Abstract

Echinacea spp. are popularly used as an herbal medicine or food supplement for enhancing the immune system and activating biological property in different tissues. In this study we show the biological effect of Echinacea augustifolia extract on cell viability and cell differentiation in mammary epithelial cell lines. These effects have been observed in two different cell line derived from mouse (HC11) and bovine (BME-UV). Echinacea extract enhanced cell liability from 100 to 1000 ng/ml in association with growth factors, epidermal growth factor (EGF) or insulin, but also without EGF (p<0.05) up to 37% vs. control. This effect may be modulated by MAPK and Akt activation that Echinacea extract treatment increased and/or by a reduction of caspase 3 activity, showed a dose-response decrease after Echinacea treatment. Finally Echinacea extract was able to increase (p<0.05) at 100 ng/ml beta-casein expression in association with PRL (5 microg/ml). These data demonstrate that Echinacea angustifolia extract can stimulate mammary epithelial cell physiology and may be considered a candidate to support mammary gland activity during a mammogenetic and lactogenetic state.

Caspases in Metabolic Diseases

Caspases, the family of cysteine proteases are involved in programmed cell death, but their role in metabolic diseases, inflammation and immunity has been of interested. Discover the latest research on caspases in metabolic diseases here.

Apoptotic Caspases

Apoptotic caspases belong to the protease enzyme family and are known to play an essential role in inflammation and programmed cell death. Here is the latest research.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
