TIMP1 expression

The STAT3 inhibitor silibinin enhances the preclinical efficacy of the combined PD-1/CTLA4 immune checkpoint blockade, providing a rationale to translate the combination therapy into clinical use for this underserved patient group with poor prognosis. See related article by Priego et al., p. 179.

T cell densities in tumor tissue positively correlated with tumor stromal TIMP1 expression and negatively with tumor epithelial TIMP1 expression. Serum TIMP1 levels show promise as a prognostic marker for colorectal cancer and correlate with systemic inflammatory markers, but do not correlate with TIMP1 expression in tumor tissue.

In addition, we found that EV and TIMP1 could inhibit Notch1 and downstream targets Hes1, P16, P21, and P53. Collectively, our data suggests that both AMSC-EV and HUMSC-EV attenuate skin photoaging through TIMP1/Notch1.

Subsequent rescue experiments revealed that TIMP1 overexpression reversed the impact of circSCAF8 shRNA viruses on gastric cancer. In conclusion, circSCAF8 expression was elevated in gastric cancer, and circSCAF8 shRNA viruses inhibited gastric cancer growth and metastasis by upregulating TIMP1 expression via miR-1293.

Then we detected 6 repurposable drug molecules (Entrectinib, Imatinib, Ponatinib, Sorafenib, Retevmo, and Pazopanib) by molecular docking with KGs-mediated receptor proteins, ADME/T analysis, and cross-validation with the independent receptors. Therefore, these findings might be useful resources for wet lab researchers and clinicians to consider an effective treatment strategy against THCA.

Altogether, exercise preconditioning had protective effects on CIRI by restraining TIMP1, which provided new therapeutic strategies for preventing CIRI.

Furthermore, GA-017 increased ABL2 expression in MGC-803 cells and counteracted the effects of si-ABL2 on cell migration, invasion and proliferation. These findings indicated that heightened ABL2 expression could activate TGF-β/SMAD2/3 and YAP signaling pathway, promoting epithelial mesenchymal transformation (EMT), and enhancing multiplication, metastasis, and invasion in GC cells.

Furthermore, TIMP1 expression was associated with poor prognosis in GC patients. TIMP1 expression was related to tumor differentiation and poor prognosis but not sex, age, TNM stage, depth of invasion, lymph node metastasis or tumor size.

Mechanistically, HHT exerted anti-TC effects by downregulating TIMP1 expression and then inactivating the FAK/PI3K/AKT signaling pathway. Taken together, our study demonstrated that HHT could inhibit TC progression by inhibiting the TIMP1/FAK/PI3K/AKT signaling pathway.

The following markers can be helpful when lesions cannot be differentiated; increased staining proportions and intensity of MMP-9 in both lesion and stromal cells favor MM in cases where MM and IDN cannot be differentiated. The increased MMP-13 staining proportion of lesion cells can favor DN in cases where the pathologist cannot differentiate DN and MM. Intense expression of MMP-21 by lesion cells can be a potential marker for evaluating the lesion in favor of DN in cases where DN and IDN cannot be differentiated. The high expression intensity of TIMP-1 in lesion cells can favor DN in cases where there is ambiguity between DN and MM. High expression proportion and intensity of stromal cells of TIMP-1 can be useable in favor of MM in cases where MM and DN cannot be differentiated.

PLE0 markedly suppressed JNK phosphorylation, and JNK knockdown significantly restored PLE0-regulated MMP-2/-9 and TIMP-1 expression. Collectively, our data indicate that PLE0 exerts an anti-metastatic effect in human colon cancer cells by inhibiting epithelial-mesenchymal transition and MMP-2/9 via downregulation of GSK3β/β-catenin and JNK signaling.

SPARC, TIMP1, THBS2 and other DEGs are probably involved in GC occurrence and progression and may serve as potential candidate molecular markers for early diagnosis and prognostic evaluation of GC.
