Abstract

Acute myeloid leukemia (AML) is a common malignancy of the hematopoietic system. In bone marrow samples of AML patients, PDIA3 expression was higher than that in the samples of healthy controls. We aimed at exploring the effect of PDIA3 siRNA on proliferation, apoptosis, migration, and invasion of AML HL-60 and HEL cells. RT-PCR was performed to identify PDIA3 expression. Cell proliferation was assessed by MTT. Flow cytometry analysis and transwell were used to detect cell apoptosis, migration and invasion. Gene set enrich-ment analysis (GSEA) was employed to explore the PDIA 3-associated pathways in AML. Western blotting was used for protein expression detection. PDIA3 siRNA significantly inhibited the proliferation of AML cells at 24 and 48 h. PDIA3 siRNA notably enhanced the percentage of apoptotic cells. The migration and invasion abilities of HL-60 and HEL cells in the PDIA3 siRNA group were significantly suppressed compared with those in the control and siNC groups. GSEA of the Cancer Genome Atlas dataset showed that Kyoto Encyclopedia of Genes and Genomes oxidative phosphorylation and amino sugar and nucleotide sugar metabolism pathways could be correlated with PDIA3 expression; this was further confirmed in AML cells by...Continue Reading

Cell Migration in Cancer and Metastasis

Migration of cancer cells into surrounding tissue and the vasculature is an initial step in tumor metastasis. Discover the latest research on cell migration in cancer and metastasis here.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

AML: Role of LSD1 by CRISPR (Keystone)

Find the latest rersearrch on the ability of CRISPR-Cas9 mutagenesis to profile the interactions between lysine-specific histone demethylase 1 (LSD1) and chemical inhibitors in the context of acute myeloid leukemia (AML) here.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Acute Myeloid Leukaemia & RNA

Acute myeloid leukaemia (AML) is a common hematological type of cancer. As the population ages, there has been a rise in the frequency of AML. RNA expression has been used to see if there are different genetic profiles that exist within AML and whether these may underpin the variations in survival rates. Here is the latest research on AML and RNA.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.
