We observed that chick lens-fiber gap-junction-forming proteins, connexin (Cx) 45.6 and Cx56, were associated with an unknown protein, which was then identified as major intrinsic protein (MIP), also known as aquaporin-0 (AQP0), the most abundant membrane protein in lens fibers. A 1063 bp cDNA of chick MIP(AQP0) was identified that encodes a 262 amino acid protein with a predicted molecular wei...

Pathological bone resorption is a source of significant morbidity in diseases affecting the skeleton such as rheumatoid arthritis, periodontitis, and cancer metastasis to bone. Evidence indicates that elevated levels of inflammatory mediators such as IL-1, IL-6, and TNF-α play a role in this process by promoting the formation of bone-resorbing osteoclasts. Additionally, current studies have ide...

We have recently demonstrated that primary cultured rat pneumocytes produce macrophage inflammatory protein-2 (MIP-2) in response to lipopolysaccharide (LPS) stimulation. In this study, we found that brefeldin A, by blocking anterograde transport from the endoplasmic reticulum (ER) to the Golgi apparatus, decreased LPS-induced MIP-2 in the culture medium and increased its storage in cells. This...

Major intrinsic protein of lens fiber (MIP) is one of the proteins essential for maintaining lens transparency while also contributing to dominant cataracts in humans. The Nodai cataract (Nat) mice harbor a spontaneous mutation in Mip and develop early-onset nuclear cataracts. The Nat mutation is a c.631G>A mutation (MipNat), resulting in a glycine-to-arginine substitution (p.Gly211Arg) in the ...

The molecular and genetic events that contribute to the genesis and progression of cutaneous malignant melanoma are poorly understood, attributable in large part to the different genetic alterations accompanying tumorigenesis. Inhibitor of kinase 4a (INK4a) is often inactivated in families with hereditary melanoma. Loss of INK4a/alternate reading frame (ARF) in mice is associated with increased...

Macrophage inflammatory protein-1a (MIP-1a) can stimulate growth inhibitory and potent chemotactic functions in hematopoietic cells. To investigate whether the action of MIP-1a may be regulated at the cellular receptor level, we studied the expression and modulation of MIP-1a receptors on CD341 cells isolated from normal bone marrow (NBM), umbilical cord blood (CB), and leukapheresis products (...

PURPOSE Neutrophils are the most prominent cell type to migrate initially into the herpes simplex virus type 1 (HSV-1)-infected murine cornea. The role the C-X-C chemokines macrophage inflammatory protein (MIP)-2 and KC play in promoting this response was investigated. METHODS MIP-2 and KC were quantitated by enzyme-linked immunosorbent assay. Neutralization of endogenous MIP-2 and KC was ach...

BACKGROUND Peripheral nerves at the elbow region are prone to entrapment neuropathies and injuries. To make accurate assessment, clinicians need stereoscopic display of the nerves to observe them at all angles. OBJECTIVES To obtain a stereoscopic display of the peripheral nerves at the elbow region based on magnetic resonance (MR) diffusion tensor imaging (DTI) data using three post-processin...

This paper describes a new role for the cysteine-cysteine (CC) chemokines RANTES, MIP-1alpha, and MIP-1beta on human macrophage function, which is the induction of nitric oxide (NO)-mediated trypanocidal activity. In a previous report, we showed that RANTES, MIP-1alpha and MIP-1beta enhance Trypanosoma cruzi uptake and promote parasite killing by human macrophages (M. F. Lima, Y. Zhang, and F. ...

The main result of the present note states that it is consistent with the ZFC axioms of set theory (relying on Martin’s Maximum MM axiom), that every Asplund space of density character ω1 has a renorming with the Mazur intersection property. Combined with the previous result of Jiménez and Moreno (based upon the work of Kunen under the continuum hypothesis) we obtain that the MIP renormability ...
