MiR-21 promoted invasion of fibroblasts by down-regulation of tissue inhibitor of metalloproteinase 3 (TIMP3) expression and increasing of matrix metalloprotein (MMP) expression in fibroblast cells via melanoma-derived exosomes in a time-dependent manner.

Our results suggest that tumor-derived exosomes may facilitate stromal fibroblasts an aggressive phenotype to equip the tumor progression.

Recent studies reported that circular RNAs (circRNAs) exert essential functions in hepatocellular carcinoma (HCC) progression. However, the expression profile and function of circular RNA PVT1 (circPVT1) in HCC are not fully addressed. Thus, we aimed to probe into the function of circPVT1 in HCC development.

The levels of circPVT1, microRNA-377 (miR-377) and transcripts encoding tripartite motif containing 23 (

) were determined by qRT-PCR. The stability and localization of circPVT1 were examined by RNase R digestion assay and subcellular fraction assay, respectively. Cell proliferation and apoptosis were evaluated by MTT assay and flow cytometry analysis, respectively. The relationship between miR-377 and circPVT1 or

was determined by dual-luciferase reporter assay and RNA immunoprecipitation (RIP). The protein expression of

was measured by Western blot. The glycolysis level was assessed by specific kits and Seahorse Extracellular Flux Analyzer XF96. The function of circPVT1 in vivo was investigated in a murine xenograft model.

CircPVT1 and

levels were elevated, while miR-377 was decreased in HCC. CircPVT1 knockdown restrained proliferation and glycolysis, but enhanced apoptosis in HCC cells. CircPVT1 could bind to miR-377 and inhibition of miR-377 restored circPVT1 knockdown-mediated effect on HCC cells.

was certified as a target of miR-377, and

upregulation overturned the influence of miR-377 upregulation or circPVT1 silence on HCC progression. Moreover, circPVT1 knockdown restrained tumor growth in HCC in vivo.

CircPVT1 aggravated the progression of HCC by upregulating

via sponging miR-377.

The phase III POLO trial demonstrated that olaparib as maintenance therapy for metastatic pancreatic cancer patients with a germline BRCA mutation had greater efficacy than placebo, but maintenance olaparib places an economic burden on patients. This study evaluated the cost-effectiveness of olaparib as maintenance therapy based on the POLO trial (NCT02184195).

A three-state Markov model (progression-free survival [PFS], progressive disease [PD] and death) based on data from the POLO trial was used to estimate the incremental cost-effectiveness ratio (ICER) of maintenance olaparib versus placebo for metastatic pancreatic cancer patients with a germline BRCA mutation. The cost was evaluated from the Chinese society's perspective, and health outcomes were assessed in terms of quality-adjusted life years (QALYs). The primary outcome was the ICER gained in terms of 2019 US$ per QALY. Model robustness was explored with one-way and probabilistic sensitivity analyses.

Compared with placebo, maintenance olaparib increased costs by $23,544.35 while gaining 0.69 QALYs, resulting in an ICER of $34,122.25 per QALY. The ICER was far higher than the commonly accepted willingness-to-pay threshold ($28,255.55 per QALY).

Compared with placebo, maintenance olaparib for metastatic pancreatic cancer patients with a germline BRCA mutation is not cost-effective in China.

Ribociclib has provided significant improvements in progression-free survival (PFS) and overall survival (OS) of postmenopausal patients with hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer (ABC). However, given the high cost of ribociclib, its value must be evaluated based on cost-effectiveness. Thus, we aimed to explore the cost-effectiveness of ribociclib for postmenopausal patients with HR-positive and HER2-negative ABC.

A comprehensive Markov model was developed to estimate the cost-effectiveness of ribociclib plus fulvestrant versus placebo plus fulvestrant as first-line treatment for HR-positive, HER2-negative ABC. Variables were estimated based on data from the randomized Phase III MONALEESA-3 trial. Ten-year values were estimated for quality-adjusted life years (QALYs), costs, and incremental cost-effectiveness ratios (ICERs). Direct treatment costs were estimated from the perspective of a United States payer. One-way and probabile HER2-negative ABC. PROTAC tubulin-Degrader-1 cost Despite the clinical benefits of ribociclib, its cost would need to decrease to provide more favorable economic outcomes.

TMED2 is a member of the transmembrane emp24 domain (Tmed)/p24 protein family, which is significantly upregulated in breast cancer, ovarian cancer and other tumour tissues. The purpose of this study was to investigate the expression of TMED2 in MM cell lines and its effect on the biological behaviour of MM cell lines.

Real-time quantitative PCR (RT-qPCR) was used to detect the expression of

in MM cell lines, including MM.1S and RPMI 8226 cells, and lentivirus vector-mediated

gene silencing was used to further study the effect of the downregulation of TMED2 expression on cell viability, the cell cycle, and apoptosis.

Based on the RT-qPCR results, the expression of the

mRNA was increased in the MM cell lines MM.1S and RPMI 8226 compared with endogenous control

. The expression of the

mRNA was substantially reduced after transfection of the shRNA targeting

(sh

) in both MM cell lines. The CCK-8 assay showed significant decreases in the viability of MM.1S and RPMI 8226 cells, suggesting that the

gene plays an important role in the proliferation of these two cell lines. The cell cycle of MM.1S and RPMI 8226 cells was substantially altered by sh

, as evidenced by the increased number of cells in G1 phase and decreased number of cells in S and G2/M phases. The FACS analysis revealed a significant increase in the apoptosis of MM.1S and RPMI 8226 cells due to the increased activity of Caspase 3/7, suggesting that the

gene is significantly related to the apoptosis of these two cell lines.

Based on these results, TMED2 may play an important role in the pathogenesis of MM. This novel study may contribute to further investigations of useful biomarkers and potential therapeutic targets in patients with MM.
