Long non-coding RNAs (lncRNAs) have been linked to tumorigenesis. However, the role of LINC01210 in colorectal cancer (CRC) remains unclear. Relative levels of LINC01210 in CRC tissues and adjacent tissues were determined. Proliferative, migratory, and invasive abilities were examined in HCT116 cells and LoVo cells after silencing or overexpressing LINC01210. The interaction between LINC01210 and SRSF3 was explored by ChIP-PCR. Upregulated LINC01210 was associated with metastasis and advanced stage of CRC. Silencing LINC01210 attenuated proliferative, migratory, and invasive abilities in LoVo cells, while overexpressing LINC01210 promoted proliferative, migratory, and invasive abilities in HCT116 cells. Mechanism study revealed that LINC01210 increased the expression of SRSF3 by recruiting mixed lineage leukaemia protein-1, which upregulated the trimethylation of H3K4 me3 on SRSF3 promoter. Silencing SRSF3 reversed the effects of LINC01210 on CRC cells. In conclusions, LINC01210 accelerated proliferation and invasion in CRC cells through epigenetically upregulating SRSF3, and may be a potential therapeutic target for CRC treatment.

Lung cancer is the most common type of malignant tumor worldwide. Plasma-activated medium (PAM) is an innovative cancer treatment method that has received considerable scientific attention. The objective of this study is to evaluate the effects of PAM on the anti-tumor characteristics of non-small cell lung cancer (NSCLC) cells in two-dimensional (2D) and three-dimensional (3D) cultures.

Cancer stem cells (CSCs) account for 0.01 to 2% of the total tumor mass; however, they play a key role in tumor progression, metastasis and resistance to current cancer therapies. The generation and maintenance of CSCs are usually linked to the epithelial-mesenchymal transition (EMT), a dynamic process involved in reprogramming cancer cells towards a more aggressive and motile phenotype with increased stemness potential.

is a subendemic species of the Central Apennine, valued locally for its applications in ancient and traditional medicine for its antibacterial, antifungal, anthelmintic, digestive, and antispasmodic effects. Several of these properties are also found in other species within the same genus, including recent findings highlighting their anti-tumor actions. However, the presence of cytotoxic or anti-tumor activity has never been studied in .

Metabolic reprogramming is considered one of the hallmarks of cancer in which cancer cells reprogram some of their metabolic cascades, mostly driven by the specific chemical microenvironment in cancer tissues. The altered metabolic pathways are increasingly being considered as potential targets for cancer therapy. In this view, Aldolase A (ALDOA), a key glycolytic enzyme, has been validated as a candidate oncogene in several cancers.
