H19, a maternally expressed imprinted gene transcribing a long noncoding RNA, has previously been reported to be involved in tumorigenesis and cancer progression. However, the association between the H19 polymorphisms and breast cancer (BC) susceptibility has remained elusive. The aim of this study was to evaluate the associations between 2 H19 haplotype tagging SNPs (rs3741219 T>C, rs217727 C>T) and the risk of breast cancer.Our study comprised 464 BC patients and 467 cancer-free controls in China. rs3741219 and rs217727 were genotyped with polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) and created restriction site PCR (CRS-RFLP) assays, respectively. False-positive report probability (FPRP) was calculated to test the false-positive association.On performing univariate analysis, no significant association between H19 polymorphisms (rs3741219 and rs217727) and BC was observed. However, in further stratified analyses, CT+TT genotypes of rs217727 had a significantly lower risk of breast cancer among women with number of pregnancy >2 (OR = 0.79; 95% CI = 0.55–0.97). CT genotype of rs217727 was associated with ER positivity (OR = 2.19; 95 % CI = 1.07–4.45) and HER-2 positivity (OR = 1.34; 95 % CI = 1.05–2.12). It was proved that our results were less likely to be false positives according to false-positive report probability calculation.Our findings extend available data on the association of H19 polymorphisms and BC susceptibility. Further validation in large population or cohort studies is needed.

This study compared the milk protein, fat, lactose, total solids and amino acids (AA) profiles of Murrah buffalo, Nili-Ravi buffalo and crossbreed buffalo. Buffalo milk samples of Murrah (n ¼ 25), Nili-Ravi (n ¼ 20) and Triple-crossbred (n ¼ 23) were collected and milk protein, fat, lactose, total solids and 17 AA profiles were determined. Milk protein and total solids contents of Murrah buffalo were higher than those of Nili-Ravi buffalo (p < .05). The average milk protein, fat, lactose and total solids contents of all buffalo samples were 4.76, 7.31, 5.19 and 18.40 g/100 g of milk, respectively. The AA composition of all three kinds of milk samples was rich in glutamic acid (0.89-0.96 g/100 g of milk) and poor in cysteine (0.01-0.02 g/100 g of milk). Leucine, lysine, valine and isoleucine were the most prevalent essential amino acids; while glutamic acid, proline, aspartic acid and serine were the most prevalent non-essential amino acids in the three kinds of milk samples. Significant differences (p < .05) were observed for concentrations of Lys, Ile, Leu, Phe, Cys and His, while the other 11 amino acids had no significant differences (p > .05). Conclusively, the milk of Murrah buffalo, Nili-Ravi buffalo and crossbreed buffalo was all rich in glutamic acid while poor in cysteine contents. After crossbreeding, the milk production of Triplecrossbred buffalo was higher than the local Chinese buffalo and its milk composition was in between those of Murrah and Nili-Ravi.

Identifying predictive biomarkers for colorectal cancer would facilitate diagnosis and treatment of the disease. This study aimed to investigate the association of the serological biomarkers CEA, CA19-9, CA125, CYFRA21-1 and CA72-4 with patient characteristics and disease outcomes in colorectal cancer. Patients (N = 373) with colorectal cancer were evaluated for the association of CEA, CA19-9, CA125, CYFRA21-1, and CA72-4 pre and post-surgery and at disease recurrence with demographics, disease characteristics including pathological types, degree of differentiation, invasion depth, abdominal lymph node metastasis, TMN stage, Dukes stage, location of cancer and metastasis, and disease outcomes. It was more common for a patient to express these markers prior to surgery and at disease recurrence than following surgery. Overall, the serum levels of CEA, CA19-9, CA125, CYFRA21-1, and CA72-4 were not associated with age, gender, pathological type and location of cancer (all P-values >0.05), but were associated with the poor tumor differentiation, higher tumor invasion, greater degree of abdominal lymph node metastasis, and higher TNM and Duke stage tumors (all P-values < 0.01). CEA expression was associated with older ages (median age 65 years). Multivariate analysis indicated that CEA was correlated with overall survival and none of the markers correlated with disease recurrence. The expression of CEA, CA19-9, CA125, CYFRA21-1, and CA72-4 was associated with specific disease characteristics which tended to indicated more advanced disease and disease recurrence consistent with these biomarkers being useful for detecting colorectal cancer.
