Circ_CLIP2 promotes glioma progression through targeting the miR-195-5p/HMGB3 axis.

Background: Circular RNA (circRNA) has been demonstrated to play key roles in regulating glioma progression. Understanding the regulatory mechanism of circRNA in glioma is vital to reveal the pathogenesis of glioma and develop novel therapeutic strategies. Therefore, our study focuses on the role and underlying mechanism of Circ_CLIP2 in glioma.

[Retracted] MicroRNA-375 inhibits glioma cell proliferation and migration by downregulating RWDD3 in vitro.

The authors of the above article drew to our attention that, in the above paper, they had identified three instances of data overlapping between data panels, suggesting that data purportedly showing results obtained under different experimental conditions had been derived from the same original source. Comparing among the data panels, two pairs of panels in Fig. 4B were shown to be overlapping, and a further pair of panels showed overlapping data in Fig.

The authors of the above article drew to our attention that they had identified three instances of data overlapping between data panels, suggesting that data purportedly showing results obtained under different experimental conditions had been derived from the same original source. Comparing between the two figures, two pairs of panels in Fig. 4B (the Mimics control and blank experiments for the U87 and U251 cell lines) were shown to be overlapping, and a further pair of panels showed overlapping data in Fig.

MicroRNA-375 inhibits glioma cell proliferation and migration by downregulating RWDD3 in vitro.

Derived from brain glial cells, gliomas are currently the most common primary tumours in the central nervous system and are characterised by a high recurrence rate and poor prognosis. RWDD3 (RWD domain-containing sumoylation enhancer, also termed RSUME), which can be induced by cellular stress, such as CoCl2, heat shock and hypoxia, may play a crucial role in tumour angiogenesis, growth and metastasis. MicroRNAs (miRNAs) have been demonstrated to act as negative regulators of post-transcriptional gene expression and are involved in tumour growth and metastasis.

Lentivirus‑mediated knockdown of chondroitin polymerizing factor inhibits glioma cell growth in vitro.

Glioma is the most common primary tumor in the central nervous system, characterized by rapid progression, aggressive behavior, frequent recurrence and poor prognosis. In the present study we demonstrated that chondroitin polymerizing factor (CHPF) is highly expressed in human glioma tissues and 4 glioma cell lines. To explore the role of CHPF in glioma, a lentiviral vector expressing CHPF shRNA was constructed and transfected into the glioma U251 cells, which stably downregulated the expression levels of the CHPF gene in U251 cells in vitro.

SNORD47, a box C/D snoRNA, suppresses tumorigenesis in glioblastoma.

SNORD47 is a member of the C/D box small nucleolar RNAs, which have been implicated in cancer development. We intended to investigate the therapeutic potential of SNORD47 in glioma. We found that the expression of SNORD47 was downregulated in glioma tissues samples and inversely associated with advanced tumor stage (WHO grade IV).

Over-expression of LRIG1 suppresses biological function of pituitary adenoma via attenuation of PI3K/AKT and Ras/Raf/ERK pathways in vivo and in vitro.

Pituitary adenomas (PAs) are well known as a common intracranial benign tumor, and a portion of PAs are refractory to current therapeutic methods. ErbB receptors family signaling pathway regulates the expression of PAs activation associated gene. Inhibition of epidermal growth factor receptor (EGFR) can inhibit proliferation of PAs.
