Studies on the System Regulating Proton Movement across the Chloroplast Envelope : Effects of ATPase Inhibitors, Mg, and an Amine Anesthetic on Stromal pH and Photosynthesis.

Plant physiology

Peters JS, Berkowitz GA.
PMID: 16668116
Plant Physiol. 1991 Apr;95(4):1229-36. doi: 10.1104/pp.95.4.1229.

Studies were undertaken to further characterize the spinach (Spinacea oleracea) chloroplast envelope system, which facilitates H(+) movement into and out of the stroma, and, hence, modulates photosynthetic activity by regulating stromal pH. It was demonstrated that high envelope-bound Mg(2+)...

Stereochemical survey of digitoxin monosaccharides: new anticancer analogues with enhanced apoptotic activity and growth inhibitory effect on human non-small cell lung cancer cell.

ACS medicinal chemistry letters

Wang HY, Xin W, Zhou M, Stueckle TA, Rojanasakul Y, O'Doherty GA.
PMID: 21643465
ACS Med Chem Lett. 2011 Jan 13;2(1):73-78. doi: 10.1021/ml100219d.

A stereochemically diverse array of monosaccharide analogues of the trisaccharide based cardiac glycoside natural product digitoxin has been synthesized using a de novo asymmetric approach. The analogues were tested for cytotoxicity against the NCI panel of 60 human cancer...

Cryopreservation of Digitalis lanata cell cultures.

Planta medica

Diettrich B, Popov AS, Pfeiffer B, Neumann D, Butenko R, Luckner M.
PMID: 17396948
Planta Med. 1982 Oct;46(2):82-7. doi: 10.1055/s-2007-970026.

Suspension cultures of Digitalis lanata strain I were grown in a medium containing 3% mannitol. For cryopreservation cell suspensions were treated with a mixture of sucrose-glycerol (20%/20 V%), cooled slowly (about 1 degrees C/min) till -100 degrees C and...

Digitoxin induces apoptosis in cancer cells by inhibiting nuclear factor of activated T-cells-driven c-MYC expression.

Journal of carcinogenesis

Yang QF, Dalgard CL, Eidelman O, Jozwik C, Pollard BS, Srivastava M, Pollard HB.

J Carcinog. 2013 May 20;12:8. doi: 10.4103/1477-3163.112268. Print 2013.

BACKGROUND: Cardiac glycosides such as digitoxin have been shown to directly cause apoptotic death of cancer cells both in vitro, and in vivo. However, the mechanism connecting cardiac glycoside action to apoptosis is not known. It has been reported...

Seasonal and intraplant variation of cardenolide content in the California milkweed,Asclepias eriocarpa, and implications for plant defense.

Journal of chemical ecology

Nelson CJ, Seiber JN, Brower LP.
PMID: 24420825
J Chem Ecol. 1981 Nov;7(6):981-1010. doi: 10.1007/BF00987622.

Root, stem, leaf, and latex samples ofAsclepias eriocarpa collected from three plots in one population at 12 monthly intervals were assayed for total cardenolide content by spectroassay and for individual cardenolides by thin-layer chromatography. From May to September mean...

Digitoxin Inhibits Epithelial-to-Mesenchymal-Transition in Hereditary Castration Resistant Prostate Cancer.

Frontiers in oncology

Pollard BS, Suckow MA, Wolter WR, Starr JM, Eidelman O, Dalgard CL, Kumar P, Battacharyya S, Srivastava M, Biswas R, Wilkerson MD, Zhang X, Yang Q, Pollard HB.

Front Oncol. 2019 Aug 02;9:630. doi: 10.3389/fonc.2019.00630. eCollection 2019.

Castration Resistant Prostate Cancer (CRPC) is thought to be driven by a collaborative mechanism between TNFα/NFκB and TGFβ signaling, leading to inflammation, Epithelial-to-Mesenchymal-Transition (EMT), and metastasis. Initially, TGFβ is a tumor suppressor, but in advanced metastatic disease it switches...

Cytotoxic effect of carbohydrate derivatives of digitoxigenin involves modulation of plasma membrane Ca.

Eliminating primary tumor ("roots") and inhibiting associated-circulating tumor cells (associated-CTCs, "seeds") are vital issues that need to be urgently addressed in cancer therapy. Associated-CTCs, which include single CTCs, CTC clusters, and CTC-neutrophil clusters, are essential executors in metastasis and...
