Abstract
The development of metabolic diseases is linked to the gut microbiota. A cross-sectional study involving 45 children (6 to 12 years old) was conducted to investigate the relationship between gut microbiota and childhood obesity. Anthropometric and metabolic measurements, food-frequency questionnaires (FFQs), and feces samples were obtained. Using the body mass index (BMI) z-score, we categorized each participant as normal weight (NW), or overweight and obese (OWOB). We determined 2 dietary profiles: one with complex carbohydrates and proteins (pattern 1), and the other with saturated fat and simple carbohydrates (pattern 2). The microbial taxonomic diversity and metabolic capacity were determined using shotgun metagenomics. We found differences between both BMI groups diversity. Taxa contributing to this difference, included Eubacterium sp., Faecalibacterium prausnitzii, Dialister, Monoglobus pectinilyticus, Bifidobacterium pseudocatenulatum, Intestinibacter bartlettii, Bacteroides intestinalis, Bacteroides uniformis, and Methanobrevibacter smithii. Metabolic capacity differences found between NW and OWOB, included the amino acid biosynthesis pathway, the cofactor, carrier, and vitamin biosynthesis pathway, the nucleoside and nucleotide biosynthesis and degradation pathways, the carbohydrate-sugar degradation pathway, and the amine and polyamine biosynthesis pathway. We found significant associations between taxa such as Ruminococcus, Mitsuokella multacida, Klebsiella variicola, and Citrobacter spp., metabolic pathways with the anthropometric, metabolic, and dietary data. We also found the microbiome's lipooligosaccharide (LOS) category as differentially abundant between BMI groups. Metabolic variations emerge during childhood as a result of complex nutritional and microbial interactions, which should be explained in order to prevent metabolic illnesses in adolescence and maturity. IMPORTANCE The alteration of gut microbiome composition has been commonly observed in diseases involving inflammation, such as obesity and metabolic impairment. Inflammatory host response in the gut can be a consequence of dietary driven dysbiosis. This response is conducive to blooms of particular bacterial species, adequate to survive in an inflammatory environment by means of genetical capability of utilizing alternative nutrients. Understanding the genomic and metabolic contribution of microbiota to inflammation, including virulence factor prevalence and functional potential, will contribute to identifying modifiable early life exposures and preventive strategies associated with obesity risk in childhood.

Abstract
The aim is to determine the prevalence of active infection by herpes simplex virus type 2 (HSV-2) among Mexican women with high-risk human papillomavirus (HR-HPV) cervical infection, recruited from public gynecology and colposcopy services. In a cross-sectional study, HSV-2 antibodies, HSV-2 DNA, and HR-HPV DNA were quantified. Significant differences in HSV-2 seroprevalence and HSV-2 active infection rates were found between negative and positive HR-HPV cases. HSV-2 seroprevalence was 28.15% and 16.1% (P = .0001), while HSV-2 active infection rates were 6.83% and 0.62% (P = .001) for positive and negative HR-HPV groups, respectively. The risk of HSV-2 seropositivity was 1.7 times greater for HR-HPV-positive cases (P = .02). Similarly, HR-HPV-positive cases were nine times more likely to have an HSV-2 active infection than HR-HPV-negative cases (P = .03). High HSV-2/h-HPV coinfection rates were observed among women recruited from public gynecology and colposcopy services. The main factors related to an HSV-2 active infection are a history of risky sexual behavior and HR-HPV infection. The prevalence of HSV-2 active infection among positive HR-HPV subjects indicate that these infections constitute an important group of STIs in Mexico.

Abstract
Glioblastoma multiforme (GBM) is one of the most aggressive astrocytic tumors; it is resistant to most chemotherapeutic agents currently available and is associated with a poor patient survival. Thus, the development of new anticancer compounds is urgently required. Herein, we studied the molecular mechanisms of cell death induced by the experimental drugs resveratrol and MG132 or the antineoplastic drugs cisplatin and etoposide on a human GBM cell line (D54) and on primary cultured mouse astrocytes (PCMAs). Caspases, Bcl-2, inhibitors of apoptosis proteins (IAP) family members, and p53 were identified as potential molecular targets for these drugs. All drugs had a cytotoxic effect on D54 cells and PCMAs, with a similar inhibitory concentration (IC50) after 24 h. However, MG132 and cisplatin were more effective to induce apoptosis and autophagy than resveratrol and etoposide. Cell death by apoptosis involved the activation of caspases-3/7, -8, and -9, increased lysosomal permeability, LC3 lipidation, poly-(ADP-ribose) polymerase (PARP)-1 fragmentation, and a differential expression of genes related with apoptosis and autophagy like Mcl-1, Survivin, Noxa, LC3, and Beclin. In addition, apoptosis activation was partially dependent on p53 activation. Since experimental and antineoplastic drugs yielded similar results, further work is required to justify their use in clinical protocols.

