Advanced Science, Volume 13, Issue 34, 19 June 2026.ABSTRACT Triple‐negative breast cancer (TNBC) exhibits addiction to chronic endoplasmic reticulum (ER) stress, which sustains an aggressive metastatic phenotype through activation of the unfolded protein response (UPR). Here, we identify a previously unrecognized “ER‐stress addiction” axis in which the Hippo pathway effector TEAD4 directly ...

Chromatography of Acidic Polysaccharides on Deae-Cellulose [PDF]
Australian Journal of Biological Sciences, 1962 The chromatography of polysaccharides on resinous ion-exchangers has been reported by Steiner, Neukom, and Deuel (1958). Neukom et al. (1960) later reported the chromatography of a variety of wheat and sugar-beet polysaccharides on DEAEcellulose. Only "neutral" polysaccharides could be eluted at pH 6-8 by increasing buffer and salt concentrations; acid
