Summary
This summary is machine-generated.This study reveals that has_circ_0002360 promotes lung adenocarcinoma (LAC) progression by regulating miR-762 and PODXL. Targeting this circular RNA may offer a new therapeutic strategy for LAC patients.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Circular RNAs (circRNAs) are implicated in cancer progression, but their role in lung adenocarcinoma (LAC) is not fully understood.
- Previous work identified high expression of has_circ_0002360 in LAC tissues.
- This study aimed to elucidate the specific function of has_circ_0002360 in LAC.
Purpose Of The Study
- To investigate the role of has_circ_0002360 in lung adenocarcinoma (LAC).
- To explore the molecular mechanism by which has_circ_0002360 influences LAC progression.
- To identify potential therapeutic targets for LAC.
Main Methods
- RNA interaction analysis using bioinformatics tools (TargetScan, miRanda) and luciferase reporter assays.
- Quantification of has_circ_0002360 and miR-762 expression via qRT-PCR in LAC tissues and cell lines.
- Assessment of cell proliferation, migration, and invasion using CCK8, wound healing, and Transwell assays.
- Immunohistochemistry (IHC) to confirm PODXL expression in clinical samples.
Main Results
- has_circ_0002360 and PODXL were significantly overexpressed in LAC tissues, while miR-762 was repressed.
- Downregulation of has_circ_0002360 or upregulation of miR-762 inhibited LAC cell proliferation, migration, and invasion.
- has_circ_0002360 was found to upregulate PODXL by targeting miR-762, thereby promoting LAC progression.
Conclusions
- The has_circ_0002360/miR-762/PODXL axis plays a crucial role in the progression of lung adenocarcinoma.
- has_circ_0002360 is identified as a novel oncogenic circular RNA in LAC.
- This axis represents a potential therapeutic target for lung adenocarcinoma treatment.

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
In most mammals, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY). The X chromosome contains significantly more genes than the Y chromosome. Therefore, to prevent an excess of X chromosome-linked gene expression in females, one of the two X chromosomes is randomly silenced during early development....
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