Abstract
Cervical cancer (CC) is responsible for >260,000 deaths worldwide each year. Efforts are being focused on identifying genetic susceptibility factors, especially in genes related to the immune response. Akna has been proposed to be one of them, but data regarding its functional role in the disease is scarce. Supporting the notion of akna as a CC susceptibility gene, we found two polymorphisms associated with squamous intraepithelial lesion (SIL) and CC; moreover, we identified an association between high akna expression levels and CC and SIL, but its direction differs in each disease stage. To show the potential existence of a cis-acting polymorphism, we assessed akna allelic expression imbalance for the alleles of the -1372C>A polymorphism. We found that, regardless of the study group, the number of transcripts derived from the A allele was significantly higher than those from the C allele. Our results support the hypothesis that akna is a CC susceptibility genetic factor and suggest that akna transcriptional regulation has a role in the disease. We anticipate our study to be a starting point for in vitro evaluation of akna transcriptional regulation and for the identification of transcription factors and cis-elements regulating AKNA function that are involved in carcinogenesis.

Identification of novel variants of interferon-tau gene in Bighorn sheep ( Ovis canadensis mexicana ), Pelibuey sheep ( Ovis aries ) and its expression in hybrid blastocysts ( Ovis canadensis×Ovis aries ). Can. J. Anim. Sci. 92: 275–283. The major signal for maternal recognition of pregnancy (MRP) in ruminants is interferon-tau (IFNT). Four novel sequences of the IFNT gene were isolated from genomic DNA obtained from blood samples of Bighorn, Pelibuey or the hybrid ewes. The deduced amino acid sequence of the hybrid ewe showed 100% identity with one Bighorn sheep IFNT sequence, suggesting that this sequence was inherited from Bighorn sheep. The high degree of identity between Pelibuey and Bighorn sheep sequences could be a possible explanation for the successful MRP in some Bighorn hybrid pregnancies. In vivo and in vitro domestic sheep (Ovis aries) and hybrid sheep (Ovis aries×Ovis canadensis) blastocysts were obtained, and IFNT expression was measured by semiquantitative RT-PCR. In vivo and in vitro hybrid blastocysts showed lower expression of IFNT when compared with domestic blastocysts. In conclusion this study showed that there exists an effect of hybridization on IFNT expression and this can affect the MRP.

Abstract
Cervical cancer (CC) constitutes a major women health problem. Clinical, molecular, and epidemiological investigations have identified persistent infection with high risk human papillomavirus (HR-HPV) as the major cause of CC. HR-HPVs lead to development of cervical carcinoma, predominantly through the action of E5, E6 and E7 viral oncoproteins. After HR-HPV infection, viral proteins employ strategies to modulate apoptosis. The E2 viral protein induces apoptosis in both normal and HPV-transformed cells through activation of caspase-8. The E5 protein can impair CD95L- and TRAIL-mediated apoptosis, which suggests that it may prevent apoptosis at early stages of viral infection. E6 inhibits apoptosis through the proteolytic inactivation of pro-apoptotic proteins such as p53, FADD, or procaspase-8, employing the ubiquitin proteasome pathway, or through interactions with proteins that form the death-inducing signaling complex (DISC) such as TNF-R1. On the other hand, E7 oncoprotein expressing cells are usually predisposed to undergo apoptosis. Useful targets for therapeutic strategies would interfere with expression or function of HR-HPV proteins to eliminate cells that express viral oncoproteins. In this review, we summarize the available data on the interaction of early HPV proteins with cellular factors that promote cell death, and the functional consequences of these interactions on apoptosis.

Abstract
Transforming growth factor beta-1 (TGF-beta 1) is produced by several cell lineages such as lymphocytes, macrophages, and dendritic cells, and its expression serves in both autocrine and paracrine modes to control the differentiation, proliferation, and state of activation of these and other cells. In general, TGF-beta 1 has pleiotropic properties on the immune response during the development of infection diseases and cancer; however, the mechanisms of action and regulation of gene expression of this cytokine are poorly understood, in this review, the biological properties and the molecular mechanisms that regulate TGF-beta 1 gene expression are described, to understand the role of this cytokine in growth and cell differentiation. The knowledge of molecular mechanisms of gene expression of TGF-beta 1 may serve to develop new cancer therapies.
