Small RNA Toxin‐Assisted Evolution of GC‐Preferred ErCas12a for Enhanced Genome Targeting Range

open access: yesAdvanced Science, EarlyView.
ErCas12a is engineered to target GC‐rich PAMs using a small RNA toxin‐aided positive screening system. The resulting variant, enErCas12a, exhibits an expanded PAM profile and facilitates efficient gene editing in both bacterial and mammalian cells, while preserving high targeting specificity for both canonical and non‐canonical PAM targets.

Semaphorin 3E‐Plexin‐D1 Pathway Downstream of the Luteinizing Hormone Surge Regulates Ovulation, Granulosa Cell Luteinization, and Ovarian Angiogenesis in Mice

open access: yesAdvanced Science, EarlyView.
The Semaphorin 3E (Sema3E)‐Plexin‐D1 pathway mediated by C/EBPα and C/EBPβ downstream of the luteinizing hormone (LH) surge plays important roles in the mouse preovulatory ovary. Timely activation and suppression of this pathway during the preovulatory stage are crucial for ovulation, corpus luteum formation, and proper angiogenesis.

PABPN1 Couples the Polyadenylation and Translation of Maternal Transcripts to Mouse Oocyte Meiotic Maturation

open access: yesAdvanced Science, EarlyView.
This study reveals that cytoplasmic PABPN1 is essential for mouse oocyte meiotic maturation by coordinating polyadenylation, translation, and degradation of maternal mRNAs. Pabpn1 knockout disrupts CDK1 activation, spindle formation, and chromosome alignment by impairing maturation‐promoting factor (MPF) regulation and BTG4‐mediated deadenylation ...

Accounting for ALA Natural Mutations Enhances the Efficiency of Graphene Oxide Nanopriming in Bar‐Modified Arabidopsis

open access: yesAdvanced Science, EarlyView.
Nanopriming enhances plant resilience to environmental challenges; however, its effectiveness across diverse genetic backgrounds, including genetic modifications and natural variations, remains uncertain. These findings demonstrate that nanopriming improves efficacy when natural genetic variations are considered, particularly in genetically modified ...

Engineered Genetic Circuits Activated by Bezafibrate Improve ESC‐Based TAA Cancer Vaccine Efficacy and PD‐L1 Nanobody Therapy

open access: yesAdvanced Science, EarlyView.
Synthetic gene circuits regulated by bezafibrate are developed to express tumor antigens and PD‐L1 nanobody (PD‐L1nb), enhancing cancer immunotherapy. Delivered via HEK293T cells, ESCs, or directly injected the plasmids containing the circuit into the tumor, the circuits reduce tumor growth, boost CD8+ T cells, and minimize T cell exhaustion.
