The Clinical Implications of Human Telomerase Reverse Transcriptase Expression in Grade and Prognosis of Gliomas: a Systematic Review and Meta-analysis.

Human telomerase reverse transcriptase (hTERT), a ribonucleoprotein, is reported as an important complex, which is required for stability of DNA molecular structure at the rear of the chromosome. Until now, hTERT has been linked to cell immortalization and tumorigenesis. A couple of articles have been published about the telomerase function in the gliomas; however, these results are conflicting in some degree.

Crk-like adapter protein regulates CCL19/CCR7-mediated epithelial-to-mesenchymal transition via ERK signaling pathway in epithelial ovarian carcinomas.

Recent studies have suggested that Crk-like adapter protein (CrkL) and epithelial-to-mesenchymal transition (EMT) induced by CCL19/CCR7 play an important role in ovarian epithelial carcinogenesis. However, the regulatory mechanisms of CrkL on the CCL19/CCR7 signaling pathways in epithelial ovarian carcinomas (EOC) are not well characterized. Here, CCR7 and CrkL proteins were tested in 30 EOC tissues and cell lines.

Crk-like adapter protein is required for TGF-β-induced AKT and ERK-signaling pathway in epithelial ovarian carcinomas.

Crk-like adapter protein (CrkL) was identified as an important biomarker in epithelial ovarian carcinomas. At the same time, the transforming growth factor β (TGF-β) pathway plays a key role in oncogenesis of advanced cancers. However, more detailed regulation mechanisms are still unclear.

The clinical implications of Crk-like adaptor protein expression in papillary thyroid microcarcinoma.

Papillary thyroid microcarcinoma (PMC) is the most common subtype of thyroid carcinomas with satisfactory prognosis. Crk-like (CrkL) adaptor protein was identified in the development of many carcinomas. However, the clinical implications of CrkL protein in PMC were still unknown.

The essential roles of CCR7 in epithelial-to-mesenchymal transition induced by hypoxia in epithelial ovarian carcinomas.

The chemokine receptor CCR7 and its ligands CCL19/21 mediate the tumor mobility, invasion, and metastasis (Wu et al. Curr Pharm Des. 15:742-57, 2009).

The correlation of bone morphogenetic protein 2 with poor prognosis in glioma patients.

Glioma is the most common type of human intracranial cancers and has poor prognosis. Bone morphogenetic protein 2 (BMP2) plays important roles in cancer cell signalings (Vecht et al. Oncologist 19:751-9, 2014).

Cell surface nucleolin is crucial in the activation of the CXCL12/CXCR4 signaling pathway.

Recently, CXCL12-CXCR4 has been focused on therapeutic strategies for papillary thyroid carcinoma (PTC) and other cancers. At the same time, cell surface nucleolin is also over-expressed in PTC and others. Interestingly, a few reports suggest that either CXCR4 or cell surface nucleolin is a co-receptor for HIV-1 entry into CD4+ T cells, which indicates that there is a relationship between CXCR4 and nucleolin.
