Description
BALB/c mice are susceptible to proteoglycan (PG) aggrecan-induced arthritis (PGIA), a murine model of rheumatoid arthritis (Glant,T.T. and Mikecz,K., Proteoglycan aggrecan-induced arthritis. A murine autoimmune model of rheumatoid arthritis. Methods Mol.Med. 2004. 102: 313-338.). However, there are marked differences among BALB/c colonies (maintained by different vendors at different locations) in PGIA onset and severity, which could be the result of subtle variations in their genetic background.
Publication Title
BALB/c mice genetically susceptible to proteoglycan-induced arthritis and spondylitis show colony-dependent differences in disease penetrance.

Description
Mammalian microRNAs (miRNAs) are emerging as key regulators of the development and function of the immune system. Here, we report a strong but transient induction of miR-155 in mouse bone marrow after injection of bacterial lipopolysaccharide (LPS) correlated with granulocyte/monocyte (GM) expansion. Demonstrating the sufficiency of miR-155 to drive GM expansion, enforced expression in mouse bone marrow cells caused GM proliferation in a manner reminiscent of LPS treatment. However, the mir-155-induced GM populations displayed pathological features characteristic of myeloid neoplasia. Extending possible relevance to human disease, miR-155 was overexpressed in the bone marrow of patients with acute myeloid leukemia (AML). Furthermore, miR-155 repressed a subset of genes implicated in hematopoietic development and disease. These data implicate miR-155 as a contributor to physiological GM expansion during inflammation and to certain pathological features associated with AML, emphasizing the importance of proper miR-155 regulation in developing myeloid cells during times of inflammatory stress.

Description
The traditional view of hematopoiesis has been that all the cells of the peripheral blood are the progeny of a unitary homogeneous pool of hematopoietic stem cells (HSCs). Recent evidence suggests that the hematopoietic system is actually maintained by a consortium of HSC subtypes with distinct functional characteristics. We show here that myeloid-biased HSCs (My-HSCs) and lymphoid-biased (Ly-HSCs) can be purified according to their capacity for Hoechst dye efflux in combination with canonical HSC markers.

Distinct hematopoietic stem cell subtypes are differentially regulated by TGF-beta1.

Description
Cells undergoing malignant transformation often shift their cellular metabolism from primarily oxidative phosphorylation to aerobic glycolysis (the Warburg effect). Energy restriction-mimetic agents (ERMAs), such as 2-deoxyglucose and resveratrol, that target this shift in cellular metabolism have been effective in inhibiting cancer cell growth in vitro, and xenograft tumor growth in vivo.

Description
Prophase I of meiosis involves dynamic chromosome segregation processes including synapsis, meiotic recombination, and cohesion. Genetic defects in genes participating in these processes consistently cause reproduction failure in mice. To identify candidate genes responsible for infertility or recurrent pregnancy loss in humans, we performed expression profiling of male and female gonads of mice undergoing meiotic prophase I.

Screening of genes involved in chromosome segregation during meiosis I: in vitro gene transfer to mouse fetal oocytes.
