Exploratory biomarker analysis from a phase II clinical trial of eribulin plus gemcitabine versus paclitaxel plus gemcitabine for HER2-negative metastatic breast cancer patients (KCSG BR13-11).
We conduct exploratory biomarker study of a phase II clinical trial of eribulin plus gemcitabine (EG) versus paclitaxel plus gemcitabine (PG) in metastatic breast cancer HER2-negative (BC) patients.We conducted targeted deep sequencing with adjustable cancer gene panel and RNA expression assay. Tumor mutation load (TMB) and mutation signature is determined based on a genetic change in a targeted area. Gene variation analysis performed by PanCancer set Immune Pathway Profiling and PanCancer Panel. Statistical analysis was performed to identify the relationship between genetic changes and clinical outcomes.Of 119 patients, 40 had a biomarker data available.
Among the 40 patients, 4 post-treatment network support them. In targeted sequencing in, FAT3 (48%) is the most frequently mutated gene, followed by PKHD1, TP53, GATA3, PARP4, and PIK3CA. In terms of gene expression, low expression of epithelial-mesenchymal transition (EMT) pathway genes associated with prolonged progression-free survival (PFS) in the group EG, while high expression of EMT pathway is associated with a good prognosis in the PG group. TMB median was 6.5 (range 2.44 to 46.34) and no association between TMB and the patient’s prognosis.
Signature mutation analysis showed that the signature of 3, 20, and 26 which are often observed in our group. Survival analysis Furthermore, according to the signature mutations shows that mutations signature 3, as signature-related deficiencies homologous recombinant, it is strongly associated with disease progression (hazard ratio (log2 scale) 8:21, the 95% confidence interval 2.93 to 13.48 , p = 0.002).
Kaplan-Meier plot also shows that the BCs with signature 3 has a shorter PFS compared with those who did not sign this (median PFS (months) for signing 3 (low vs. high): 17.2 vs. 8.1, p = 0, 0026) .Mutation signature 3, found in about 30% of MBCS regardless of hormone receptor status, was associated with shorter PFS for patients with cytotoxic chemotherapy.

Modifications PARP4, XRCC3, and RAD51 Gene Polymorphism on the relationship between Bisphenol A Exposure and liver abnormalities.
repair genes may play an important role in the relationship between environmental exposures and health outcomes. However, no evidence was available about the effect of genetic polymorphisms on the improvement of the relationship between bisphenol A (BPA) exposure and liver abnormalities.
Therefore, we evaluated the effect of nine polymorphism genotypes in three genes repair, poly (ADP-ribose) member polymerase family of 4 (PARP4), X-ray repair cross-complementary 3 (XRCC3), and RAD51 recombinase (RAD51), in relation between exposure to BPA and heart abnormalities using repeated measures of data for the elderly population.
A significant association between BPA levels and liver abnormalities are found only in elders with PARP4 haplotype GCG, XRCC3 GAG haplotype, or RAD51 TAA haplotype (odds ratio (OR) = 2.16 and p = 0.0014 for PARP4; OR = 1.57 and p = 0.0249 for XRCC3; OR = 1.43 and p = 0.0422 for RAD51). Especially, PARP4 and XRCC3 showed significant interaction with BPA exposure in relation to liver abnormalities (p <0.05 for both genes). These results indicate that PARP4, XRCC3, and RAD51 gene polymorphism has the effect of modifications on the relationship between exposure to BPA and heart abnormalities.
Colorectal neuroendocrine tumors (nets) are rare neoplasms and study of colorectal nets is relatively small compared with other tumors. To better understand the pathogenesis of this tumor, we performed whole genome sequencing and follow-up verification using Sanger sequencing of colorectal and paired Nets para-tumor tissue.
Description: PARP4 encodes poly(ADP-ribosyl)transferase-like 1 protein, which is capable of catalyzing a poly(ADP-ribosyl)ation reaction. Poly [ADP-ribose] polymerase 4 has a catalytic domain which is homologous to that of poly (ADP-ribosyl) transferase, but lacks an N-terminal DNA binding domain which activates the C-terminal catalytic domain of poly (ADP-ribosyl) transferase. Since this protein is not capable of binding DNA directly, its transferase activity may be activated by other factors such as protein-protein interaction mediated by the extensive carboxyl terminus.
