Abstract
BACKGROUND Breast cancer is a prevalent malignant tumor that affects women worldwide. The primary challenge in treating breast cancer is combating drug resistance, which contributes to relapse and metastasis. Jatrophone is a unique macrocyclic jatrophane diterpene found in various Jatropha and Euphorbia species. It possesses diverse biological and pharmacological activities, including anticancer activity. However, it is unclear whether jatrophone can overcome drug resistance in breast cancer. METHODS This study includes the investigation of the cytotoxicity of jatrophone on doxorubicin-resistant breast cancer cells (MCF-7ADR) and the underlying molecular mechanisms. The effects of jatrophone on cell viability were determined using the sulforhodamine B (SRB) assay, while flow cytometry was used to evaluate cell cycle progression, apoptosis, and autophagy. A scratch assay was conducted to observe cell migration, and western blotting was used to measure downstream protein levels (PI3K, AKT, and NF-κB). Unpaired Student's t-tests were used for comparison between the two groups and the results were analyzed by one-way ANOVA with Tukey- Kremer post hoc test. RESULTS It was shown that jatrophone exhibited potent cytotoxic activity on MCF-7ADR cells in a dose-dependent manner, with an IC50 value of 1.8 µM. It also significantly induced cell cycle S and G/M phase arrest. Interestingly, jatrophone induced both early and late apoptotic cell death, as well as autophagic cell death, with negligible necrosis. Furthermore, jatrophone treatment diminished the migration of MCF-7ADR cells. At the molecular level, jatrophone treatment significantly down-regulated the expression levels of PI3K, AKT, and NF-κB. β. CONCLUSIONS The results of the study suggest that jatrophone decreases the proliferation of MCF-7/ADR cells at a low micromolar concentration; induces cell cycle arrest; promotes apoptotic, and autophagic cell death; inhibits migration and EMT; and works on resistance by a mechanism involving the inhibition of the PI3K/Akt/ NF-κB pathway. These findings provide evidence of the potential of jatrophone to be a promising lead compound for targeting doxorubicin-resistant breast cancer cells and could be further investigated for its clinical application as a chemotherapy adjuvant.

Abstract
Gossypol is a yellow natural polyphenolic compound extracted from the seeds, leaves, stems, and flower buds of the cotton plant. Several studies have shown that exposure to gossypol impacts reproductive health in both humans and animals. However, whether gossypol exposure would influence oocyte quality has not yet been determined. Here, we studied the effects of gossypol on the meiotic maturation of mouse oocytes in vitro. The results revealed that gossypol exposure did not affect germinal vesicle breakdown (GVBD) but significantly reduced polar body extrusion (PBE) rates. Moreover, we observed meiotic spindle organization and chromosome alignment were entirely disturbed after gossypol exposure. Further, gossypol exposure also caused mitochondrial dysfunction and abruptly decreased the levels of cellular ATP, and diminished the mitochondrial membrane potential (MMP). Accordingly, gossypol-induced oxidative stress was confirmed through an increased level of reactive oxygen species (ROS). Early apoptosis incidence also increased as identified by positive Annexin-V signaling. Collectively, the above findings provide evidence that gossypol exposure impaired oocyte meiotic maturation, disturbed spindle structure and chromosome dynamics, disrupted mitochondrial function, induced oxidative stress, and triggered early apoptosis. These findings emphasize gossypol's adverse effects on oocyte maturation and thus on female fertility.

Abstract
Cord blood (CB) has been used as an alternative source for unrelated allogeneic hematopoietic stem cell transplantation. To determine which assay was useful for predicting the successful outcome of CB transplantation, CBs were grouped according to the temperature (4 °C, 24 °C, and 37 °C) and time (24, 48, and 72 h) after collection. The viability, early apoptosis, and colony forming units (CFUs) were ascertained for the total nucleated cells (TNCs) and CD34+ cells; in addition, the engraftment of infused CD34+ cells in NSG mice was determined. The viability of the TNCs and CD34+ cells and total CFUs were significantly decreased whereas the early apoptosis was significantly increased in the 72 h group at 37 °C compared to that of the 24 h group at 24 °C. The viability and early apoptosis of the TNCs correlated with those of CD34+ cells. In addition, the viability and early apoptosis correlated with the number of granulocyte/monocyte progenitor CFUs. In transplanted NSG mice, the frequency of human CD45+ cells decreased in the 72 h group at 24 °C compared to that of the 24 h group at 24 °C and was negatively correlated with early apoptosis of TNCs and CD34+ cells. This study demonstrated that the early apoptosis of TNCs and CD34+ cells constitutes a useful marker for predicting the engraftment of HSCs and may provide helpful data for standard assessment regarding CB quality by analyzing the correlation between in vitro and in vivo assays using NSG mice.

