Abstract
PNU-159682 is a highly potent secondary metabolite of nemorubicin belonging to the anthracycline class of natural products. Due to its extremely high potency and only partially understood mechanism of action, it was deemed an interesting starting point for the development of a new suite of linker drugs for antibody drug conjugates (ADCs). Structure activity relationships were explored on the small molecule which led to six linker drugs being developed for conjugation to antibodies. Herein we describe the synthesis of novel PNU-159682 derivatives and the subsequent linker drugs as well as the corresponding biological evaluations of the small molecules and ADCs.

Abstract
Previously, Aznar et al., showed that Daple/CCDC88C enables Wnt receptors to transactivate trimeric G-proteins during non-canonical Wnt signaling via a novel G-protein binding and activating (GBA) motif. By doing so, Daple serves two opposing roles; earlier during oncogenesis it suppresses neoplastic transformation and tumor growth, but later it triggers epithelial-to-mesenchymal-transition (EMT). We have identified and characterized two isoforms of the human Daple gene. While both isoforms cooperatively suppress tumor growth via their GBA motif, only the full-length transcript triggers EMT and invasion. Both isoforms are suppressed during colon cancer progression, and their reduced expression carries additive prognostic significance. These findings provide insights into the opposing roles of Daple during cancer progression and define the G-protein regulatory GBA motif as one of the minimal modules essential for Daple’s role as a tumor suppressor.

Abstract
Telocytes, a recently discovered type of interstitial cells, have a very distinctive morphology - the small cell body with long extensions, named telopodes. In our review, apart from introducing general aspects of telocytes, we focus on properties, functions and future potential of those cells in cardiovascular system. However, physiological functions of telocytes in cardiovascular system are still regarded as quite enigmatic. Previous studies claim that they play a role in organogenesis and regeneration, bioelectrical signalling, mechanoelectrical coupling, anti-oxidative protection, angiogenesis and regulation of blood flow. As well, they are presumably connected with the presence of blood-myocardium barrier and proper organisation of extracellular matrix. Moreover, there exists a significant link between the quantity of telocytes in tissue and numerous cardiovascular diseases such as: myocardial infarction, cardiomyopathies, systemic sclerosis, heart failure, atrial fibrillation, isolated atrial amyloidosis, myxomatous valve degeneration and hyperplastic consequences of vascular injury. Thanks to their unique properties, telocytes might be a breakthrough in treatment of cardiovascular diseases, as they may be effective in reversing effects of myocardial infarction. Telocytes also may play a major role in tissue engineering - they might be the key factor in creating stable and efficient vascular network in larger synthetic tissues or organs (Tab. 1, Fig. 3, Ref. 53).
