Summary
This summary is machine-generated.T-box transcription factor 15 (TBX15) is elevated in glioma, promoting tumor growth and M2 macrophage polarization. Targeting the TBX15/TXNDC5 pathway, potentially with nanocarriers, offers a new therapeutic strategy for glioma.
Area Of Science
- Oncology
- Molecular Biology
- Cancer Research
Background
- T-box transcription factor 15 (TBX15) is implicated in various cancers, but its function in glioma remains largely unknown.
- Glioma is a primary brain tumor with significant unmet therapeutic needs.
Purpose Of The Study
- To investigate the expression and functional role of TBX15 in glioma.
- To elucidate the molecular mechanisms underlying TBX15's involvement in glioma progression.
- To evaluate the therapeutic potential of targeting the TBX15/TXNDC5 axis.
Main Methods
- Quantitative analysis of TBX15 expression in glioma tissues and normal brain.
- In vitro studies involving TBX15 silencing in glioma cells to assess proliferation, migration, and invasion.
- Macrophage recruitment and polarization assays.
- Western blotting and rescue experiments to identify downstream targets.
- In vivo studies using DNA origami nanocarriers loaded with sh-TBX15.
Main Results
- TBX15 expression is significantly upregulated in gliomas compared to normal tissues.
- High TBX15 levels correlate with poorer patient survival.
- TBX15 inhibition suppresses glioma cell proliferation, migration, and invasion.
- TBX15 silencing reduces macrophage recruitment and M2 polarization.
- Thioredoxin domain containing 5 (TXNDC5) was identified as a downstream target of TBX15, mediating its effects.
- DNA origami nanocarrier-mediated delivery of sh-TBX15 effectively suppressed glioma malignancy in vitro and in vivo.
Conclusions
- The TBX15/TXNDC5 signaling axis is crucial for glioma genesis and progression.
- TBX15 promotes glioma malignancy by influencing cell phenotypes and the tumor microenvironment.
- Targeting the TBX15/TXNDC5 pathway represents a promising therapeutic strategy for glioma treatment.

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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...
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...
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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...
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
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...
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...
