Listening to conversations between a mother and her unborn child on the cellular level could inform how the pregnancy is going and prevent complications. Three scientific groups from the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), in collaboration with Wayne State University and Michigan State University, have used single-cell RNA sequencing techniques to decipher these words, identify the cellular language of these interactions in the placenta and establish a cellular atlas.
Researchers from Hebei Medical University and affiliated organizations have discovered new folate receptor (FR)-targeted fluorescent probes for tumor detection.
Researchers at Albert-Ludwigs-Universität Freiburg and Deutsches Krebsforschungszentrum (DKFZ) have disclosed drug conjugates comprising fluorescent-labeled dye covalently linked to a radionuclide and a ligand targeting glutamate carboxypeptidase II (NAALADase; NAAG peptidase, FOLH1; PSMA) acting as positron-emission tomography (PET) and fluorescent imaging agents for diagnosis and treatment of prostate cancer.
Fibroblast activation protein (FAP) is a serine protease that is highly overexpressed in the stroma of most epithelial-derived tumors – including pancreatic, breast and colorectal cancers – in the context of cancer-associated fibroblasts (CAFs).
Researchers at F. Hoffmann-La Roche Ltd. and Hoffmann-La Roche Inc. have synthesized radiolabeled compounds acting as GABA(A) receptor subunit α2β2γ1 (GABRA2) positive allosteric modulators acting as positron-emission tomography (PET) and autoradiography imaging agents reported to be useful for the diagnosis of neurological disorders.
Previous research has shown high expression of angiotensin-converting enzyme 1 (ACE1) in the triple-negative breast cancer (TNBC) cell line MDA-MB-231, suggesting the potential of ACE1 as a novel target for this disease. In the current study, researchers from Peking University Cancer Hospital presented the discovery of [68Ga]DOTA-BPP, a novel peptide nuclide molecular imaging probe targeting ACE1 for the imaging of TNBC.
Researchers from University Hospital Basel and Universitätsklinikum Ulm presented the discovery of novel radiotheragnostic candidates targeting C-X-C chemokine receptor 4 (CXCR4), which is highly expressed in various cancers and has been linked to poor prognosis.
Researchers from Huazhong University of Science and Technology presented the discovery and preclinical evaluation of a novel peptide PET tracer targeting LAG-3, [68Ga]NOTA-XH05, being developed as a candidate for evaluating the efficacy of cancer immunotherapy.
The discovery of new 68Ga-labeled CD38-targeted peptides for PET imaging was recently discussed by researchers from Peking University First Hospital and China National Center For Nanoscience & Technology.
