CXCR4 expression

MALAT1 silencing may repress CXCL12 induction on MM cell proliferation, invasion, and homing behavior by inhibiting CXCR4. MALAT1 may be a promising target for MM treatment.

Targeting CXCR4 with [64Cu]Cu-NOTA-CP01 for PET imaging of lymph nodes metastasis represents a promising approach that warrants further investigation. These findings have the potential to enhance diagnostic and therapeutic strategies for individuals with lymph nodes metastasis of ESCC.

Their expression can be recovered at later time-points, suggesting the presence of a negative feedback loop mechanism. In contrast, late response genes, which are continuously downregulated after MYB depletion, includes many genes involved in cell proliferation as well as TAL1 targets, thereby affecting the cellular phenotype.

Huayu Jiedu Decoction can inhibit the proliferative activity of U266 cells and induce programmed death. Its molecular mechanism may be related to regulating the expression of apoptotic proteins, inhibiting the activation of TLR4/NF-κB pathway and down-regulating the expression of HMGB1 and IL-6 mRNA.

Our research suggests that the complex interactions between CXCL12 and the various tumor and immune cell types contributes not only to the completion of the initial steps of the metastatic cascade, but also offers an immunological "sanctuary" to prometastatic tumor cells homed around TMEM doorways. Overall, our study enhances our current understanding on the mechanisms, via which CXCL12 orchestrates tumor cell behavior and immune dynamics, potentially guiding future thera- peutic strategies to combat breast cancer metastasis and improve anti-tumor immunity.

Besides, fused in sarcoma (FUS) was confirmed to bind to USP1 and stabilized its mRNA expression, and could regulate CXCR4 via USP1. In conclusion, USP1 stabilized CXCR4 by removing ubiquitination on CXCR4, thereby promoting ESCC cell proliferation, invasion, and immune escape in vitro, and tumor growth in vivo.

MIP-1α expression was significantly correlated with average CXCR4 CAML expression (P = 0.003). We discovered larger CAML size was associated with SAT-dominant obesity with increased macrophage-related and proinflammatory markers in obese than in nonobese breast cancer patients.

In conclusion, our comprehensive investigation highlights CXCR4 as a key mediator of TME dynamics and immune modulation in GC. Targeting CXCR4 presents a promising therapeutic strategy to slow tumor progression by reducing Tregs-mediated immune exhaustion and TME heterogeneity, positioning it as a novel therapeutic target in GC treatment.

Preclinical and pilot clinical studies demonstrated its feasibility and potential application in precise diagnosis for not only lymphoma but also SCLC and glioma. [18F]AlF-NOTA-QHY-04 PET/CT can also provide a complementary mapping for brain tumors to [18F]FDG PET/CT.

Selective p53 knockdown led to positive therapeutic outcomes in mice with cisplatin-induced AKI, as seen by reduced tubular cell death, renal injury, inflammation, and overall improved renal function. These findings indicate that IC is a promising new carrier for renal-targeted delivery of RNA for the treatment of AKI.

Inhibition of CXCR4 expression also reduced the invasion of cancer cells by CXCL12. In conclusion, our results suggest that ISO is a novel inhibitor to regulate CXCR4 expression and the key molecule contributing to antitumor activity.

We successfully established an in vivo CAM-PDX model based on CRC PDOs. The histomorphological features and target protein expression of the original patient's tissue were mirrored in the in vitro PDOs, and particularly in the in vivo CAM-PDXs. The [68Ga]Ga-Pentixafor uptake patterns were comparable between in vitro, in ovo and clinical data and 2-[18F]FDG was avidly taken up in the patient's liver metastasis and CAM-PDXs. We thus propose the CAM-PDX model as an alternative in vivo model with promising translational value for CRC patients.
