PDGFRB (Platelet Derived Growth Factor Receptor Beta)

Taken together, Ce6-mediated sublethal PDT under specific conditions further promotes CAF activation by oxidative stress and the downstream MAPK signaling pathway, thereby regulating the lung cancer microenvironment. As a study deciphering PDT-mediated regulation of CAF in the tumor immune microenvironment, our work constitutes a pioneering and highly significant exploratory effort.

We examine how these pathways orchestrate pericyte recruitment, proliferation, differentiation, and phenotypic transitions through complex downstream signaling cascades involving kinases, transcription factors, and mechanotransduction mechanisms. The review further explores the multifaceted roles of pericytes in major pulmonary diseases, including acute lung injury and acute respiratory distress syndrome (ALI/ARDS), pulmonary fibrosis, pulmonary arterial hypertension (PAH), lung cancer, and lung infections.

DFSP appears biologically optimized for local stromal infiltration rather than systemic dissemination. Rare metastatic progression likely reflects the acquisition of additional molecular and microenvironmental features, particularly in fibrosarcomatous transformation. Further investigation into stromal interactions and vascular access mechanisms is warranted.

Critical pathways, encompassing the PI3K-Akt, AGE-RAGE, and proteoglycans pathways, may contribute to the interconnection between GC and depression. These findings illuminate potential molecular linkages between GC and depression, though additional investigation is required to elucidate the underlying mechanisms.

Together, these findings identify AKR1C3 as a candidate functional target of cypermethrin and suggest that AKR1C3 may be involved, at least in part, in cypermethrin-induced CRC-relevant cellular injury and oxidative stress. This study provides an exploratory framework for identifying exposure-related molecular targets linking foodborne pesticide residues to CRC-associated biological alterations.

To determine whether a similar BRCA2 variant was present in other lung cancer patients, 123 LUAD cases were analyzed, and one (0.81%) possessing a truncating BRCA2 variant (p.Q1429FfsTer20) without any typical driver mutations was identified. BRCA2 GPVs may represent putative pathogenic mutations, and thus be potential molecular targets for future treatment of LUAD.

Fibroblasts internalized migrasomes and acquired a CAF-like phenotype, showing enhanced migration, elevated secretion of IL-1β/TGF-β, and increased CAF marker expression (α-SMA, COL1A1, COL3A1, FAP, PDGFRβ), with effects most pronounced under hypoxic migrasome treatment. This study characterized hypoxic migrasome whole transcriptome landscapes and suggested that hypoxic migrasomes may promote CAF-like changes in vitro, uncovering a novel ESCC-tumor microenvironment interaction mechanism and offering new perspectives for ESCC research.

The five biomarkers provide valuable insights for the early screening, diagnosis, and treatment of STAD.

Rescue experiments demonstrated that U0126 phenocopied HL-RG effects, while EGF significantly reversed HL-RG-induced functional changes and p-ERK reduction, confirming that HL-RG acts through the MAPK/ERK pathway. HL-RG exerts anti-GC effects by targeting the MAPK pathway and its hub genes, providing a scientific basis for its clinical application.

[68Ga]Ga-NOTA-ATH001 is a novel, high affinity PDGFRβ-targeting PET tracer that enables in vivo PET imaging of mesenchymal cells in health and disease. Although it does not outperform its DOTA-conjugated analogue, the NOTA chelator offers practical advantages, such as convenient Al18F or 64Cu radiolabeling.

Wogonin exerts remarkable antitumor effects against TC by binding to PDGFRB, leading to its downregulation, and subsequently suppressing the PI3K/AKT pathway. Furthermore, PDGFRB upregulation contributes to lenvatinib resistance in TC, while wogonin partially reverses this resistance in a PDGFRB-dependent manner.
