BACKGROUND
Lichens produce specific secondary metabolites with different biological activity.
OBJECTIVE
This study investigated the cytotoxic effects of physodic acid, in addition to the total phenolic content and cytotoxic and antioxidant activity of acetone extract from Hypogymnia physodes (L.)
The acetone extract of Sclerocarya birrea (Anacardiaceae) possesses antiproliferative and apoptotic potential against human breast cancer cell lines (MCF-7).

Rabbits tolerant to human immunoglobulin G were used to raise antisera against the Raji cell-bound circulating immune complexes from human breast cancer sera. After solid-phase adsorption treatment with glutaraldehyde-cross-linked normal human plasma, acetone-extracted normal liver tissue powder,
Routine formaldehyde fixation irreversibly reduces immunoreactivity of Bcl-2 in the nuclear compartment of breast cancer cells, but not in the cytoplasm.

Bcl-2 and Bax belong to a family of proteins involved in apoptosis regulation and are believed to reside in the cellular cytoplasm. The authors recently reported interphase nuclear localization of both proteins after immunofluorescence staining of formaldehyde- and methanol-fixed human and rodent
Cross-reactivity of C219 anti-p170(mdr-1) antibody with p185(c-erbB2) in breast cancer cells: cautions on evaluating p170(mdr-1)

BACKGROUND
Increased expression of the multidrug resistance gene (MDR-1)-encoded P-glycoprotein (p170[mdr-1]) is a major cause of tumor cell multidrug resistance. p170(mdr-1) functions as a drug-efflux pump to reduce the cellular accumulation of specific drugs. MDA-MB-435 human breast cancer cells

There is available evidence supporting a positive association between alcohol intake and risk of breast cancer. However, there is limited information regarding possible mechanisms for this effect. Past studies from our laboratory suggest that acetaldehyde accumulation in mammary tissue after alcohol

Immunohistochemical analysis for products of vasopressin and oxytocin gene expression was performed on acetone-fixed tissues from 19 breast cancers representing a variety of tumor sub-types. Studies employed the avidin-biotin complex (ABC) immunohistochemical procedure and utilized rabbit polyclonal
