Otep, Sultan;Tseng, Yu-Cheng;Yomogita, Naomasa;Chang, Jia-Fu;Chueh, Chu-Chen;Michinobu, Tsuyoshi research published 《 Coil-rod-coil triblock copolymers synthesized by macromolecular clicking and their compatibilizer effects in all-polymer solar cells》, the research content is summarized as follows. Poly(diethynylthiophene) (PDET) synthesized via Hay coupling polycondensation retains terminal alkynes for tethering polystyrene (PS) blocks by a simple Cu-catalyzed azide-alkyne click (CuAAC) reaction. The successful synthesis of triblock copolymers was confirmed by ¹H NMR, FTIR, and GPC measurements. Optical and electrochem. properties of the PDET block were conserved in the triblock copolymers, as determined from the UV-vis absorption spectra and redox potentials. Surface topog. of the polymer films revealed the micrometer-scale features attributable to phase separation, which was supported by thermal analyses. The compatibilizer functions of PDET and triblock copolymer P1 were investigated and compared in all-polymer solar cells (all-PSCs). Addition of 1 wt% P1 was shown to result in an enhanced power conversion efficiency (PCE) from 5.90% to 6.24%, corresponding to a relative increase of ∼6%, whereas the addition of 1 wt% PDET decreased the resultant PCE. Notably, adding a proper compatibilizer helped reduce the device’s potential loss, as evidenced by the improved V_oc in the 1 wt% P1 device. Our results highlight the critical role of the coil segment in designing block copolymer-based compatibilizers for all-PSCs. Also, this study demonstrates a straightforward synthetic route for coil-rod-coil triblock copolymers that afford a compatibilizer function suitable for all-PSCs.

Musetti, Sara N.;Huang, Leaf research published 《 Tinagl1 Gene Therapy Suppresses Growth and Remodels the Microenvironment of Triple Negative Breast Cancer》, the research content is summarized as follows. Triple neg. breast cancer (TNBC) remains one of the most challenging subtypes of breast cancer to treat and is responsible for approx. 12% of breast cancer cases in the US per yr. In 2019, the protein Tinagl1 was identified as a key factor for improved prognoses in certain TNBC patients. While the intracellular mechanism of action has been thoroughly studied, little is known about the role of Tinagl1 in the tumor microenvironment. In this study, we developed a lipid nanoparticle-based gene therapy to directly target the expression of Tinagl1 in tumor cells for localized expression. Addnl., we sought to characterize the changes to the tumor microenvironment induced by Tinagl1 treatment, with the goal of informing future choices for combination therapies including Tinagl1. We found that Tinagl1 gene therapy was able to slow tumor growth from the first dose and that the effects held steady for nearly a week following the final dose. No toxicity was found with this treatment. Addnl., the use of Tinagl1 increases the tumor vasculature by 3-fold but does not increase the tumor permeability or risk of metastasis. However, the increase in vasculature arising from Tinagl1 therapy reduced the expression of Hif1a significantly (p < 0.01), which may decrease the risk of drug resistance.
