Angiostatin inhibits angiogenesis by binding to endothelial cells (ECs) lining the vasculature of growing tumors. These cells are in a dynamic state during angiogenesis and are thus not firmly attached to the extracellular matrix. This makes them mor

Tumor cells in vivo often exist in an ischemic microenvironment that would compromise the growth of normal cells. To minimize intracellular acidification under these conditions, these cells are thought to upregulate H+ transport mechanisms and/or slo

Cells which have been adapted to growth at low extracellular pH (pHe) typically develop both an upregulation of steady state intracellular pH (pHi) and an ability to develop thermotolerance to 42 degrees C hyperthermia. These properties were acquired

Intracellular pH (pHi) homeostasis is crucial to cell survival. Cells that are chronically exposed to a low pH environment must adapt their hydrogen ion extrusion mechanisms to maintain their pHi in the physiologic range. An important component of th

Amifostine, a chemo- and radioprotective agent developed as adjunctive therapy for malignancies, induces hypotension after approximately 20% of patient administrations. This study examines the molecular mechanisms underlying hypotension induced by am

As an in vitro model for the low extracellular pH (pHe) which has frequently been observed in tumors, cell lines have been grown in a low-pH medium in order to allow cell adaptation to that milieu. Two Chinese hamster cell lines [Chinese hamster ovar

Fluorescent measurements of intracellular H(+) and Na(+) are improved by using whole spectra of the fluorescent indicators BCECF and SBFI, respectively. The extra data in whole spectra enable both an accurate calibration and a ready detection of arti

Peroxidase-conjugated anti-surface immunoglobulin (sIg) was used quantitatively to monitor endocytosis of crosslinked sIg on murine B lymphocytes. The role of biochemical second messengers in the initiation of endocytosis was assessed by employing se

The influence of the protein matrix on the reactivity of external molecules with a species buried within the protein interior is considered in two general ways: (1) there may be structural fluctuations that allow for the diffusive penetration of the

Carboxy-SNARF-1 is an emission-changing, pH-sensitive probe for measurements of intracellular pH. However, the protonated and deprotonated forms of the dye interact differently with intracellular constituents, and this imposes new requirements on the
