Clinical assessment of miRNA-23b as a prognostic factor for various carcinomas: A systematic review and meta-analysis

Publication date: Available online 16 January 2020Source: Meta GeneAuthor(s): Ahmed Wadaa Allah, Mohammed Yahya, Khaled Saad Elsaeidy, Souad Alkanj, Khaled Hamam, Mohamed El-Saady, Mahmoud Ahmed EbadaAbstractObjectivesmiRNA-23b has been proposed to have a significant role in the prognosis of several types of tumors, despite the potential impact of its expression is still controversial. Innovative prognostic biomarkers for the prediction of cancer outcomes and the usage as therapeutic targets are warranted. We conducted this systematic review and meta-analysis to evaluate the associations between miRNA-23b expression and overall survival (OS) in various carcinomas.MethodsWe searched PubMed, Scopus, Web of Science, and Cochrane Central Register for relevant articles through May 2019. Data on the association of miRNA-23b expression and the OS was extracted and pooled in a meta-analysis model as a hazard ratio (HR) with the respective 95% confidence interval (CI). We used RevMan software version 5.2.ResultsTwelve eligible studies (n = 1589 patients) were included in our meta-analysis. The miRNA-23b downregulation was significantly associated with a more reduced OS (HR = 3.2, 95% CI [2.26 to 4.53], P

In this study, we compared the effects of L. barbarum fruit polysaccharide fractions on the growth of hepatoma cells (SMMC-7721 and HepG2), cervical cancer cells (HeLa), gastric carcinoma cells (SGC-7901), and human breast cancer cells (MCF-7). LBGP-I-3 showed stronger inhibitory effects on MCF-7 cells (cell viability of 48.96%) than SMMC-7721 (cell viability of 78.91%) and HeLa cells (cell viability of 55.94%), and had no effect on HepG2 and SGC-7901 cells. In addition, LBGP-I-3 had no inhibitory effect on normal liver cells (L02, cell viability of 115.58%). Investigation of the underlying mechanism suggested that LBGP-I-...

Rationale: Breast cancer is the most commonly diagnosed malignancies in females. The most common sites of metastasis are bone, lung, liver, and brain. Gastrointestinal and adrenal gland metastasis from breast cancer are rare. Simultaneous metastases are extremely rare. Therefore, it is critically important to choose proper examination and treatment since the rapid diagnosis and primary treatment can significantly affect the survival of patients. To the best of our knowledge, this was the first case of initial dual metastasis. Patient concerns: The patient had a history of left breast cancer, and she underwent left bre...

The SOX2OT gene is comprised of 10 exons and more than two transcription start sites. Dysregulation of SOX2OT is observed in various tumors, including lung cancer, gastric cancer, esophageal cancer, breast cancer, hepatocellular carcinoma, ovarian cancer, pancreatic ductal adenocarcinoma, laryngeal squamous cell carcinoma, cholangiocarcinoma, osteosarcoma, nasopharyngeal carc...

The imprinted gene is normally expressed from the maternal allele. However, this pattern of imprinting is dysregulated in several cancers leading to aberrant up-regulation of H19 in malignant tissues. Several studies have utilized this aberrant expression pattern to find specific biomarkers for detection of cancer in tumoral tissues or peripheral blood. Moreover, single nu...

She had previously undergone partial breast excision with axillary lymph node dissection for right breast cancer eleven years earlier and subtotal stomach-preserving pancreatoduodenectomy with Child's reconstruction for ampullary cancer ten years earlier. Gastrointestinal endoscopy showed a stricture due to a bulging submucosal tumor in the mid-thoracic esophagus. The tumo...

Metastatic invasive lobular carcinoma (mILC) may masquerade as primary diffuse gastric adenocarcinoma (PDGA) by demonstrating significant clinical and pathologic overlap. Accurate distinction is of therapeutic and prognostic significance. On the basis of anecdotal cases of mILC that lacked estrogen receptor and/or GATA3 expression, we analyzed the cytoarchitectural features of 28 mILC and 44 PDGA specimens obtained from women to assess features that would help in this distinction and prompt ancillary work-up. In addition to performing an interobserver agreement analysis among 3 pathologists, we also evaluated SATB2 express...
