UTSA Researchers Create Leukemia Proteome Atlases to Assist in Leukemia Research and Personalized Medicine Treatments


This new atlas of leukemia proteomes may prove useful for medical laboratories and pathologists providing diagnostic and prognostic services to physicians treating leukemia patients Clinical pathology laboratories, hematopathologists, and medical technologists (aka, medical laboratory scientists) have a new tool that aids in leukemia research and helps hematologists and other medical practitioners treat patients with acute […]

Conclusion and Perspectives
Being exquisitely regulated by “writers,” “erasers,” and “readers,” additional repelled proteins or miRNAs, m6A modification relates to nearly any step of mRNA metabolism, as well as ncRNA processing and circRNA translation. There is compelling evidence suggesting that m6A modification is especially critical in a variety of pathologic and physiologic immune responses including T cell homeostasis and differentiation, inflammation, and type I interferon production. Further results have indicated that aberrancies of interferon and Th17 frequencies in systemic lu…

Epidemiological studies have repeatedly helped identify definitive triggers for several diseases. As highlighted in this perspective report, previous studies strongly argue for the interplay between intrinsic factors and putative preventable extrinsic triggers/promoters for CTCL. Given the evidence of geographical regional clustering of CTCL patients, CTCL occurrence in unrelated family members and recent evidence implicating S. aureus in the pathogenesis/progression of CTCL, more research is needed to decipher the precise mechanism by which specific environmental exposures may be driving the pathogenesis of t…

Suppressor of cytokine signaling 1 is an essential molecule for maintaining immune homeostasis and subverting inflammation. Disorders arising from excess inflammation or SOCS1 deficiency can be potentially treated with SOCS1 mimetics (Ahmed et al., 2015). While SOCS1 has promising potential in many disorders, it should be noted that new targets and actions of SOCS1 are still being discovered and not all the effects of this protein are beneficial in autoimmune diseases and cancer. For instance, SOCS1 degrades IRS1 and IRS2, required for insulin signaling, via the SOCS Box domain, thus, limiting its potential in …

Purpose of review
Disease relapse remains the major cause of treatment failure in adults with acute myeloid leukemia (AML) in first complete remission (CR1) treated with intensive chemotherapy alone. Allogeneic stem cell transplantation (allo-SCT) reduces the risk of disease recurrence, and thus the advent of reduced intensity-conditioning regimens coupled with increased donor availability has increased the deliverability of potentially curative transplant therapy in AML. However, allo-SCT remains associated with significant additional morbidity and mortality, and it is therefore important to identify patients whose outc…

Myelodysplastic syndrome (MDS) is a heterogeneous hematological malignancy, characterized by cytopenia and accompanied by a risk of transformation into acute myeloid leukemia (AML). Epidemiological studies for decades have shown association between autoimmune diseases (AIDs) and MDS. Specifically, patients with antecedent AIDs tends to have an increased risk of developing MDS, and these patients display different clinical characteristics and outcomes. Importantly, immune dysregulation has been the common driving force between MDS and AIDs pathogenesis.

The PURA gene encodes Pur-alpha, a 322 amino acid protein with repeated nucleic acid binding domains that are highly conserved from bacteria through humans. PUR genes with a single copy of this domain have been detected so far in spirochetes and bacteroides. Lower eukaryotes possess one copy of the PUR gene, whereas chordates possess 1-4 PUR family members. Human PUR genes encode Pur-alpha (Pura), Pur-beta (Purb) and two forms of Pur-gamma (Purg). Pur-alpha is a protein that binds specific DNA and RNA sequence elements. Human PURA, located at chromosome band 5q31, is under complex control of three promote…

The ability to assess antileukemic drug activity on primary patient samples is a powerful tool in determining potential drug targets and selection of therapeutic agents with biological and functional rationale. We previously established small molecule inhibitor screens for use on freshly isolated leukemia cells for this purpose. Here we describe a method that produces functional small molecule inhibitor screening results using cryopreserved primary acute myeloid leukemia cells. This method was established to take advantage of biorepositories containing archival material, such as those established by the Children’s On…

CONCLUSIONS: In difficult cases of MDS or MPN, NGS facilitates diagnosis by detection of gene mutations to confirm clonality, and AMLs evolving from MDS or MPN carry frequent mutations in spliceosomal genes.

In this study, we screened the efficacy of δ-T against six cell lines representing a wide spectrum of hematologic malignancies: Jurkat (acute T-cell leukemia), K-562 (chronic myeloid leukemia), KG-1 [acute myeloid leukemia (AML)], THP-1 (acute monocytic leukemia), TOM-1 (acute lymphoblastic leukemia), and UMCL01-101 (AIDS-associated diffuse large B-cell lymphoma). Interestingly, the AML cell line KG-1 was the only one to be significantly affected at concentrations of δ-T as low as 20 µM. The antileukemic activity of δ-T in AML was verified in a set of primary cells collected from patients newly…
