Tumor suppression of Transforming Growth Factor (TGF-β) signaling pathway requires an adaptor protein, Embryonic Liver Fodrin (ELF). Disruption of ELF expression resulted in miscolocalization of Smad3 and Smad4, then disruption of TGF-β signaling. However, the prognostic significance of ELF for hepatocellular carcinoma (HCC) hasn't been clarified. This study aimed to investigate whether measuring both TGF-β1 and ELF provides a more powerful predictor for HCC prognosis than either marker alone.

The prognostic value of combined TGF-β1 and ELF in hepatocellular carcinoma.

The occurrence and development of hepatocellular carcinoma (HCC) depends largely on such non-tumor factors as inflammatory condition, immune state, viral infection and liver fibrosis. Various inflammation-based prognostic scores have been associated with survival in patients with HCC, such as the neutrophil/lymphocyte ratio (NLR), the platelet/lymphocyte ratio (PLR) and the prognostic nutritional index (PNI). The aspartate aminotransferase/platelet count ratio index (APRI) is thought to be a biomarker of liver fibrosis and cirrhosis. This study aims to evaluate the ability of these indices to predict survival in HCC patients after curative hepatectomy, and probe the increased prognostic accuracy of APRI combined with established inflammation-based prognostic scores.

A novel and accurate predictor of survival for patients with hepatocellular carcinoma after surgical resection: the neutrophil to lymphocyte ratio (NLR) combined with the aspartate aminotransferase/platelet count ratio index (APRI).

The function of hornerin (HRNR), a member of the S100 protein family, is poorly clarified in the development of human tumors. The role of HRNR in hepatocellular carcinoma (HCC) progression is investigated in the study.

Hornerin promotes tumor progression and is associated with poor prognosis in hepatocellular carcinoma.

The abnormal expression of long noncoding RNAs (lncRNAs) is associated with human carcinoma. The present study aimed to investigate the mechanisms underlying the function of lncRNA AK002107 in the progression of hepatocellular carcinoma (HCC). The differential expression of lncRNAs between HCC and paired nontumor tissues was identified using microarrays, and the correlation between the expression of lncRNA AK002107 and the clinical prognosis of HCC was analyzed. We investigated the role of lncRNA AK002107 in HCC tumor biology in vitro using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT), colony formation, and Matrigel invasion assays and in vivo by assessing the growth of xenografted HCC tumors. The potential microRNAs that interact with lncRNA AK002107 were identified using online tools and were verified using PCR and luciferase reporter assay. The levels of TGFBR1, E-cadherin, and vimentin were determined using western blot assays. We then further investigated the correlation between expression of lncRNA AK002107 with miR-140-5p and TGFBR1 expression in HCC tissues. The expression of lncRNA AK002107 is frequently upregulated in HCC samples and cell lines. Patients with HCC who have elevated lncRNA AK002107 expression exhibit poorer overall survival and disease-free survival. Silencing lncRNA AK002107 expression significantly inhibited HCC cell proliferation, colony formation, and invasion both in vitro and in vivo. Furthermore, lncRNA AK002107 directly binds to miR-140-5p and significantly inhibits miR-140-5p expression. The functions of lncRNA AK002107 in cell growth and tumor invasion are mediated via miR-140-5p. lncRNA AK002107 upregulated TGFBR1 expression and then induced epithelial-mesenchymal transition (EMT) by inhibiting miR-140-5p expression. The expression of lncRNA AK002107 inversely correlated with miR-140-5p expression and positively correlated with TGFBR1 expression in HCC tissues. In summary, lncRNA AK002107 functions as an oncogene in tumors by inhibiting miR-140-5p, targeting TGFBR1, and then inducing EMT. The lncRNA AK002107/miR-140-5p/TGFBR1/EMT regulatory network may be a valuable target for the development of novel diagnostic and treatment methods for HCC.

The long noncoding RNA AK002107 negatively modulates miR-140-5p and targets TGFBR1 to induce epithelial-mesenchymal transition in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is the sixth most commonly diagnosed malignancy and the third leading cause of cancer-related deaths worldwide. A 58-year-old man visited his local hospital due to abdominal discomfort and was diagnosed with lung metastasis. After admission to our hospital in April 2020, he received two cycles of transcatheter arterial embolization (TAE), hepatic arterial infusion chemotherapy (HAIC-Folfox), sorafenib, and camrelizumab every 3 weeks. Due to the end of HAIC treatment, he underwent drug-eluting transcatheter arterial chemoembolization (dTACE) once, sorafenib, and camrelizumab. However, because of worsening liver function, we interrupted TACE and only gave sorafenib and camrelizumab in August 2020. Although he received systemic therapy, the tumors still rapidly progressed and we considered the possibility of tumor resistance. Subsequently, regorafenib was given. In September, the patient underwent conventional TACE (cTACE) once, regorafenib, and camrelizumab. After half a year of comprehensive treatment, the treatment effect was not satisfactory, and he returned to the local hospital to received regorafenib every day and camrelizumab once every 3 weeks. The patient found that the tumor and lung metastasis had shrunk significantly after 1 year of the initial diagnosis, then he was admitted to our hospital and received surgery treatment, and now he has survived disease-free for 6 months.
