Summary
This summary is machine-generated.Long noncoding RNA LINC02257 promotes colorectal cancer liver metastasis by upregulating the JNK pathway. Targeting this LINC02257/JNK axis offers a potential therapeutic strategy for colorectal cancer liver metastases.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Long noncoding RNAs (lncRNAs) are key regulators in colorectal cancer (CRC) progression.
- The specific roles of lncRNAs in colorectal cancer liver metastases (CRLMs) are not well understood.
Purpose Of The Study
- To investigate the expression patterns and functions of lncRNAs in CRLMs.
- To explore the therapeutic potential of targeting lncRNAs in CRLM.
Main Methods
- Analysis of lncRNA expression profiles in CRC tissues using TCGA database.
- Examination of lncRNA expression in normal, CRC, and CRLM tissues.
- In vitro and in vivo assays to determine the biological roles of LINC02257.
- Evaluation of LINC02257's therapeutic potential in a mouse CRLM model.
Main Results
- LINC02257 was highly expressed in metastatic CRC tissues and associated with poorer overall survival.
- LINC02257 promoted CRC cell growth, migration, and metastasis, while inhibiting apoptosis in vitro.
- LINC02257 enhanced liver metastasis in vivo by upregulating phosphorylated c-Jun N-terminal kinase (JNK).
Conclusions
- LINC02257 is crucial for CRC cell proliferation and metastasis via the LINC02257/JNK pathway.
- Targeting the LINC02257/JNK axis presents a promising therapeutic strategy for CRLM treatment.

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 gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...
