The Potential Effect of Oral Microbiota in the Prediction of Mucositis During Radiotherapy for Nasopharyngeal Carcinoma.

Background: Oral mucositis is probably the most debilitating complication that can arise in treating a patient with head and neck cancer. Little is known about the impacts of oral microbiota on the initiation and progression of mucositis.

Methods: Based on 16S rRNA gene sequencing, dynamic changes in oral bacterial profile as well as correlations between the severity of mucositis and bacterial shifts during radiotherapy were investigated.

Zinc finger E-box-binding homeobox 2 (ZEB2) regulated by miR-200b contributes to multi-drug resistance of small cell lung cancer.

Zinc finger E-box-binding homeobox 2 (ZEB2) was closely related to the oncogenesis, development and response to chemotherapy of cancer. However, its biological functions in small cell lung cancer (SCLC) remain unknown. The aim of this study is to investigate the roles of ZEB2 in chemoresistance of SCLC and its possible molecular mechanism.

MTA1 promotes nasopharyngeal carcinoma growth in vitro and in vivo.

Background: The prognostic value of metastasis-associated gene 1 (MTA1) in nasopharyngeal carcinoma (NPC) has been suggested. However, there is still no direct evidence that MTA1 promotes NPC growth in vivo. In this study, we aimed to investigate the function of MTA1 in the regulation of NPC cell proliferation and tumorigenesis in vitro and in vivo.

MTA1 promotes the invasion and migration of non-small cell lung cancer cells by downregulating miR-125b.

Background: The metastasis-associated gene 1 (MTA1) has been identified as one critical regulator of tumor metastasis. Previously, we identified miR-125b as a downregualted miRNA in non-small cell lung cancer (NSCLC) cell line upon MTA1 depletion. However, the role of miR-125b and MTA1 in the regulation of NSCLC metastasis remains unclear.

MTA1 contributes to actin cytoskeleton reorganization and metastasis of nasopharyngeal carcinoma by modulating Rho GTPases and Hedgehog signaling.

Nasopharyngeal carcinoma (NPC) is prone to appearing regional lymph node and distant metastasis. And its underlying mechanism is unclear. Recent study suggests that overexpression of metastasis-associated gene 1 (MTA1) was independently associated with poorer distant metastasis-free survival in NPC.
