Background:
Research has revealed that long non-coding RNAs (lncRNAs) are intimately associated with the occurrence, development, and metastasis of tumors through their regulation of gene expression. The lncRNA LINC00880 is important for colorectal cancer (CRC) occurrence and development. Our research aimed to explore the roles of LINC00880 in CRC progression.
Methods:
The expression of LINC00880 in CRC cells and tissues was first measured using quantitative reverse transcription polymerase chain reaction (qRT-PCR) and the prognosis of CRC patients was then investigated using the Kaplan-Meier method. The impacts of LINC00880 on CRC growth were evaluated by a series of in vitro and in vivo assays. Mechanistically, RNA sequencing (RNA-seq) technology and transcriptome analysis experiments were employed to validate the impact of LINC00880 on cell cycle pathway.
Results:
In this study, we have demonstrated, for the first time, that LINC00880 is significantly overexpressed in CRC and is associated with poor patient survival. Functional assays indicated that LINC00880 promotes the growth of CRC cells both in vitro and in vivo. Furthermore, RNA-seq has revealed the impact of LINC00880 on the cell cycle and DNA replication pathways, and identified MCM3 as a potential downstream target of LINC00880.
Conclusions:
Our findings indicate that LINC00880 is upregulated in CRC and promotes tumor growth.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

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...
