Abstract:
Recent studies have highlighted the impact of copper-induced cell death (cuproptosis) on cancer progression, prognosis, and treatment, but it remains unclear whether cuproptosis-related genes (CRGs) play any role in the glioma tumor microenvironment (TME). The CRGs expression patterns in TCGA glioma samples were evaluated based on genetic and transcriptional alterations identifying three different molecular groupings and showing that CRGs changes were linked to clinical characteristics, prognosis, and TME infiltration. Machine learning algorithms were then used to develop an overall survival score for cuproptosis-related prognostic genes (CRPGs), and its prognostic ability was validated for glioma patients. An elevated CRPGs score indicates a heightened mutation burden, increased glioma metabolism, compromised immunity, and strong correlation with both the cancer stem cells (CSC) index and medication sensitivity to chemotherapeutics. This extensive examination of CRGs in gliomas showed their possible significance in the tumor microenvironment as well as their prognostic value. This extremely precise CRPGs nomogram has furthered our understanding of cuproptosis in gliomas, which will allow new approaches to prognosis and immunotherapy development.

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

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...

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.
Such genes that act...
