The epidermal growth factor receptor (EGFR) represents an effective target for the treatment of non-small cell lung cancer. In the treatment of classical EGFR mutations, EGFR tyrosine kinase inhibitors have achieved desirable clinical efficacy. However, the effectiveness of tyrosine kinase inhibitors (TKIs) against the L861Q mutation has not been fully established.

Article Synopsis
  • Mutations in the EGFR gene are key drivers of non-small cell lung cancer (NSCLC), and afatinib has shown benefits for patients with rare EGFR mutations.
  • Researchers used the CRISPR method to create cell lines with the G719X mutation to test the effectiveness of tyrosine kinase inhibitors (TKIs).
  • The novel inhibitor WZ3146 was found to be effective against G719X mutant cells, inducing cell death and inhibiting growth through specific cellular pathways, suggesting it could be a promising treatment for these NSCLC patients.

Suppressor tRNAs are engineered or naturally occurring transfer RNA molecules that have shown promise in gene therapy for diseases caused by nonsense mutations, which result in premature termination codons (PTCs) in coding sequence, leading to truncated, often nonfunctional proteins. Suppressor tRNAs can recognize and pair with these PTCs, allowing the ribosome to continue translation and produce a full-length protein. This review introduces the mechanism and development of suppressor tRNAs, compares suppressor tRNAs with other readthrough therapies, discusses their potential for clinical therapy, limitations, and obstacles.

Purpose: EGFR classical mutations respond well to EGFR tyrosine kinase inhibitors. However, it is uncertain whether currently available EGFR-TKIs are effective against rare EGFR mutations and compound mutations. Herein, the effectiveness of almonertinib and alflutinib, the third-generation tyrosine kinase inhibitors developed in China, on rare EGFR S768I mutations and compound mutations is identified.

The tertiary mutation C797S in the structural domain of the EGFR kinase is a common cause of resistance to third-generation EGFR tyrosine kinase inhibitors (TKIs). In this study, we used a potent, selective and irreversible inhibitor, BDTX-189, to target EGFR C797S triple mutant cells for cell activity. The study constructed the H1975-C797S (EGFR L858R/T790 M/C797S) cell line using the CRISPR/Cas9 method and investigated its potential as a fourth-generation tyrosine kinase inhibitor via chemosensitivity approach.

Plant trichomes are specialized epidermal cells that protect plants from insects and pathogens. In Arabidopsis, epidermal hairs decrease as internodes increase in height, with only few epidermal hairs produced on the sepals abaxial surface of the early flowers. TRIPTYCHON (TRY) is known to be a negative regulator of epidermal hair development in Arabidopsis, suppressing the formation of ectopic epidermal hairs in the inflorescence.

The miR156-targeted squamosa promoter binding protein like (SPL) transcription factors function as an endogenous age cue in regulating plant phase transition and phase-dependent morphogenesis, but the control of SPL output remains poorly understood. In Arabidopsis thaliana the spatial pattern of trichome is a hallmark of phase transition and governed by SPLs. Here, by dissecting the regulatory network controlling trichome formation on stem, we show that the miR171-targeted lost meristems 1 (LOM1), LOM2 and LOM3, encoding GRAS family members previously known to maintain meristem cell polarity, are involved in regulating the SPL activity.
