Summary
Circular RNA circ_0001387 promotes hepatocellular carcinoma (HCC) progression by sponging miR-4324 and upregulating MCM6. This novel axis offers a potential therapeutic target for HCC intervention.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Hepatocellular carcinoma (HCC) has a poor prognosis, with circular RNAs (circRNAs) playing a key role in its development.
- This study investigates the function of a novel circRNA, circ_0001387, in the pathophysiology of HCC.
Purpose of the Study:
- To elucidate the role and mechanism of circ_0001387 in hepatocellular carcinoma progression.
- To identify the circRNA-miRNA-mRNA axis involved in HCC pathogenesis.
Main Methods:
- Bioinformatics analysis of GEO databases to identify the circRNA-miRNA-mRNA axis.
- In vitro functional assays including cell proliferation, migration, invasion, apoptosis, and cell cycle analysis.
- In vivo tumor growth assessment in nude mouse xenografts and interaction validation using dual-luciferase reporter assays.
Main Results:
- Circ_0001387 and MCM6 were found to be upregulated in HCC tissues and cells, while miR-4324 was downregulated.
- Overexpression of circ_0001387 promoted HCC cell proliferation, migration, invasion, and tumor growth, while inhibiting apoptosis.
- Circ_0001387 acts as a sponge for miR-4324, leading to the upregulation of its target gene, MCM6.
Conclusions:
- Circ_0001387 promotes HCC progression through the miR-4324/MCM6 axis.
- This pathway represents a potential therapeutic target for HCC intervention.
- Further clinical validation is needed to establish this axis as a reliable biomarker for HCC.

mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Cirrhosis II: Pathophysiology
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
Abnormal Proliferation
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 daughter...
PI3K/mTOR/AKT Signaling Pathway
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a rapamycin-insensitive companion...
