Importantly, expression of FGF5 and phospho-HER2 correlated with a reduced pathologic complete response rate in patients with HER2 positive breast cancer treated with neoadjuvant trastuzumab which highlights the significant role of TAFs/FGF5 in HER2 breast cancer progression and resistance.
The expression of MTDH in tumor tissues of patients with HER2-positive locally advanced breast cancer was significantly elevated, which was related to the poor pathological features.High MTDH expression was closely correlated with poor prognosis of patients and was an important factor affecting tumor progression.
GPAA1 facilitates the expression of cancer-related GPI-anchored proteins and supplies a more robust platform-the lipid raft-to promote EGFR-ERBB2 dimerization, which further contributes to tumour growth and metastasis and to cancer progression.
Improving the outcome of patients with HER2-negative metastatic breast cancer experiencing tumour progression following first-line chemotherapy remains an urgent medical need.
Epidermal growth factor receptor (EGFR, also known as HER1) and HER2, prominent members of receptor tyrosine kinase (RTK) superfamily, have been reported as diagnostic or prognostic markers in tumor progression.
Several investigations reported that HER-2 (ErbB-2 receptor) and Epstein-Barr virus (EBV) are important etiological factors in human gastric cancer, where either oncogene/oncovirus alone can derive a major event of cancer progression and metastasis via epithelial-mesenchymal transition (EMT).
Although this serum biomarker will not replace the direct measurement of tumor HER2 status for diagnosis of early-stage tumors; it might be especially useful in metastatic disease for prognosis, as an indicator of cancer progression and of therapy response, particularly to anti-HER2 therapies.
The aim of this study was to evaluate the efficacy of adenovirus mediated HER2-siRNA in combination with cisplatin (Ad-HER2-siRNA+DDP) on treating HER2-positive ovarian cancer xenografts and explore the effectiveness of <sup>131</sup>I-Herceptin immunoSPECT imaging for monitoring the tumor's progression.
Human epidermal growth factor receptor 2 (HER2) is overexpressed in approximately 20% to 30% of breast cancers and various other types of cancers, which plays a vital role in the cancer progression.
Moreover, there is little information available on HER2 status role in tumor progression and metastasis in colorectal carcinoma (CRC) compared to other solid tumors.
Thus, with previous experimental evidences, the present review discussed the role of FoxOs in association with metastasis related molecules including cannabinoid receptor 1 (CNR1), Cdc25A/Cdk2, Src, serum and glucocorticoid inducible kinases (SGKs), CXCR4, E-cadherin, annexin A8 (ANXA8), Zinc finger E-box-binding homeobox 2 (ZEB2), human epidermal growth factor receptor 2 (HER2) and mRNAs such as miR-182, miR-135b, miR-499-5p, miR-1274a, miR-150, miR-34b/c and miR-622, subsequently analyzed the molecular mechanism of some natural compounds targeting FoxOs and finally suggested future research directions in cancer progression and metastasis.
Its contribution in dampening cancer progression is mainly attributed to the antibody-dependent cell-mediated cytotoxicity (ADCC) rather than HER2 blockade.
Sequential blockade of HER2 followed by JAGGED1 or NOTCH could be more effective than simultaneous blockade to prevent drug resistance and tumor progression.<i></i>.
Recently, we have shown that MUC13, which is highly expressed in pancreatic tumors, promotes tumor progression via modulation of HER2 receptor tyrosine kinase activity.
Resistance to human epidermal growth factor receptor-2 (HER2)-targeted therapies is common, and results in treatment failure and new tumor progression.
