SPECT/CT imaging of EGFR-positive head and neck squamous cell carcinoma patient-derived xenografts with Pb-PSC-panitumumab in NRG mice.

Background: The objective of this research was the development and evaluation of Pb-labelled panitumumab (Pb-PSC-panitumumab) as an immuno-SPECT radioligand for the detection of EGFR + head and neck squamous cell carcinoma (HNSCC) in a patient-derived xenograft (PDX) mouse model. The 51.9 h physical half-life and favourable γ-emission (279 keV; 81%) of Pb offer an excellent opportunity for developing immuno-SPECT radioligands.

Immuno-PET Imaging of EGFR with Cu-NOTA Panitumumab in Subcutaneous and Metastatic Nonsmall Cell Lung Cancer Xenografts.

: About 65-90% of nonsmall cell lung cancer (NSCLC) express the epithelial growth factor receptor (EGFR) as a transmembrane protein that is activated by binding of specific ligands, including epidermal growth factor and transforming growth factor α (TGFα). Identifying EGFR as an oncogene has led to the development of anticancer therapeutics directed against EGFR, including the full-length human IgG monoclonal antibody panitumumab. The main goal of the present study was to investigate Cu-labeled panitumumab with immuno-PET in subcutaneous and metastatic EGFR-positive NSCLC xenografts.

Peptide-Drug Conjugate Targeting Keratin 1 Inhibits Triple-Negative Breast Cancer in Mice.

Selective delivery of chemotherapy to the tumor site while sparing healthy cells and tissues is an attractive approach for cancer treatment. Carriers such as peptides can facilitate selective tumor targeting and payload delivery. Peptides with specific affinity for the overexpressed cell-surface receptors in cancer cells are conjugated to chemotherapy to afford peptide-drug conjugates (PDCs) that show selective uptake by cancer cells.

Nano-Delivery of a Novel Inhibitor of Polynucleotide Kinase/Phosphatase (PNKP) for Targeted Sensitization of Colorectal Cancer to Radiation-Induced DNA Damage.

Inhibition of the DNA repair enzyme polynucleotide kinase/phosphatase (PNKP) increases the sensitivity of cancer cells to DNA damage by ionizing radiation (IR). We have developed a novel inhibitor of PNKP, i.e.

RGD peptide grafted polybutylene adipate--terephthalate/gelatin electrospun nanofibers loaded with a matrix metalloproteinase inhibitor drug for alleviating of wounds: an / study.

The objective of the present study was the fabrication of a wound dressing membrane based on RGD modified polybutylene adipate--terephthalate (PBAT)/gelatin nanofibrous structures loaded with doxycycline (DOX). This type of nanofiber for wound healing has not been reported so far and is quite novel. PBAT and gelatin nanofibers were separately electrospun using double needles electrospinning setup.
