the spark is far away: the role of PET-CT in diagnosing neurological Erdheim-Chester disease

open access: yesArquivos de Neuro-Psiquiatria
Erdheim-Chester disease (ECD) is a rare histiocytic disorder that poses diagnostic and therapeutic challenges. Neurological manifestations are characterized by involvement of the meninges, brainstem, and/or cerebellum, and the differential diagnoses ...

Is the intrinsic disorder of proteins the cause of the scale-free architecture of protein-protein interaction networks? [PDF]

open access: yesarXiv, 2006
In protein-protein interaction networks certain topological properties appear to be recurrent: networks maps are considered scale-free. It is possible that this topology is reflected in the protein structure. In this paper we investigate the role of protein disorder in the network topology.
