The authors were requested to provide the raw data to prove the originality, but were unable to do so.

Antitumor effects of helenalin in doxorubicin-resistant leukemia cells are mediated via mitochondrial mediated apoptosis, loss of mitochondrial membrane potential, inhibition of cell migration and invasion and downregulation of PI3-kinase/AKT/m-TOR signalling pathway.

Purpose: The main purpose of the current study was to investigate the antitumor effects of helenalin - a plant derived sesquiterpene lactone, against doxorubicin-resistant acute myeloid leukemia HL60 cells, along with evaluating its effects on apoptosis induction, mitochondrial membrane potential (MMP), cell migration and inhibition and PI3K/AKT/M-TOR signalling pathway.

Methods: Antiproliferative effects were evaluated with CCK8 cell viability assay and colony formation assay. Cell apoptotic effects were studied by (acridine orange) AO/ethidium bromide (EB) staining assay.

HOXA11-AS promotes the migration and invasion of hepatocellular carcinoma cells by inhibiting miR-124 expression by binding to EZH2.

The objective of this study was to examine the function of the long non-coding RNA (lncRNA) HOXA11-AS in hepatocellular carcinoma (HCC). In total, samples from liver tumor and surrounding normal liver tissues were collected from 66 cases of HCC patients. Normal liver cell line HL-7702 and HCC cell lines HepG2, Hep3B, MHCC-97H and BEL7402 were used.

Lutein Inhibits Cell Growth and Activates Apoptosis via the PI3K/AKT/mTOR Signaling Pathway in A549 Human Non-Small-Cell Lung Cancer Cells.

Cancer, the uncontrolled growth of cells, is a major disease that threatens the worldwide population. Among all cancer types, lung cancer has the highest morbidity rate, with a survival rate of less than 5%. Various studies have focused on discovering a potent anticancer drug that will increase the survival rate of lung cancer patients.

Exploring the molecular pathogenesis associated with T-cell prolymphocytic leukemia based on a comprehensive bioinformatics analysis.

As a rare hematological malignancy, T-cell prolymphocytic leukemia (T-PLL) has a high mortality rate. However, the comprehensive mechanisms of the underlying pathogenesis of T-PLL are unknown. The purpose of the present study was to investigate the pathogenesis of T-PLL based on a comprehensive bioinformatics analysis.

Review of Rosai-Dorfman Disease: New Insights into the Pathogenesis of This Rare Disorder.

Rosai-Dorfman disease (RDD) is a rare histiocytosis typically with bilateral painless cervical lymphadenopathy. Laboratory data are nonspecific, and the presence of emperipolesis in large foamy S-100+ CD1a- histiocytes is the prominent histologic feature. The pathogenesis of RDD still remains elusive.

RNA-Seq analysis of non-small cell lung cancer in female never-smokers reveals candidate cancer-associated long non-coding RNAs.

We aimed to elucidate the potential mechanisms of long non-coding RNAs (lncRNAs) in the progression of non-small cell lung cancer (NSCLC). The microarray datasets of GSE37764, including 3 primary NSCLC tumors and 3 matched normal tissues isolated from 6 Korean female never-smokers, were downloaded from Gene Expression Omnibus database. The differentially expressed lncRNAs and mRNA in NSCLC samples were identified using NOISeq package.

Male accessory breast cancer successfully treated with endocrine therapy: A case report.

Male accessory breast cancer is an extremely rare tumor. Several risk factors have been identified, including genetic and hormonal abnormalities. Accessory breast carcinoma usually occurs under the axilla or in the inguinal region.

Langerhans cell histiocytosis with multisystem involvement in an infant: A case report.

Langerhans cell histiocytosis (LCH) is a proliferative disease of histiocyte-like cells, with a wide range of clinical presentations that vary from a solitary lesion to more severe multifocal or disseminated lesions. The disease can affect any age group; however, the peak incidence rate is in infants aged between 1 and 3 years-old. Diagnosis of LCH should be based on the synthetical analysis of clinical presentations, in addition to features of imaging and histopathology.

[Influence of gene transduction mediated by lentivirus vector on gene expression of human CD34+ cord blood cells].

Objective: To investigate the influence of gene transduction mediated by lentivirus vector on human CD34+ cord blood cell (CBCs) gene expression.

Methods: CD34+ cells were isolated and transduced with the third-generation self-inactivating ( SIN) lentiviral vector carrying green fluorescent protein (GFP). The total RNA from transduced cells was extracted and the differences of genotypes between the transduced and non-transduced CD34+ cells were determined with cDNA microarray analysis.
