Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

Molecular Mechanism for Eliminylation, a Newly Discovered Post-Translational Modification

, 2016
The newly discovered bacterial phosphothreonine lyases perform a post-translational modification of host cell signaling proteins through a novel catalytic mechanism that irreversibly removes the phosphate group from a phosphorylated threonine via β ...

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer

Molecular Oncology, EarlyView.
Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

Identification and characterization of O-GlcNAc modifications of a conserved orthopoxvirus core protein

Journal of Virology
O-GlcNAcylation, a post-translational modification consisting of O-linked N-acetylglucosamine attached to serine and threonine residues, occurs in thousands of cytoplasmic, nuclear, and mitochondrial proteins but has been reported for relatively few ...

Analysis of post-translational modifications by LC-MS/MS.

, 2010
Post-translational modifications are highly dynamic and known to regulate many cellular processes. Both the site and the stoichiometry of modification of a given protein sequence can have profound effects on the regulation of protein function.

USP7 inhibits FOXO1 activity in chronic lymphocytic leukaemia cells enhancing cell survival

Molecular Oncology, EarlyView.
CLL cells rely on BCR‐mediated signalling for survival and proliferation in part through suppression of FOXO1. FOXO1 activity is regulated by a plethora of post‐translational modifications including phosphorylation and ubiquitination. We demonstrated that dual inhibition of BCR signalling and the deubiquitinase USP7 activates FOXO1, modulating its ...

Discovery and Identification of Serum Succinyl‐Proteome for Postmenopausal Women with Osteoporosis and Osteopenia

Orthopaedic Surgery, 2019
Objective For the purpose of providing evidence for the treatment of osteoporosis and osteopenia, this study retrospectively identified succinylation‐modified sites and proteins in postmenopausal women, and bioinformatics analysis were performed. Methods

Tumour‐proximal deep serum proteomics identifies biomarkers associated with ovarian cancer

Molecular Oncology, EarlyView.
New biomarkers are needed for early ovarian cancer detection. Ovarian (tumour‐proximal) and peripheral vein serum from healthy women and patients with benign or malignant tumours underwent nanoparticle‐enriched deep proteomics. Ovarian serum yielded more protein identifications and revealed tumour‐reflective signatures.

Immunoinflammation and post-translational modifications in the aging process

Journal of Translational Medicine
Aging is an intrinsic biological decline marked by multidimensional alterations spanning molecular, cellular, tissue, and organ levels. One hallmark of aging is the progressive deterioration of immune function, a condition referred to as immunosenescence.

The impact of leukocyte‐associated RNA retention on platelet RNA‐based cancer detection

Molecular Oncology, EarlyView.
Platelets carry RNA signals that may help detect cancer, but platelet samples can also retain RNA from white blood cells. We found that this retained white blood cell signal did not significantly affect machine learning cancer classification, suggesting that the cancer‐related RNA signal in platelets is largely independent of leukocyte‐associated RNA ...
