Background:
Recent research has underscored the critical role of long non-coding RNAs (lncRNAs) in tumorigenesis and malignancy development. Nevertheless, the role of lncRNA cytoskeleton regulator RNA (CYTOR) in the progression of melanoma remains only partially elucidated. This research seeks to explore the impact of CYTOR on melanoma development and to elucidate the molecular mechanisms involved.
Methods:
In vitro and in vivo models were used to assess CYTOR expression levels by QPCR and Western blotting. Melanoma cell proliferation, migration, and invasion were assessed by CCK-8 assay, scratch wound assay and transwell invasion experiments. The mechanism of CYTOR promoting melanoma progression was verified in a xenograft tumor mouse model.
Results:
Our investigation identified a marked increase in CYTOR expression levels in both melanoma tissues and cells. Experiments conducted both in vitro and in vivo revealed that CYTOR markedly stimulated melanoma cell proliferation, migration, and invasion. Dual-luciferase reporter assays confirmed the direct binding of miR-485-5p to CYTOR, and glucose-6-phosphate isomerase (GPI) was identified as a direct target of miR-485-5p.

Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

02:15M-Cdk Drives Transition Into Mitosis
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.
