Objective The aims of this study were to construct short hairpin RNA(shRNA)lentiviral vector in breast cancer T47D cells,to carry out RNA interference on lysine acetyltransferase 6B(KAT6B/MORF)gene,to down-regulate its expression and to explore its function.Methods Two pairs of single-stranded short hairpin RNA(shRNA5 and shRNA8)and the corresponding control sequences(Scramble5 and Scramble8)were synthesized based on the CDS of KAT6B gene.Polymerase chain reaction(PCR) was used to amplify double-stranded and ligated with the entry vector(pENTR/pSM2(CMV)GFP),which were subjected to a doub-le digestion(EcoRl and Xhol)linearization and homologous recombination with the entry vector(pENTR/pSM2(CMV)GFP)to obtain an entry clone containing the desired fragment.The target fragment was recombined onto the target vector(pLenti x1 puro DEST)via the LR cloning reaction of the Gateway system.The lentiviral packaging plasmids were co-transfected into HEK-293T cells with two pairs of target plasmids. The supernatant of HEK -293T cells was collected and transformed into T47D cells. The expression of KAT6B protein was detected in T47D cells by Western blot.Results The single colony obtained from the transformation was identi-fied by sequencing,which was consistent with the target sequence,indicating that the lentiviral vector had been successfully construc-ted.The expression of KAT6B protein was significantly lower in the shRNA KAT6B group than that in the control group,which indica-ted that the constructed gene silencing vector could play a role in the KAT6B gene in T47D cells.Conclusion The shRNA lentiviral gene silencing vectors of KAT6B were constructed and identified in T47D cells,which indicated that the foundation for further study

ObjectiveTo study the effect-enhancing and toxicity-reducing activities of astragalus polysaccharide injection (APS) on U14 cervical cancer in model mice receiving X-ray treatment. MethodU14 mouse cervical cancer cells were cultured in vitro and injected into the right forelimb armpit of Kunming mice for constructing a subcutaneous tumor-bearing model of cervical cancer. The tumor-bearing mice were randomly divided into the model group, X-ray intervention(IR, 6 Gy) group, APS (10 mL·kg-1·d-1) group, and IR + APS group. Following the observation of the state, body mass, and food intake of mice in each group, the volume of the tumor was measured. The tumor cell cycle and apoptosis were determined by flow cytometry. The protein and mRNA expression levels of apoptosis-related proteins p53, B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), and cleaved cysteine-dependent aspartate-directed protease-3 (Caspase-3) in tumor tissues were assayed by Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultThe comparison with the model group showed that mice in the IR group had poor mental status and reduced mobility. The IR group and IR + APS group exhibited reduced food intake and body mass since the 8th d (P<0.05, P<0.01) and narrowed tumor volume since the 9th d (P<0.01). In the IR group, the proportion of cells in the G1 phase was increased, while the proportion of those in the S phase was decreased (P<0.01). In the IR + APS group, the proportion of cells in the G1 phase rose, whereas the proportion of those in the G2 and S phases cells declined (P<0.05, P<0.01). The apoptotic rates in both the IR group and IR + APS group were elevated significantly (P<0.01). Compared with the model group, the IR group and IR + APS group displayed up-regulated cleaved Caspase-3 and Bax protein and mRNA expression in tumor tissues, but down-regulated Bcl-2 and p53 protein and mRNA expression (P<0.05, P<0.01). Compared with the IR group, the mice in the IR + APS group had better mobility and hair, normal body mass, and increased food intake (P<0.05). The tumor volume in the IR + APS group was reduced (P<0.05). The proportion of cells in the G2 phase was reduced, but the proportion of those in the S phase was raised (P<0.05). The apoptosis rate was increased (P<0.05). The apoptosis-related protein Bax protein expression in the tumor tissue was up-regulated, while the protein expression levels of Bcl-2 and p53 were down-regulated (P<0.05, P<0.01). ConclusionAPS maintains the life state of U14 cervical cancer model mice treated with X-ray and promotes tumor cell apoptosis, thus enhancing the efficiency and reducing toxicity.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.
