Moreover, doxorubicin (DOX) was remote-loaded into LIPOTAC vesicle via an ammonium sulfate gradient method for enhancing the anti-tumor effect of LIPOTAC, named DOX@LIPOTAC...The persistent HK-2 degradation strategy boosted tumor aerobic glycolysis inhibition for synergistic enhancement of tumor chemotherapy. Therefore, our study offers new insights into how to regulate tumor glucose metabolism through an innovative protein degradation strategy for cancer treatment.

Our findings demonstrate that BenZ inhibits the kinase activity of HK2, reduces ATP level and cisplatin efflux, as well as alleviates NF-κB activation. These multifaceted actions enhance the anticancer efficacy of cisplatin in NSCLC cell models, indicating its potential as an effective adjunct therapy.

It was found that the combination significantly suppressed the tumour growth in SCC25 cell xenograft mouse model. Our findings suggested that targeting HK2 and modulating glycolysis may offer a promising avenue for improving the therapeutic outcomes of TCS-based anticancer treatments.

Furthermore, in vivo experiments in nude mice illustrated that HK2 O-GlcNAcylation could stimulate tumor growth in NSCLC. These results suggested that HK2 may impact mitochondrial dynamics in NSCLC through its O-GlcNAcylation, thereby contributing to the progression of NSCLC.

Consequently, this impedes M1-like macrophage polarization. Our study highlights the critical role of fructose as a signaling molecule that impairs the polarization of M1-like macrophages for tumor growth.

Furthermore, HK2 was shown to inhibit cell proliferation of U87-MG gliomas, which might depend on Notch signaling activity. Together, our findings suggest the involvement of Notch-mediated HK2 suppression in an adaptive mechanism of U87-MG glioma cells to nutrient-poor conditions.

Taken together, 8Ae might inhibit glycolysis by stimulating the shedding of HK2 from mitochondria and promoting mitochondria-regulated apoptosis to inhibit the proliferation of A549 cells. This article provides a research basis for bibenzyl compounds as new small molecule drugs for lung cancer.

Utilizing proteolysis-targeting chimera (PROTAC) HK2 degraders, we also found that paclitaxel sensitivity, viability, and oxygen consumption rates under paclitaxel treatment were restored by HK2 degraders treatment, and decreased downstream expression of the ABC and SLC transporters was shown in OCCC cells. Taken together, these findings highlight the paclitaxel resistance in OCCC elucidates metabolic alternation, including ABC- and SLC- drug transporters, thereby affecting glycolysis metabolism in response to paclitaxel resistance, and HK2 may become a novel potential therapeutic target for paclitaxel resistance.

Consistently, the miR139a-5p mimic enhanced the suppression of β-catenin, c-Myc, and HK2, while the miR193a-5p inhibitor reversed the ability of GF2 to attenuate the expression of β-catenin, c-Myc, and HK2 in HeLa cells. Overall, these findings suggest that GF2 induces apoptosis via the activation of miR193a-5p and the inhibition of β-catenin/c-Myc/HK signaling in cervical cancer cells.

Identifying patients with high HK2 expression may pinpoint a higher-risk cohort, paving the way for comprehensive prospective studies that could advocate for intensified monitoring and more aggressive therapeutic regimens. Furthermore, the targeted inhibition of HK2 could hold promise as a strategy to potentially enhance patient outcomes.

We find that the peptide carrying the MMP2/9 cleavage site is the most effective, both in inhibiting the in vitro tumorigenicity of MPNST cells and in hampering their growth in mice. Our data indicate that detaching HK2 from MAMs could pave the way for a novel anti-MPNST therapeutic strategy, which could be flexibly adapted to the protease expression features of the tumor microenvironment.
