A peptide derived from chaperonin 60.1, IRL201104, inhibits LPS-induced acute lung inflammation.

Chaperonin 60.1 (Cpn60.1) is a protein derived from that has been shown, along with its peptide fragment IRL201104, to have beneficial effects in models of allergic inflammation.

Maternal Obesity in Mice Exacerbates the Allergic Inflammatory Response in the Airways of Male Offspring.

It was previously demonstrated that non-allergen-sensitized rodents born to mothers exposed to a high-fat diet (HFD) spontaneously develop lower respiratory compliance and higher respiratory resistance. In the present study, we sought to determine if mice born to mothers consuming HFD would exhibit changes in inflammatory response and lung remodeling when subjected to ovalbumin (OVA) sensitization/challenge in adult life. Mice born to dams consuming either HFD or standard chow had increased bronchoalveolar lavage (BAL) levels of IL-1β, IL-4, IL-5, IL-10, IL-13, TNF-α and TGF-β1 after challenge with OVA.

Sex differences in the influence of obesity on a murine model of allergic lung inflammation.

Background: Despite the overwhelming evidence showing the influence of sex or obesity in the development of respiratory diseases in humans and animals, the mechanisms by which these combined two factors influence allergic asthma are not well understood.

Objective: We have investigated the interaction between sex and weight gain in an experimental model of lung allergic inflammation induced by chicken egg ovalbumin (OVA) in mice.

Methods: Animals were fed a high-fat diet for 8 weeks and then sensitized and challenged with OVA.

Proteomic of goat milk whey and its bacteriostatic and antitumour potential.

Goat whey is normally discarded in the milk processing industry. However, several studies have addressed its biological properties and possible use in human or animal diet. The present study aimed to analysis the protein profile of goat whey to evaluate its possible oxidant, antioxidant, antibacterial, antitumour, and cytotoxic activities in vitro against human erythrocytes.

Lectin from seeds of a Brazilian lima bean variety (Phaseolus lunatus L. var. cascavel) presents antioxidant, antitumour and gastroprotective activities.

Lectins are proteins able to interact specifically and reversibly with carbohydrates. They are present in all living beings, particularly in legume seeds, which have many biological functions. The aim of this study was to isolate, characterize and verify antioxidant, anti-hemolytic, antitumor and gastroprotective activities in a lectin present in seeds of Phaseolus lunatus L.

Lectin of Abelmoschus esculentus (okra) promotes selective antitumor effects in human breast cancer cells.

The anti-tumor effects of a newly-discovered lectin, isolated from okra, Abelmoschus esculentus (AEL), were investigated in human breast cancer (MCF7) and skin fibroblast (CCD-1059 sk) cells. AEL induced significant cell growth inhibition (63 %) in MCF7 cells. The expression of pro-apoptotic caspase-3, caspase-9, and p21 genes was increased in MCF7 cells treated with AEL, compared to those treated with controls.
