Brolucizumab after failure of aflibercept with photodynamic therapy in polypoidal choroidal vasculopathy: A case report.

We describe one case of polypoidal choroidal vasculopathy with persistent subretinal fluid despite multiple treatment with intravitreal Bevacizumab, Ranibizumab and Aflibercept, as well as Aflibercept associated with photodynamic therapy. The patient reached complete resolution after intravitreal Brolucizumab injection, but experienced recurrence of subretinal fluid 12 weeks after discontinuation. Brolucizumab might be an option in treating subretinal fluid after failure of other anti-VEGF agents associated with photodynamic therapy.

LncRNA INHBA-AS1 promotes colorectal cancer cell proliferation by sponging miR-422a to increase AKT1 axis.

OBJECTIVE: In recent years, long non-coding RNAs (lncRNAs) have emerged for regulating the development, as well as progression in colorectal cancer (CRC), which assists in finding new targets for CRC treatment. A previous study indicated that INHBA-AS1 promotes oral squamous cell progression by sponging miR-143-3p. However, the exact function possessed by lncRNA INHBA-AS1 in CRC development remains unclear. PATIENTS AND METHODS: The expression level of INHBA-AS1 in CRC tissues and cell lines was determined by qRT-PCR. The functional role of INHBA-AS1 in CRC was investigated by a series of in vitro assays. RNA immunoprecipitation (RIP), bioinformatics analysis was utilized to explore the potential mechanisms of INHBA-AS1. RESULTS: The present study identified INHBA-AS1 as a kind of lncRNA with high expression in CRC tissues and cells. Functionally, NHBA-AS1 downregulation in CRC cells suppressed CRC cell proliferation as well as colony formability. Mechanistically, INHBA-AS1/miR-422a/AKT1 established the ceRNA network to regulate MMP-2, -7, -9 expressions that participated the modulation of CRC progression. CONCLUSIONS: In summary, LncRNA INHBA-AS1 contributes to CRC progression through AKT1 pathway, and provides a new mechanism to regulate CRC development, as well as a potential target for treating CRC.
