Insulin-signalling is an important pathway in multiple cellular functions and organismal ageing across the taxa. A strong association of insulin-signalling with Parkinson's disease (PD) has been proposed but the exact nature of molecular events and genetic associations are yet to be understood. We employed transgenic strain harboring human α-synuclein::YFP transgene, towards studying the aggregation pattern of α-synuclein, a PD-associated endpoint, under human insulin (Huminsulin®) treatment and DAF-16/DAF-2 knockdown conditions, independently and in combination. The aggregation was increased when DAF-16 was knocked-down independently or alongwith a co-treatment of Human insulin (HumINS) and decreased when DAF-2 was knocked-down independently or alongwith a co-treatment of HumINS; whereas HumINS treatment per se, reduced the aggregation. Our results depicted that HumINS decreases α-synuclein aggregation via DAF-2/DAF-16 pathway by acting as an antagonist for DAF-2 receptor. Knockdown of reported DAF-2 agonist (INS-6) and antagonists (INS-17 and INS-18) also resulted in a similar effect on α-synuclein aggregation. Further by utilizing bioinformatics tools, we compared the differences between the binding sites of probable agonists and antagonists on DAF-2 including HumINS. Our results suggest that HumINS treatment and DAF-16 expression play a protective role against α-synuclein aggregation and its associated effects.

Mitochondria-targeted photodynamic therapy (PDT) circumvents the short lifetime and action radius limitation of reactive oxygen species (ROS) and greatly improves the anticancer PDT efficacy. However, current approaches require different molecular engineering strategies to separately improve ROS production and introduce mitochondria targeting ability, which involve tedious synthetic procedures. Herein, we report a facile one-step cationization strategy that simultaneously improves the ROS generation efficiency and introduces mitochondria targeting ability for enhanced PDT.

There is a concern on the safety of cosmetic ingredients and their endocrine-disrupting (ED) potential. Frequent use as well as the use of a diverse range of cosmetics pose a concern for a potential health risk via aggregate exposure to endocrine disrupting chemicals (EDCs). In this study, a list of ingredients available in cosmetic products that were recently introduced to the Dutch market was retrieved from the commercially accessible Mintel database and screened for the presence of EDCs.

Degradation during production and delivery is a significant bottleneck in developing biomolecular therapies. Protein cages, formed by engineered variants of lumazine synthase, present an effective strategy for the microbial production and isolation of labile biomolecular therapies. Genetic fusion of the target polypeptide to a cage component protomer ensures its efficient encapsulation within the cage during production in host bacterial cells, thereby protecting it from degradation.

The donor/acceptor (D/A) interfaces in bulk heterojunction (BHJ) organic solar cells (OSCs) critically govern exciton dissociation and molecular diffusion, determining both efficiency and stability. Herein, we design a double-cable conjugated polymer, SC-1F, to insert into a physically-blended D/A system to optimize the interface. We have found that SC-1F spontaneously segregates to the interface through favorable miscibility and heterogeneous nucleation with the acceptor.

Enhancing the energy conversion efficiency of fuel cells necessitates optimization of oxygen reduction reaction (ORR) under high-voltage conditions through improved Pt catalysis. This study introduces an electrocatalyst that uniformly anchors a high loading (40 wt%) of small Pt nanoparticles (3.2 nm) on a novel support: tellurium and nitrogen co-mediated graphitized mesoporous carbon (Te-N-GMC).