Abstract
Pentachlorophenol (PCP) is a widespread, persistent environmental contaminant, and it is enzymatically activated to form a reactive metabolite, tetrachloro-1,4-benzoquinone (TCBQ). To our knowledge, there is no information about TCBQ toxicity on embryonic stem cells. Here, we demonstrated that TCBQ induced significantly apoptosis of mouse embryonic stem cells in a concentration-dependent manner. We also showed that TCBQ elevated genomic 5-hydroxymethylcytosine (5hmC) by affecting ten-eleven translocation (Tet) dioxygenases in mouse embryonic stem cells. We further investigated whether Tet dioxygenases were implicated in TCBQ-induced apoptosis. By depleting all three dioxygenases (Tet1-3), we found that Tet dioxygenases slightly inhibited both early and late apoptosis induced by TCBQ at a low concentration (30μmol/L). Meanwhile, treated by TCBQ at higher concentrations (40 and 50μmol/L), the total percentage of apoptotic cells was not affected by Tet dioxygenases. However, Tet dioxygenases tended to arrest mouse ES cells to be at early apoptotic stage and to reduce the cells to enter later apoptotic stage. These results indicate that Tet dioxygenases play a role in shaping TCBQ-induced apoptosis in mouse embryonic stem cells. Our study provides new insights into the toxicology of PCP and its reactive metabolite TCBQ.

Abstract
Traumatic brain injury (TBI) is a commonly encountered emergency and severe neurosurgical injury. Previous studies have shown that the presence of the apolipoprotein E (APOE) ε4 allele has adverse outcomes across the spectrum of TBI severity. Our objective was to evaluate the effects of APOE alleles on trauma induced early apoptosis via modification of delayed rectifier K(+) current (Ik(DR)) in neuronal/glial co-cultures model. An ex vivo neuronal/glial co-cultures model carrying individual APOE alleles (ε2, ε3, ε4) of mechanical injury was developed. Flow cytometry and patch clamp recording were performed to analyze the correlations among APOE genotypes, early apoptosis and Ik(DR). We found that APOEε4 increased early apoptosis at 24h (p<0.05) compared to the ones transfected with APOEε3 and APOEε2. Noticeably, APOEε4 significantly reduced the amplitude of the Ik(DR) at 24h compared to the APOEε3 and APOEε2 (p<0.05) which exacerbate Ca(2+) influx. This indicates a possible effect of APOEε4 on early apoptosis via inhibiting Ik(DR) following injury which may adversely affect the outcome of TBI.

Abstract
AIM: To investigate the effects of interferon-α on the early apoptosis of activated hepatic stellate cells (HSCs), and to further explore the anti-fibrosis mechanism of interferon-α (IFN-α).
METHODS: Rat HSCs were cultured in vitro, and then treated with different concentrations of IFN-α for 24 h. The viable cell count was measured by MTT assay, and the early apoptosis of HSCs was detected by flow cytometry using AnnexinV/PI-staining.
RESULTS: MTT assay showed a decrease of HSCs after IFN-α treatment, and the absorbency was significantly different from that of the control cells when 1 × 107 and 1 × 108 U/L IFN-α was used (t = 2.82, 5.44, both P < 0.05). Flow cytometry demonstrated that the early apoptosis rate of HSCs was increased with the elevation of IFN-α concentration, and the apoptosis rate was markedly different from that of the control cells when IFN-α was adopted at the concentrations of 1 × 107 and 1 × 108 U/L (t = 4.31, 5.07, both P < 0.05).
CONCLUSION: IFN-α can induce the early apoptosis of HSCs, which is probably one of the anti-fibrosis mechanism of interferon-α.
