Background: Cell culture studies play an important role in addressing fundamental scientific questions. However, inadequate reporting of these studies results in a lack of transparency and reproducibility. Recognizing the need for improvement, several ongoing efforts, such as CRIS guidelines and the ICLAC checklist, are focused on enhancing best practices for in vitro studies.

The zinc finger protein 32 (ZNF32) has been associated with high expression in various cancers, underscoring its significant function in both cancer biology and immune response. To further elucidate the biological role of ZNF32 and identify potential immunotherapy targets in cancer, we conducted an in-depth analysis of ZNF32. We comprehensively investigated the expression of ZNF32 across tumors using diverse databases, including TCGA, CCLE, TIMER2.

Iron-sulfur clusters are essential metallocofactors synthesized by multiprotein machineries via an unclear multistep process. Here we report a step-by-step dissection of the [2Fe-2S] cluster assembly process by the Escherichia coli iron-sulfur cluster (ISC) assembly machinery using an in vitro reconstituted system and a combination of biochemical and spectroscopic techniques. We show that this process is initiated by iron binding to the scaffold protein IscU, which triggers persulfide insertion by the cysteine desulfurase IscS upon the formation of a complex with IscU.

Adenosine Deaminases Acting on RNA (ADARs) convert adenosine to inosine in duplex RNA, and through the delivery of guide RNAs, can be directed to edit specific adenosine sites. As ADARs are endogenously expressed in humans, their editing capacities hold therapeutic potential and allow us to target disease-relevant sequences in RNA through the rationale design of guide RNAs. However, current design principles are not suitable for difficult-to-edit target sites, posing challenges to unlocking the full therapeutic potential of this approach.

The recent development of modular universal chimeric antigen receptor (CAR) T-cell platforms that use bifunctional adaptor intermediates to redirect engineered T-cell effector function has greatly expanded the capabilities of adoptive T-cell therapy, enabling safer and more comprehensive cancer treatment. However, universal CAR receptor systems rely on unstable transient recognition of tag-coupled intermediates for T-cell activation, and the array of targeting intermediates has been limited to antibodies and small molecules. Addressing these shortcomings, we engineered universal CAR T-cell receptors that can be covalently modified with synthetic biomaterials by accelerated SpyCatcher003-SpyTag003 chemistry for cancer-cell targeting.
