Metformin is most widely prescribed for type 2 diabetes. Recently, evidences have shown that metformin has anticancer effects on pancreatic-, colorectal-, ovarian-, and other cancers. Because metformin has less adverse effects and is inexpensive, it could be a useful chemo-therapeutic agent with anticancer effects. In this study, we demonstrated metformin inhibited by cell proliferation, cell migration ability, clonogenic ability, and cancer stem cell population. Metformin also induced cell cycle arrest in parental-(SNU-C5), and 5-Fu resistant-colorectal cancer cell line (SNU-C5_5FuR)...

Rigorous research on the efficacy of family group conferencing is rare. This randomized control trial study used an intent-to-treat approach to examine whether a referral to a family group conference (FGC) was associated with re-referrals, substantiated re-referrals, or out-of-home placements among child welfare-involved families receiving in-home services. We found no significant associations between treatment and control group assignment and the three outcomes for the sample as a whole. However, families with more children had higher odds of a re-referral and a substantiated re-referral, families with more than one parent had higher odds of re-referral, and families where a substance abuse services referral was noted had higher odds of out-of-home placement...

Maize is an important food crop and industrial material owing to its high starch content. However, the mechanism of starch synthesis is not fully elucidated, especially with regard to the expression and regulation of starch synthetic genes. The APETALA2/Ethylene Responsive Factor (AP2/ERF) family plays a crucial role in various biological processes via regulating gene expression. In this study, the ZmEREB94 gene was identified through co-expression analysis. Bioinformatics analysis confirmed that ZmEREB94 belongs to the AP2/ERF family...

Cell death-inducing DFF45-like effector (CIDE) B is a member of the CIDE family of apoptosis-inducing factors. In the present study, we detected a single nucleotide polymorphism (SNP), c.414G>A, which corresponds to the synonymous SNP 414Arg, in CIDE-B in the Berkshire pigs. We also analyzed the relationships between the CIDE-B SNP and various meat quality traits. The SNP was significantly associated with post-mortem pH24h, water-holding capacity (WHC), fat content, protein content, drip loss, post-mortem temperature at 12 h (T12) and 24 h (T24) in a co-dominant model (P < 0...

Objectives: The role of family relationships in the lives of older adults has received substantial attention in recent decades. Scholars have increasingly looked beyond simple models of family relations to approaches that recognize the complex and sometimes contradictory nature of these ties. One of the most exciting conceptual and methodological developments is the application of within-family differences approaches. In this paper, we focus on the ways in which such within-family approaches can extend the understanding of patterns and consequences of intergenerational ties in adulthood...

The present study examined whether parental involvement in their adolescents' lives is associated with adolescent smoking in a vocational school setting when controlling for socioeconomic background and parental smoking. The study was conducted in spring 2013 and involved 34 776 Finnish vocational school students (mean age 17.6 years). The data were analyzed using multinomial regression. The results showed that lower parental involvement was significantly associated with adolescent daily smoking in both genders and with occasional smoking in girls...

Myosin Ic is thought to be the principal constituent of the motor that adjusts mechanical responsiveness during adaptation to prolonged stimuli by hair cells, the sensory receptors of the inner ear. In this context myosin molecules operate neither as filaments, as occurs in muscles, nor as single or few molecules, as characterizes intracellular transport. Instead, myosin Ic molecules occur in a complex cluster in which they may exhibit cooperative properties. To better understand the motor's remarkable function, we introduce a theoretical description of myosin Ic's chemomechanical cycle based on experimental data from recent single-molecule studies...

Lipoprotein lipase (LPL) is widely expressed in skeletal muscles, cardiac muscles as well as adipose tissue and involved in the catabolism of triglyceride. Herein we have systematically characterized two novel loss-of-function mutations in LPL from a Chinese family in which afflicted members were manifested by severe hypertriglyceridemia and recurrent pancreatitis. DNA sequencing revealed that the proband was a heterozygote carrying a novel c.T928C (p.C310R) mutation in exon 6 of the LPL gene. Another member of the family was detected to be a compound heterozygote who along with the c...

IKBKE is increased in several types of cancers and is associated with tumour malignancy. In this study, we confirmed that IKBKE promoted glioma proliferation, migration and invasion in vitro. Then, we further discovered that IKBKE increased Yes-associated protein 1 (YAP1) and TEA domain family member 2 (TEAD2), two important Hippo pathway downstream factors, to induce an epithelial-mesenchymal transition (EMT), thus contributing to tumour invasion and metastasis. We also testified that YAP1 and TEAD2 promoted epithelial-mesenchymal transition (EMT) in malignant glioma...

My laboratory investigations have been driven by an abiding interest in understanding the consequences of genetic rearrangement in evolution and disease, and in using viruses to elucidate fundamental mechanisms in biology. Starting with bacteriophages and moving to the retroviruses, my use of the tools of genetics, molecular biology, biochemistry, and biophysics has spanned more than half a century-from the time when DNA structure was just discovered to the present day of big data and epigenetics. Both riding and contributing to the successive waves of technology, my laboratory has elucidated fundamental mechanisms in DNA replication, repair, and recombination...

Although ibrutinib is highly effective in Waldenstrom macroglobulinemia (WM), no complete remissions in WM patients treated with ibrutinib have been reported to date. Moreover, ibrutinib-resistant disease is being steadily reported and is associated with dismal clinical outcome (overall survival of 2.9-3.1 months). To understand mechanisms of ibrutinib resistance in WM, we established ibrutinib-resistant in vitro models using validated WM cell lines. Characterization of these models revealed the absence of BTK(C481S) and CXCR4(WHIM-like) mutations...

Asthenozoospermia (AZS) is a common cause of male infertility, characterized by abnormal reduction in the motility of ejaculated spermatozoa. Here, in a patient from a consanguineous family, we identified a homozygous mutation (c.G4343A, p.R1448Q) in SPAG17 by whole-exome sequencing. The encoded protein, SPAG17, localizes to the axonemal central apparatus and is considered essential for flagellar waveform. In silico analysis revealed that R1448Q is a potential pathogenic mutation. Immunostaining and western blot assays showed that the R1448Q mutation may exert a negative effect on the steady-state of the SPAG17 protein...

Vitamin D requires a two-step activation by hydroxylation: the first step is catalyzed by hepatic 25-hydroxylase (CYP2R1, 11p15.2), and the second one is catalyzed by renal 1α-hydroxylase (CYP27B1, 12q13.1), which produces the active hormonal form of 1,25-(OH)2 D. Mutations of CYP2R1 have been associated with Vitamin D-dependent rickets type 1B (VDDR1B), a very rare condition that has only been reported to affect 4 families to date. We describe 7 patients from two unrelated families who presented with homozygous loss-of-function mutations of CYP2R1...

Forkhead box R2 (FOXR2), a member of the FOX gene family, has not been very well investigated for its role in cancer. A recent study has shown that FOXR2 is highly expressed in breast cancer samples and is associated with poor prognosis. In addition, FOXR2 was identified as an oncogene in medulloblastoma. Nevertheless, whether FOXR2 plays a role in colorectal cancer (CRC) remains unclear. In the present study, we conducted several in vitro and in vivo studies to investigate the expression and effect of FOXR2 in CRC...
