Plasmids silencing UBE2L3 and negative control plasmids were transfected into U2OS and HOS cells. The cells were divided into the following groups: U2OS cell group, HOS cell group, si-NC-U2OS cell group, si-UBE2L3-U2OS cell group, si-NC-HOS cell group, and si-UBE2L3-HOS cell group. Cell viability and proliferation capacity were measured using the Tunnel method and clonogenic assay. Cell migration and invasion abilities were assessed by Transwell and scratch assays. Cell apoptosis was analyzed by flow cytometry, and ROS levels were detected using immunofluorescence. The oxidative stress levels in various cell groups and the expression changes of necroptosis-related proteins were assessed by PCR and WB. Through these experiments, we aim to evaluate the impact of oxidative stress on necroptosis and uncover the specific mechanisms by which targeted regulation of oxidative stress promotes tumor cell necroptosis as a potential therapeutic strategy for osteosarcoma.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;The mRNA expression levels of UBE2L3 in human osteosarcoma cell lines were significantly higher than those in human osteoblast hFOB1.19 cells (p &lt;0.01).

Tunnel assay results showed a significant increase in the number of red fluorescent-labeled cells in si-UBE2L3 groups compared to si-NC groups in both cell lines, suggesting a pronounced inhibition of cell viability. Transwell assay demonstrated a significant reduction in invasion and migration capabilities of si-UBE2L3 groups in osteosarcoma cells. The clonogenic assay revealed significant suppression of proliferation and clonogenic ability in both U2OS and HOS cells upon UBE2L3 knockdown.

Of all the characteristics of cancer, metastasis is believed to be the hallmark as it is responsible for the highest number of cancer-related deaths. In connection with this, Matrix metalloproteinases (MMPs), that has a role in metastasis, are one of the novel therapeutic targets. MMPs belong to the family of zinc-dependent endopeptidases and are capable of degrading the components of the extracellular matrix (ECM). The role of MMPs in ECM remodeling includes tissue morphogenesis, uterine cycling, growth, tissue repair, and angiogenesis. During pathological conditions, MMPs play a critical role in the excessive degradation of ECM which includes arthritis, tumour invasion, tumour metastasis, and several other autoimmune disorders. Moreover, they are believed to be involved in many physiological aspects of the cell, such as proliferation, migration, differentiation, angiogenesis, and apoptosis. It is reported that dysregulation of MMP in a variety of cancer subtypes have a dual role in tumour growth and metastasis processes. Further, multiple studies suggest the therapeutic potential of targeting MMP in invading cancer. The expression of MMP-2 correlates with the clinical characteristics of cancer patients, and its expression profile is a new diagnostic and prognostic biomarker for a variety of human diseases.
