HTB50-2 Inhibits Growth and Migration of Triple-negative Breast Cancer via FOSL2/FOXC1 Signaling Axis and Subsequent Ferroptosis.

Background: The manipulation of ferroptosis in cancer cells is a possible therapeutic technique that has been investigated for use in the treatment of cancer. Consequently, ferroptosis-inducing medications have recently received increased interest in cancer therapy. In this research, we assessed the anticancer efficacy of 14β-hydroxy- 3β-(β-D-Glucopyranosyloxy)-5α-bufa-20,22-dienolide (HTB50-2), a natural product derived from the plant Helleborus thibetanus Franch, in Triple-Negative Breast Cancer (TNBC).

Natural compound So-2 suppresses triple-negative breast cancer through inducing ferroptosis via downregulating transcription factor E2F7.

Triple-negative breast cancer (TNBC), accounting for about 15∼18% of all breast cancers, is notorious for its poor prognosis, high rate of relapse and short overall survival. Because of lacking effective therapeutic targets or drugs, treatment of TNBC in clinical encounters great obstacle. Siegesbeckiaorientalis L.

YF343, A Novel Histone Deacetylase Inhibitor, Combined with CQ to Inhibit- Autophagy, Contributes to Increased Apoptosis in Triple- Negative Breast Cancer.

Background: Compounds that target tumor epigenetic events are likely to constitute a prominent strategy for anticancer treatment. Histone deacetylase inhibitors (HDACis) have been developed as prospective candidates in anticancer drug development, and currently, many of them are under clinical investigation. We assessed the anticancer efficacy of a now hydroxamate-based HDACi, YF-343, in triple-negative breast cancer development and studied its potential mechanisms.

Transforming Growth Factor-β Receptor III is a Potential Regulator of Ischemia-Induced Cardiomyocyte Apoptosis.

Background: Myocardial infarction (MI) is often accompanied by cardiomyocyte apoptosis, which decreases heart function and leads to an increased risk of heart failure. The aim of this study was to examine the effects of transforming growth factor-β receptor III (TGFβR3) on cardiomyocyte apoptosis during MI.

Methods And Results: An MI mouse model was established by left anterior descending coronary artery ligation.

Volatility, irregularity, and predictable degree of accumulative return series.

Recently it was shown that financial time series are not completely random process but exhibit long-term or short-term dependences, which offer promises for predictability. However, we do not clearly understand the potential relationship between serial structure and predictability. This paper proposed a framework to magnify the correlations and regularities contained in financial time series through constructing accumulative return series.

Fairness emergence from zero-intelligence agents.

Fairness plays a key role in explaining the emergence and maintenance of cooperation. Opponent-oriented social utility models were often proposed to explain the origins of fairness preferences in which agents take into account not only their own outcomes but are also concerned with the outcomes of their opponents. Here, we propose a payoff-oriented mechanism in which agents update their beliefs only based on the payoff signals of the previous ultimatum game, regardless of the behaviors and outcomes of the opponents themselves.
