Article Abstract

The study of FOXO1, a pivotal transcription factor, has garnered significant attention due to its critical role in diverse cellular processes, including lineage differentiation, apoptosis, cell cycle regulation, and metabolism. To comprehensively understand the functional intricacies of FOXO1, an innovative approach is essential. This chapter highlights employing CRISPR exon scanning as a strategic tool to dissect the functional domains of FOXO1 and unravel its diverse regulatory functions. CRISPR exon scan allows for the identification of functionally important domains based on the levels of sgRNA depletion or enrichment within the FOXO1 gene, providing a unique opportunity to investigate the domain function under relevant biological contexts. This approach enables the systematic exploration of FOXO1's structural domains, shedding light on how distinct regions contribute to its overall function. The comprehensive exon scan analysis using CRISPR technology allows gaining a nuanced understanding of FOXO1's functional diversity and regulatory mechanisms.

The shift from vegetative to reproductive growth is an important developmental transition that affects flowering and maturation, architecture, and ecological adaptability in plants. The florigen-antiflorigen system universally controls flowering and plant architecture, and changes to the ratio of these components alter this transition and disrupt growth. The genes FT (FLOWERING LOCUS T), encoding the florigen protein FT, and CETS [CENTRORADIALIS (CEN)/TERMINAL FLOWER1 (TFL1)/SELF-PRUNING (SP)], encoding antiflorigen proteins, have opposing roles.

Orofacial clefting (OFC) is a frequent congenital anomaly and can occur either in the context of underlying syndromes or in isolation (nonsyndromic). The two common OFC phenotypes are cleft lip with/without cleft palate (CL/P) and cleft palate only (CPO). In this study, we searched for penetrant CL/P genes, by evaluating de novo copy number variants (CNV) from an exome sequencing dataset of 50 nonsyndromic patient-parent trios.

Sterol regulatory element-binding protein 1 (SREBP1) is an important transcription factor that controls lipid metabolism and adipogenesis. Two isoforms, SREBP1a and SREBP1c, are generated by alternative splicing of the first exon of the gene. The porcine gene has mainly been studied for its role in lipid metabolism in adipose tissues, but little is known about its involvement, and the role of its two isoforms, in adipogenesis.

Mutations in the CsEMS1 gene result in male sterility and reduced wart number and density. Male sterility and fruit wart formation are two significant agronomic characteristics in cucumber (Cucumis sativus), yet knowledge of our underlying genetics is limited. In this study, we identified an EMS-induced male sterility and few small warts mutant (msfsw).

Aim: This study aimed to create an f9l mutant zebrafish using clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) and characterize its coagulation properties to investigate its functional similarity to human FX and explore the potential synergy between f9l and f10.

Methods: Three gRNAs targeting exon 8 encoded by the catalytic domain of the f9l gene were injected into 300 single-cell zebrafish embryos using CRISPR/Cas9 technology. DNA from the resulting adults was extracted from tail tips, and PCR was used to detect indels.
