LEUKEMIA, or blood cancer, symptoms are not always easily detected. The condition has several forms including acute myeloid leukaemia and chronic leukemia. You should look out for these five symptoms of the condition.

AbstractThe myelodysplastic syndromes, the chronic myeloproliferative neoplasms, and the acute myeloid leukemia are malignancies of the myeloid hematopoietic stem cells of the bone marrow. The diseases are characterized by a dysregulation of the immune system as both the cytokine milieu, immune phenotype, immune regulation, and expression of genes related to immune cell functions are deregulated. Several treatment strategies try to circumvent this deregulation, and several clinical and preclinical trials have shown promising results, albeit not in the same scale as chimeric antigen receptor T cells have had in the treatmen…

In cancer, the anomalous transcriptome includes deregulated expression of non-coding RNAs in conjunction with protein-coding mRNAs in human genome. The coding or non-coding RNA transc…

Publication date: September 2018Source: Human Pathology: Case Reports, Volume 13Author(s): Emily Feldpausch, Shilpa Sambidi, Durga Cherukuri, Jagmohan SidhuAbstractThe myeloproliferative neoplasms (MPNs) are chronic myeloid cancers (clonal hematopoietic disorders) that are characterized by the overproduction of terminally differentiated (mature) blood cells, and that may evolve into acute myeloid leukemia (AML). The literature indicates that three known driver mutations currently exist in BCR/ABL1-negative MPNs: JAK2, MPL and CALR. A small percentage of BCR/ABL1-negative MPN cases lack mutations in all three of these genes…

DIS3 (defective in sister chromatid joining) is the catalytic subunit of the exosome, a protein complex involved in the 3’–5′ degradation of RNAs. DIS3 is a highly conserved exoribonuclease, also known as Rrp44. Global sequencing studies have identified DIS3 as being mutated in a range of cancers, with a considerable incidence in multiple myeloma. In this work, we have identified two protein-coding isoforms of DIS3. Both isoforms are functionally relevant and result from alternative splicing. They differ from each other in the size of their N-terminal PIN (PilT N-terminal) domain, which has been shown to have endorib…

Mutations or other alterations in theRET gene have been implicated in a variety of malignancies – most commonly thyroid, but also chronic myelomonocytic leukemia, acute myeloid leukemia, and lung, breast, pancreatic, and colon cancers. Here we present a case of a gentlemen initially diagnosed with and treated for non-small cell lung adenocarcinoma. Genomic profiling of his tumor specimen rev ealed aRET point mutation with a known association with medullary thyroid cancer (MTC). Further pathological and molecular diagnostic evaluation confirmed a diagnosis of MTC, leading to a change in treatment from standard chemoth…

Conclusions. We aimed to shed light on ‘Sibling Rivalry’ in ceRNA partners from the perspective of statistical thermodynamics, identified major cross-talking tracks and ceRNAs influencing transcripts concerned in myeloid cancer systems. General significance. Insights into ceRNA-regulation will shed light on progression and prognosis of human Chronic and Acute Myeloid Leukemia.

Roche presented new data from studies in several blood cancers, including diffuse large B-cell lymphoma (DLBCL), chronic lymphocytic leukaemia (CLL) and acute myeloid leukaemia (AML) at the 2018 ASCO Annual Meeting, 1-5 June, in Chicago, IL, United States.

Abstract
DIS3 is the catalytic subunit of the exosome, a protein complex involved in the 3′ to 5′ degradation of RNAs. DIS3 is a highly conserved exoribonuclease, also known as Rrp44. Global sequencing studies have identified DIS3 as being mutated in a range of cancers, with a considerable incidence in multiple myeloma. In this work, we have identified two protein-coding isoforms of DIS3. Both isoforms are functionally relevant and result from alternative splicing. They differ from each other in the size of their N-terminal PIN domain, which has been shown to have endoribonuclease activity and tether DIS3 to the e…

CONCLUSIONS: Our analysis provided no convincing evidence for an increased risk of death from a range of hematolymphopoietic cancers in workers exposed to high or medium levels of ELF magnetic fields. However, we observed an increased risk of acute myeloid leukaemia in workers exposed to high levels for a longer duration. Observed risks are in line with meta-analysed previous reports on ELF-MF exposure and AML risk, with a summary relative risk of 1.21 (95%CI 1.08-1.37).
