The objective of the present study was to determine the effect of follicle size on recovery rate, quality, and in-vitro developmental competence of oocytes in Bos indicus cows. The ovaries (n = 507) of Bos indicus cows having age of 5-8 years, with mixed parity, BCS 2.75 ± 0.25, and clinically normal reproductive tracts were collected from the local abattoir. The follicles on the ovaries were divided into two groups based upon their size; 1) ≥6 mm diameter, and 2) less then 6 mm diameter. After initial evaluation of quality of the oocytes, the COCs were in vitro matured, fertilized, and cultured to determine the in vitro developmental competence. The oocyte recovery, quality, maturation, cleavage, 4-cell, 8-cell, and 16-cell stages were analyzed using PROC GLIMMIX procedure of SAS. However, the number of oocytes recovered per ovary was analyzed using MIXED procedure of SAS. Results revealed that the recovery of oocytes (LSM ± SEM) derived from the follicles having size less then 6 mm per ovary was greater (1.02 vs. 3.14 ± 0.13; P less then 0. 0001). However, the percentage (n/n) recovery [69.8 (474/679) vs. 62.7% (1454/2320); P = 0.01] and grade I_+_II oocytes [68.4 (324/474) vs. 57.9% (842/1454); P less then 0.0001] was greater in ≥6 mm as compared with less then 6 mm group, respectively. However, maturation rate did not differ [92.9 (288/310) vs. 92.2% (296/321); P = 0.98] between the groups. In contrast, cleavage rate [58.1 (180/310) vs. 47.4% (152/321); P = 0.01], the 4-cell [34.5 (107/310) vs. 18.7% (60/321); P = 0.0003], 8-cell [15.5 (48/310) vs. 7.8% (25/321); P = 0.008], and 16-cell [8.7 (27/310) vs. 2.1% (7/321); P = 0.004] stage embryos were greater in ≥6 mm group. It can be concluded that oocytes derived from follicle ≥6 mm have better in vitro developmental competence based on embryonic conversion in Bos indicus cows.The objective of this study was to investigate the influence of long-term temperature stress during the in vitro maturation (IVM) of oocytes on the in vitro embryo production (IVP) and the abundance of HSP70 and HSP90 in zebu cattle. Viable cumulus-oocyte complexes (COCs) were incubated for 24 h at 37 °C, 38.5 °C, or 40 °C for the low-, physiological, and high-temperature stress treatments, respectively. Thereafter, they were subjected to in vitro fertilization and culture. Temperature did not affect the polar body extrusion. However, IVP was adversely affected when IVM took place at 37 °C and 40 °C. The highest abundance of HSP70 was observed in cumulus cells after maturation of COCs at 40 °C. In contrast, HSP70 was more abundant in oocytes at both 37 °C and 40 °C; however, at 40 °C, the difference to the control group (38.5 °C) was not significant. In contrast, the highest abundance of HSP90 was observed in oocytes and cumulus cells at 37 °C. It appears that HSP70 and HSP90 respond to cold and heat stress in different ways. In conclusion, moderately high (40 °C) and low (37 °C) thermal stress for 24 h during IVM is detrimental to the developmental competence of oocyte and is accompanied by changes in the abundances of HSP70 and HSP90, especially in cumulus cells.The capecitabine and oxaliplatin (CapeOX) regimen is a commonly used adjuvant chemotherapeutic regimen for gastric cancer (GC). However, some patients exhibit a poor chemotherapy response due to genetic differences among individuals. Therefore, finding an effective sensitization strategy for CapeOX is important in the treatment of GC. The present study aimed to investigate the predictive biomarkers of the CapeOX chemotherapeutic outcomes for patients with GC. A total of 30 differentially expressed genes (DEGs) were identified using the gene expression profiles from The Cancer Genome Atlas capecitabine and oxaliplatin treatment GC cases and seven key DEGs [uroplakin-1b (UPK1B), fatty acid-binding protein, heart (FABP3), cystatin-M, caspase-5 (CASP5), corticosteroid 11-β-dehydrogenase isozyme 2, cytochrome P450 4X1 (CYP4X1) and epidermal growth factor receptor kinase substrate 8-like protein 3] were associated with survival. Gene validation was performed in clinical samples divided into recurrence and nonrecurrence groups. Patients with high or low expression of UPK1B, FABP3, CASP5 and CYP4X1 had markedly different overall survival rates. A model was established and the area under the curve of the receiver operating characteristic reached 0.875 (0.793-0.957), indicating that the model had good sensitivity and specificity.Linalool is an unsaturated terpene that can be found in several plants and exhibits various biological activities. The aim of the present study was to investigate the anticancer activity of linalool using the human prostate cancer 22Rv1 cell line. Flow cytometry was employed to study the effects of linalool on the induction of apoptosis, cell cycle progression, loss of mitochondrial membrane potential and cytochrome c release, whereas the effects of linalool on apoptosis-associated proteins were investigated by western blot analysis. An efficacy study was conducted using 22Rv1 tumor-bearing mice. Epigenetics inhibitor The expression of the cell proliferation markers Ki-67 and proliferating cell nuclear antigen (PCNA) in xenograft tumors was evaluated by immunohistochemistry. Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay was used to study the induction of apoptosis in an in vivo model. Linalool exerted an inhibitory effect on 22Rv1 cell proliferation and induced apoptosis in both in vitro and in vivo models. Western blot analysis indicated that both the mitochondria-mediated intrinsic and death-receptor-mediated extrinsic pathways were involved in the induction of apoptosis. Furthermore, linalool significantly reduced the expression of Ki-67 and PCNA in the 22Rv1 ×enograft model. The findings of the present study provide evidence supporting the anti-proliferative effects of linalool on 22Rv1 human prostate cancer cells, and suggest that linalool may be an effective agent for prostate cancer treatment.The prognosis of invasive pancreatic mucinous cystadenocarcinoma (MCC) is poor, and the molecular mechanism underlying its development remains unclear. The present study aimed to explore the potential role of autophagy in pancreatic MCC. The results demonstrated an increase in autophagy signaling in pancreatic MCC tissues and the MCC1 cell line compared with adjacent tissues and normal human pancreatic ductal epithelium (HPDE) cells. In addition, abnormal autophagy activation facilitated the migration and invasion of MCC1 cells. MicroRNA (miR)-224-5p expression levels were significantly higher in MCC1 cells compared with those in HPDE cells. Treatment with rapamycin further demonstrated that high levels of autophagy elevated miR-224-5p expression in MCC1 cells in a time-dependent manner. BCL2 was identified as a downstream target gene of miR-224-5p, which binds to the 3'-untranslated region of BCL2. In addition, the results of the present study demonstrated that BCL2 knockdown reversed the inhibition of autophagy mediated by the miR-224-5p inhibitor.
