CircCRIM1 promotes the translation of HIF-1α protein through its interaction with PTBP3 and enhances malignant progression and angiogenesis in glioblastoma.

Glioblastoma (GBM) is the most aggressive type of primary intracranial tumor. Circular RNAs (circRNAs) are closely related to the malignant progression of GBM. Elevated levels of Circular RNA hsa_circ_0002346 (circCRIM1) significantly correlate with tumor growth, metastasis, and poor prognosis, suggesting its potential as a biomarker for cancer diagnosis and treatment response.

miR-3154 promotes glioblastoma proliferation and metastasis via targeting TP53INP1.

Glioblastomas (GBM) are most common types of primary brain tumors and miRNAs play an important role in pathogenesis of glioblastomas. Here, we reported a new miRNA, miR-3154, which regulates glioblastoma proliferation and metastasis. miR-3154 was elevated in glioblastoma tissue and cell lines, and its elevation was associated with grade of glioblastomas.

Dioscin decreases M2 polarization via inhibiting a positive feedback loop between RBM47 and NF-κB in glioma.

Background: The role of the glioblastoma (GBM) microenvironment is pivotal in the development of gliomas. Discovering drugs that can traverse the blood-brain barrier and modulate the tumor microenvironment is crucial for the treatment of GBM. Dioscin, a steroidal saponin derived from various kinds of plants and herbs known to penetrate the blood-brain barrier, has shown its powerful anti-tumor activity.

Lysine-40 succinylation of TAGLN2 induces glioma angiogenesis and tumor growth through regulating TMSB4X.

Protein lysine succinylation (K) represents an important regulatory mechanism of tumor development. In this work, the difference of protein K between HCMEC/D3 co-cultured with U87 (glioma endothelia cells, GEC) and without U87 (normal endothelia cells, NEC) was investigated using TMT labeling and affinity enrichment followed by high-resolution LC-MS/MS analysis. Interestingly, TAGLN2 was highly succinylated at K40 in GEC (15.

Lnc00462717 regulates the permeability of the blood-brain tumor barrier through interaction with PTBP1 to inhibit the miR-186-5p/Occludin signaling pathway.

Blood-brain tumor barrier (BTB) severely restricts the efficient delivery of chemotherapeutic drugs into brain tumor tissue, which is a critical obstacle for glioma treatment. Recently, long noncoding RNAs (lncRNAs) have shown as regulation factors of numerous biological processes. In this study, we identified that Lnc00462717 was upregulated in glioma endothelial cells (GECs), and that knockdown of Lnc00462717 significantly increased the BTB permeability.

Long non-coding RNA SNHG12promotes the proliferation and migration of glioma cells by binding to HuR.

Long non-coding RNAs (lncRNAs) play important roles in biological processes and provide a novel approach with which to understand the molecular mechanisms responsible for glioma. Previous studies have demonstrated that lncRNA small nucleolar RNA host gene 12 (SNHG12) is involved in cell growth and migration. However, the accurate expression pattern of SNHG12 in glioma and the possible associations between this pattern and the clinicopathological characteristics of glioma cohorts are not yet known.
