T-ALL and T-lymphoblastic lymphoma

ABSTRACT: T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LL) and are often thought to represent a spectrum of a single disease. The malignant cells in T-ALL and T-LL are morphologically indistinguishable, and they share the expression of common cell surface antigens and cytogenetic characteristics. However, despite these similarities, differences in the predominant sites of disease in T-ALL and T-LL are observed. To determine if underlying biological distinctions may potentially contribute to some of these differences, we analyzed the global gene expression profiles of malignant T-cell precursors in ten T-ALL and nine T-LL using DNA arrays. Ten additional B-precursor ALL bone marrow samples, were used in a separate analysis. Keywords: ordered

Comprehensive Genomic Characterization of Five Canine Lymphoid Tumor Cell Lines

Project description:Background Leukemia/lymphoma cell lines have been critical in the investigation of the pathogenesis and therapy of hematological malignancies. While human LL cell lines have generally been found to recapitulate the primary tumors from which they were derived, appropriate characterization including cytogenetic and transcriptional assessment is crucial for assessing their clinical predictive value. Results In the following study, five canine LL cell lines, CLBL-1, Ema, TL-1 (Nody-1), UL-1, and 3132, were characterized using extensive immunophenotyping, karyotypic analysis, oligonucleotide array comparative genomic hybridization (oaCGH), and gene expression profiling. Genome-wide DNA copy number data from the cell lines were also directly compared with 299 primary canine round cell tumors to determine whether the cell lines represent primary tumors, and, if so, what subtype each most closely resembled. Discussion Based on integrated analyses, CLBL-1 was classified as B-cell lymphoma, Ema and TL-1 as T-cell lymphoma, and UL-1 as T-cell acute lymphoblastic leukemia. 3132, originally classified as a B-cell lymphoma, was reclassified as a histiocytic sarcoma based on characteristic cytogenomic properties. In combination, these data begin to elucidate the clinical predictive value of these cell lines which will enhance the appropriate selection of in vitro models for future studies of canine hematological malignancies.

Developmental and sexual dimorphic atlas of the prenatal mouse external genitalia at the single cell level

Project description:Before the onset of sexual differentiation, male and female external genitalia are morphologically indistinguishable. After the onset of sex-specific production of sex steroids by the gonads, the male and female external genitalia differentiate into either a penis or clitoris. Here we use single cell sequencing to investigate the similarities and differences of cell populations in the external genitalia during the critical sexual differentiation window in the mouse embryo. We found the male and female genitalia are largely similar in cell composition and gene expression at the bipotential stage of development. As sexual differentiation ensues, sex steroid-dependent and -independent differences in cell populations arise, leading to dimorphic establishment of the external genitalia.

Tandem mass tag labeling to characterize muscle-specific proteome change in beef during early postmortem

Project description:Bovine longissimus lumborum (LL) and psoas major (PM) muscles biopsy samples were collected from four carcasses (n = 4) at 45 min, 12 h, and 36 h postmortem from a commercial beef processing facility. Proteome profile variation between beef LL and PM during the early postmortem period were evaluated by tandem mass tag labeling containing ten different isobaric compounds.

Light effect on the hormonal and transcriptional status of winter and spring wheat plants during cold hardening

Project description:The effect of light during the development of freezing tolerance was studied in winter wheat (Triticum aestivum L. var. Mv Emese) and spring wheat variety Nadro. Ten-day-old plants were cold hardened at 5°C for 12 days either under normal (250 mmol m-2 s-1) or low light (20 mmol m-2 s-1) conditions. Samples of Emese (E) and Nadro (N) plants grown at 18°C under normal (NL) and low (LL) light fluences were compared to each other in a simple loop design and E-NL vs. E-LL; N-NL vs. N-LL; E-NL vs. NLL and E-LL vs. N-LL comparisons were made.
