RESUMEN
Limb and CNS expressed 1 like (LIX1L) is over-expressed in several types of tumors. However, the function of LIX1L in glucose metabolism and hepatocellular carcinoma (HCC) progression remains elusive. Here we report that LIX1L is over-expressed in human HCC tissues, which predicts unfavorable prognosis. LIX1L deficiency
RESUMEN
Objective: To study the inhibitory effect of the medicine group of promoting blood circulation and removing stasis (PBCRS) on breast cancer induced by 7, 12-dimethylbenz(a)anthracene (DMBA) in rats, and screen out and verify key genes based on RNA Sequencing (RNA-seq) technology and Ingenuity Pathway Analysis (IPA). Method: Totally 96 Sprague-Dawley (SD) rats were randomly divided into blank group, DMBA model control group, tamoxifen (TAM) group (1.9 mg·kg-1·d-1), high-dose, middle-dose and low-dose PBCRS groups (12.96, 6.48, 3.24 g·kg-1·d-1). One week after drug intervention, except for the blank group, the DMBA was used to induce the rat model of breast cancer (with an interval of a week, irrigation for two times at the dose of 100 mg·kg-1). After 10 weeks, the changes in tumor weight and tumor volume were observed. The total RNA was extracted by total RNA extraction kit, and three RNA samples were collected from the DMBA model control group and the middle-dose PBCRS group for genetic testing. Based on RNA-seq, key differential genes were screened out and verified by Real-time PCR. Result: Comparing with the DMBA model control group, the tumor volume and tumor weight in middle-dose PBCRS group were decreased significantly (PPConclusion: PBCRS may inhibit the occurrence of breast cancer by interfering with the expression of FBP1 in breast cancer tissue.
RESUMEN
OBJECTIVE: To analyze the clinical and molecular genetic characteristics of 2 cases of fructose-1,6-bisphosphatase deficiency in the same family to provide evidence for the precise treatment,genetic counseling and prenatal diagnosis.METHODS: Clinical data were collected from 2 patients with hypoglycemia encephalopathy,and molecular genetic analysis was performed using targeted capture next-generation sequencing. RESULTS: The 2 patients were siblings,the male proband was 7 years old,mainly manifested with convulsions after hunger or ingestion of a large amount of fructose,accompanied by ketoacidosis;clinical diagnosis was hypoglycemia encephalopathy,and fructose metabolism abnormalities was suspected. The younger brother was 4 years old,mainly showing hunger and sweating in the morning,stomach ache after eating fruit,and convulsion episode once after hunger. Next-generation sequencing results showed that the siblings had c.333+1＿2 delinsTC and c.490 G>A compound heterozygous mutations in the FBP1 gene,and their parents were carriers with normal phenotype.The c.333+1＿2 delins TCis a novel mutation,c.490 G>A is a reported pathogenic mutation,and the two patients were diagnosed with fructose-1,6-bisphosphatase deficiency genetically. CONCLUSION: For children with unexplained hypoglycemia,convulsions and metabolic acidosis,the fructose-1,6-bisphosphatase deficiency should be considered. Early genetic analysis is helpful to clarify the cause,make precise treatment and improve prognosis.
RESUMEN
Objectives To explore the genetic diagnosis of fructose 1,6 diphosphatase deficiency and analysis of mutation sites of its pathogenic genes. Methods The clinical data and the related results of gene panel screening in one child with fructose 1, 6 diphosphatase (FBPase) deficiency were retrospectively reviewed. Results The 2-year-old girl suffered repeated infection, nausea, vomiting, mental illness, and drowsiness, accompanied by intermittent convulsions. Blood biochemical tests sμggested hypoglycemia and acidosis.The FBP1 gene had a missense mutation,c.355G>A,p.Asp119Asn(isozygoty).Both her parents carried the locus variation (heterozygous). Conclusions Fructose 1, 6 diphosphatase deficiency should be considered when child with hypoglycemia after repeated infection, acidosis, and ketosis.
