"Utilizing The Cancer Genome Atlas (TCGA) database, it was revealed that USP30-AS1 was one of the most dysregulated lncRNAs in cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), suggesting that USP30-AS1 may exert important roles during cervical cancer progression."

"Thus, we conducted a stepwise Cox regression analysis of 37 lncRNAs with survival significance and finally obtained a gene combination ( xref , xref ) composed of seven lncRNAs (HLA-DQB1 antisense RNA 1 (HLA-DQB1-AS1), USP30 antisense RNA 1 (USP30-AS1), AL645929, AL365361, long intergenic nonprotein coding RNA 520 (LINC00520), LINC00324, and AC055822)."

"As the present study demonstrated that USP30-AS1 functions as a ceRNA to positively regulate PTP4A1 expression by sequestering miR-299-3p in cervical cancer, rescue experiments were performed to understand whether the tumour-promoting roles of USP30-AS1 were mediated by the miR-299-3p/PTP4A1 axis."

"Calculate the risk score of ccRCC patients according to the formula: risk score = (0.217 × CARS expression level) + (0.0098 × CD44 expression level) + (−0.0053 × DPP4 expression level) + (−0.307 × USP30-AS1 expression level) + (0.103 × GCLC expression level) + (−0.151 × HMGCR expression level) + (−0.0006 × HSPB1 expression level) + (−0.0094 × NCOA4 expression level) + (−0.0024 × SAT1 expression level) + (0.1523 × PHKG2 expression level) + (−0.007 × GOT1 expression level) + (−0.0024 × HMOX1 expression level)."

"Among these, LncRNA USP30−AS1 had co-expression relationship with 9 ferroptosis-related genes (CYBB, SOCS1, IFNG, TNFAIP3, PML, GCH1, NCF2, SLC2A6, and CAPG), LncRNA LIPE-AS1 was co-expressed with 5 ferroptosis-related genes (HRAS, PHKG2, MAPK14, EGLN2, and GPX4) and there was a co-expression relationship between AC108474.1 and 5 ferroptosis-related genes (TAZ, ISCU, CAV1, PLIN4, and HIC1)."

"By comparing the noncoding RNAs of different immune‐infiltrating groups, we found that 6 differentially expressed lncRNAs (AC092580.4, CTA‐384D8.35, AC002331.1, USP30‐AS1, GATA3‐AS1, and AC019117.1) and 11 differentially expressed miRNAs (mir142, mir223, mir7702, mir4772, mir155, mir150, mir187, mir429, mir200a, mir551b, and mir200b) were associated with immune infiltration."

"Next, we studied each lncRNA in our signature and found that AC024060.1, AC105942.1, AL031775.1, USP30-AS1, and MAFG-DT-LNC were merely reported once in BC predictive signatures, like immune-related lncRNA signature [ xref ], epithelial mesenchymal transition-related lncRNA signature [ xref ], tumor-infiltrating B lymphocytes lncRNA signature [ xref ]."

"Furthermore, in accordance with our findings, some other studies mainly based on the bioinformatics analysis have also reported that LINC02408 [ xref ] and YTHDF3-AS1 [ xref ] are connected with the poor prognosis of BC patients, but USP30-AS1 [ xref ], U73166.1 [ xref ], and LINC01016 [ xref ] can be taken as the protective factors of prognosis."

"We identified and included 15 prognostic ferroptosis-related lncRNAs (AL356740.1, FOXC2AS1, ZNF528AS1, LINC02535, PSMB8AS1, AL590428.1, AP000347.2, OCIAD1-AS1, AP001347.1, AC104986.2, AC018926.2, LINC00867, AC099518.4, USP30-AS1, and ARHGAP5-AS1), to build our ferroptosis-related lncRNAs risk model."

"Univariate Cox regression analysis results showed that AP000695.1 (HR: 1.73, 95% CI: 1.05–2.85, p -value: 0.033) was a risk factor of ovarian cancer while LINC00996 (HR: 0.422, 95% CI: 0.235–0.758, p -value: 0.00388) and USP30-AS1 (HR: 0.794, 95% CI: 0.677–0.931, p -value: 0.00464) were protective factors of ovarian cancer ( xref )."

"Rapid progress in sequencing technology nowadays has bought noncoding RNA (ncRNA) to light, exceptionally long non‐coding RNAs (lncRNAs), which have critical roles in malignant transformation and progression. xref LncRNAs are participators in regulating gene expression through chromatin modification and the process of transcriptional and posttranscriptional. xref As more and more studies on lncRNA function have been revealed, lncRNAs can regulate biologic processes and serve as a prognostic biomarker in many solid tumors. xref , xref , xref , xref , xref Moreover, lncRNAs also regulate the hemopoiesis system. xref For example, HOTTIP is abnormally activated in AML, and HOTTIP loss leads to the inhibition of genes crucial for hematopoiesis and AML leukemogenesis. xref Knockdown of LncRNA ANRIL results in a drop in glucose uptake and blockage of AML cell maintenance. xref In addition, lncRNA USP30‐AS1 is highly expressed in AML and promotes the survival of acute myeloid leukemia cells by cis‐regulating USP30 and ANKRD13A. xref "

"Next, we identified six immunophenotype-related long non-coding RNA biomarkers (im-lncRNAs, USP30-AS1, HCP5, PSMB8-AS1, AL133264.2, LINC01684, and LINC01506) by employing a machine learning computational framework combining minimum redundancy maximum relevance algorithm (mRMR) and random forest model."

"As indicated by immunofluorescence test (Fig. xref C), knockdown of ANKRD13A and USP30-AS1 increased the abundance of HLA-1 protein in the cell membrane of KG-1 cells; the effect exerted by USP30-AS1 knockdown was abolished by ANKRD13A overexpression; overexpression of ANKRD13A and USP30-AS1 individually was associated with very low level of HLA-1 protein in the cell membrane of KG-1 cells."

"This study employed the LASSO regression method to establish an autophagy-related lncRNA signature containing AC084018.1, AC092171.2, AP000695.1, GAS6-AS1, LINC00174, LINC00893, LINC00996, MEIS1-AS3, MIR22HG, NEAT1, TEX26-AS1, U73169.1, UBE2Q1-AS1, and USP30-AS1 for ovarian cancer based on abnormally expressed autophagy-related lncRNA profiles."

"Among these 12 lncRNAs constructing the prognostic signature, LINC02408, AL589765.4, AL121790.2, YTHDF3-AS1, LINC00460, and CYTOR functioned as risk factors for the prognosis of BC patients, while AC068473.4, USP30-AS1, U73166.1, LINC00987, CD2BP2-DT, and LINC01016 acted as protective factors."

"However, fragments without the region (250–500 bp) showed very weak capacity to bind ASH2L. Therefore, the region (250–500 bp) is very important for USP30-AS1 binding to ASH2L. To determine whether ASH2L is implicated in the regulatory effect of USP30-AS1 on USP30 and ANKRD13A expression, we knocked down or overexpressed ASH2L in KG-1 and HL-60 cells (Fig. xref D)."

"The USP30-AS1 lncRNA is an antisense transcript to the USP30 gene that has been implicated in mitochondrial quality control in some cancers and also in the progression of virus-induced cancers such as malignant cervical tumors [55, 56] , and is mainly upregulated in those SARS-CoV-2 patients with higher viral loads."
