RANKL/RANK/MMP-1 Molecular Triad Contributes to the Metastatic Phenotype of Breast and Prostate Cancer Cells <i>In Vitro</i>
<div><p>The osteolytic nature of bone metastasis results from a tumor-driven increased bone resorption. Bone remodeling is orchestrated by the molecular triad RANK-RANKL-OPG. This process is dysregulated in bone metastases, mostly via induction of RANKL by tumor-derived factors. These factors increase expression of RANKL, which induce osteoclast formation, function, and survival, thereby increasing bone resorption. RANK is unexpectedly expressed by cancer cells, and the activation of RANKL-RANK pathway correlates with an increased invasive phenotype. To investigate the interaction between RANK expression in human breast and prostate cancer cells and their pro-metastatic phenotype we analyzed the activation of RANKL-RANK pathway and its effects on cell migration, invasion, gene expression <i>in vitro</i>, and osteolysis-inducing ability <i>in vivo</i>. RANKL activates kinase signaling pathways, stimulates cell migration, increases cell invasion, and up-regulates MMP-1 expression. <i>In vivo</i>, MMP-1 knockdown resulted in smaller x-ray osteolytic lesions and osteoclastogenesis, and decreased tumor burden. Therefore, RANKL inhibition in bone metastatic disease may decrease the levels of the osteoclastogenesis inducer MMP-1, contributing to a better clinical outcome.</p></div

<p><b>Detection and molecular
characterization of Chikungunya and Zika in a dengue endemic region of the
Peruvian coast</b><b> </b></p>

<p><b>ABSTRACT</b></p>
<p><b>Background:</b> Arboviral diseases has reemerged
in the last years affecting primarily the
coast of Peru. Piura is an endemic region of Dengue, where
the recent appearance of Chikungunya (CHIKV) and Zika (ZIKV) has been renewed.</p>
<p><b>Aim:</b> To assess
the presence of DENV, CHIKV, and ZIKV in
serum samples of patients with acute febrile illness in a locality ofPiura,
Peru and describe associated clinical features.</p>
<p><b>Methodology:</b> Descriptive
cross-sectional study, sampling was done for convenience where it was obtained
atotal of 496 serum samples from patients with acute febrile illness were
collected from 18 primary care centers. All samples were analyzed via real-time
RT-PCR to detect DENV, CHIKV, and ZIKV.
In addition, positive samples for DENV were also processed for serotypes 1 to 4
classification via RT-PCR.</p>
<p><b>Results:</b> DENV was
the most common arbovirus detected in 170/496 (34.3%), followed by ZIKV in
39/496 (7.9%) and CHIKV in 23/496 (4.6%).
Among the 170 samples positive for DENV, serotype 2 was the most
predominant type present in 97/170 (57.1%) of samples, followed by the serotype
3 in 9/170 (5.3%). Headaches, muscle pain,
and joint pain were the most common symptoms associated with fever in patients
with DENV and ZIKV. No symptoms predominance was observed in patients with
CHIKV.</p>
<p><b>Conclusions:</b> </p>
<p>DENV is
considered the most frequent arbovirus in Peru and the number of cases has increased
dramatically in the last 5 years. However, it is not the only arbovirus that
circulates along the northern coast of Peru. It has also been determined the
presence of ZIKV and CHIKV in our population, which may suggest the circulation
of other arboviruses that have not been detected.</p>

<p><b>Frequency and coinfection between genotypes of Human papillomavirus
in a population of asymptomatic women in northern Peru.</b></p><p><b><br></b></p><p></p><p><b>Objective:</b> Describe the prevalence of HPV
genotypes via PCR and DNA sequencing in 397 women who attended to the
gynecological outpatient clinic in the Hospital Regional Docente de Cajamarca from
March to September 2017.</p>
<p><b>Results:</b> A positive PCR result for HPV
was observed in 121 cervical samples. A high-risk genotype was found in 63.6%
(77/121) of patients, a probably oncogenic type in 23.1% (28/121) and a
low-risk type in 7.4%. Among the high-risk genotypes, HPV-31 was the most
common one present in 20% (21/77), followed by HPV-16 in 11.4% (12/77). Coinfections
between two or more genotypes were observed in 12 cases.</p><b></b><p></p
