Summary
This summary is machine-generated.Circular RNA TP63 (circTP63) promotes prostate cancer (PCa) progression by interacting with miR-421 and VAMP-associated protein A (VAPA). Silencing circTP63 inhibits tumor growth, suggesting circTP63 as a potential therapeutic target for PCa.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Circular RNAs (circRNAs) play a significant role in cancer development.
- circTP63 is found at higher levels in prostate cancer (PCa) tissues than in normal tissues.
- The specific function of circTP63 in PCa remains largely unknown.
Purpose Of The Study
- To investigate the role and mechanism of circTP63 in prostate cancer progression.
- To explore circTP63 as a potential diagnostic and therapeutic target for PCa.
Main Methods
- Quantitative reverse transcription PCR (qRT-PCR) to measure circTP63 and miR-421 expression.
- In vitro assays (CCK-8, apoptosis, transwell) to assess PCa cell proliferation, migration, and invasion.
- Dual-luciferase reporter assays and Western blotting to elucidate molecular interactions.
- Xenograft animal models to evaluate circTP63's in vivo effects.
Main Results
- circTP63 expression was elevated, while miR-421 was decreased in PCa tissues.
- circTP63 significantly enhanced PCa cell proliferation and metastasis in vitro.
- circTP63 promotes PCa by binding to miR-421, releasing VAMP-associated protein A (VAPA).
- In vivo, circTP63 silencing markedly suppressed PCa progression.
Conclusions
- circTP63 acts as an oncogenic circRNA in prostate cancer.
- circTP63 facilitates PCa progression via the circTP63/miR-421/VAPA axis.
- circTP63 represents a promising diagnostic biomarker and therapeutic target for PCa.

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.
The mTOR pathway or the...
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...
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...
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
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...
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...
