Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining
Molecular Oncology, EarlyView.IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Neuropeptide conversion to bioactive fragments : an important pathway in neuromodulation
, 2003 Biosynthetic pathways for the formation of neuroactive peptides and the processes for their inactivation include several enzymatic steps. In addition to enzymatic processing and degradation, several neuropeptides have been shown to undergo enzymatic ...

Development of human monoclonal antibodies against TARM1 by yeast display
FEBS Open Bio, EarlyView.Human monoclonal antibodies against TARM1 are generated by yeast display‐guided selection. These antibodies bind to soluble and cell‐surface forms of TARM1. Also, these antibodies exhibit agonistic activity in the NFAT‐GFP reporter assay, indicating that TARM1 signaling can be functionally modulated by antibodies and suggesting TARM1 as a potential ...

Improved Detection and Fragmentation of Disulphide-Linked Peptides [PDF]
Methods and Protocols, 2018 Characterisation of peptides containing intact disulphide bonds (DSBs) via mass spectrometry is challenging. Our study demonstrates that the addition of aniline to alpha-cyano-4-hydroxycinnamic acid improves detection and fragmentation of complex DSB peptides by matrix-assisted laser desorption/ionization, tandem time-of-flight mass spectrometry (MALDI-

In vitro evaluation of leptin fragments activity on the ob receptor
, 2008 In an attempt to identify regions in the leptin molecule responsible for its bioactivity, we tested six related-leptin peptide fragments denoted: Ae-hLEP(23-47)-NH(2) (I), Ac-hLEP(48-71)-NH(2) (II), Ac-hLEP(72-88)-NH(2) (III), Ac-hLEP(92-115)-NH(2) (IV),

Screening and epitope characterization of Nidogen‐2‐specific nanobodies
FEBS Open Bio, EarlyView.Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

ECD-like peptide fragmentation at atmospheric pressure [PDF]
International Journal of Mass Spectrometry, 2012 Fragmentation of multiply-charged peptide ions via interaction with products of gas discharge at atmospheric pressure conditions was studied using ion mobility separation - fragmentation cell - linear ion trap mass spectrometer. The observed fragmentation spectra mainly consisted of c- type ions that are specific to electron capture dissociation ...
