STX2 drives colorectal cancer proliferation via upregulation of EXOSC4.

Aims: To explore the biological function and mechanism of Syntaxin2 (STX2) in Colorectal cancer (CRC) proliferation.

Main Methods: A series of gain- and loss-of-function analysis were conducted the to explore the biological function of STX2 in CRC proliferation in vivo and in vitro. Western blot, Co-immunoprecipitation (Co-IP) and the functional analyses were taken to analyze the regulative role of STX2 on Exosome Complex 4 (EXOSC4) in CRC proliferation; Immunohistochemistry (IHC) and Real-time quantitative polymerase chain reaction (qPCR) were used to further verify the relationship between the expression of STX2 and EXOSC4 in human CRC samples.

targeting by miR-152-3p in Paclitaxel-resistant Breast Cancer.

Paclitaxel plays a pivotal role in the chemotherapy of breast cancer, but resistance to this drug is an important obstacle in the treatment. It is reported that microRNA-152-3p (miR-152-3p) is involved in tamoxifen resistance in breast cancer, but whether it is involved in paclitaxel resistance in breast cancer remains unknown. We examined the expression of miR-152-3p in breast cancer tissues and cells by qRT-PCR.

MiR-301a promotes embryonic stem cell differentiation to cardiomyocytes.

Recently, increasing evidence demonstrates diverse non-coding RNAs (ncRNAs) play critical roles in HDs. However, currently there lacks a systematic investigation of the association between HDs and ncRNAs.

RGC32 induces epithelial-mesenchymal transition by activating the Smad/Sip1 signaling pathway in CRC.

Response gene to complement 32 (RGC32) is a transcription factor that regulates the expression of multiple genes involved in cell growth, viability and tissue-specific differentiation. However, the role of RGC32 in tumorigenesis and tumor progression in colorectal cancer (CRC) has not been fully elucidated. Here, we showed that the expression of RGC32 was significantly up-regulated in human CRC tissues versus adjacent normal tissues.

DcR3 induces epithelial-mesenchymal transition through activation of the TGF-β3/SMAD signaling pathway in CRC.

Decoy receptor 3 (DcR3), a novel member of the tumor necrosis factor receptor (TNFR) family, was recently reported to be associated with tumorigenesis and metastasis. However, the role of DcR3 in human colorectal cancer (CRC) has not been fully elucidated. In this study, we found that DcR3 expression was significantly higher in human colorectal cancer tissues than in paired normal tissues, and that DcR3 expression was strongly correlated with tumor invasion, lymph node metastases and poor prognoses.

Long non-coding RNA MALAT1 increases AKAP-9 expression by promoting SRPK1-catalyzed SRSF1 phosphorylation in colorectal cancer cells.

Our earlier findings indicate that the long non-coding RNA MALAT1 promotes colorectal cancer (CRC) cell proliferation, invasion and metastasis in vitro and in vivo by increasing expression of AKAP-9. In the present study, we investigated the molecular mechanism by which MALAT1 enhances AKAP9 expression in CRC SW480 cells. We found that MALAT1 interacts with both SRPK1 and SRSF1.
