Background: Lung function is dependent upon the precise regulation of the synthesis, storage, and catabolism of tissue and alveolar lipids.
Activation of sterol-response element-binding proteins (SREBP) in alveolar type II cells enhances lipogenesis causing pulmonary lipotoxicity.

View SamplesBBF2H7 (BBF2 human homolog on chromosome 7), an ER-resident basic leucine zipper transcription factor, is activated in response to ER stress and abundantly expresses in chondrocytes. While BBF2H7 is widely expressed in many tissues and organs, the most intense signals were detected in the proliferating zone of the cartilage. We compared gene expressions in primary cultured chondrocytes prepared from rib cartilage between WT and BBF2H7-/- mice at E18.5. Primary cultured chondrocytes were prepared from E18.5 rib cartilage of WT and BBF2H7-/- mice. Chondrocytes were isolated using 0.2% collagenase D (Roche) after adherent connective tissue was removed by 0.2% trypsin (Sigma) and collagenase pretreatment. Isolated chondrocytes were maintained in -MEM (Gibco) supplemented with 10% FCS and 50 g/mL ascorbic acid. Adenovirus vectors expressing the mouse p60 BBF2H7 (1-377 aa, BBF-N) were constructed with the AdenoX Expression system (Clontech), according to the manufacturers protocol. The cells were infected with adenoviruses 30 h before analysis.
Regulation of endoplasmic reticulum stress response by a BBF2H7-mediated Sec23a pathway is essential for chondrogenesis.
