Chronic arsenic exposure and its cancer association is already known. Our study explored the epigenetic
perspectives of arsenic toxicity. The major investigations we performed include DNA damage response,
telomere regulation, arsenic methylation and mitochondrial biogenesis. Our novel findings are to identify
signature patterns for arsenic exposure (compared to those who are unexposed) and arsenic-induced
characteristic lesion (compared to arsenic exposed No Skin Lesion group). Although arsenic induced skin
lesions are hallmarks of arsenic toxicity, it is observed only among15-20% of the exposed population. This
clearly indicates environment and gene crosstalk each other with significant variation at population level.
We have identified alteration in DNA methylation pattern for the candidate genes, histone post translational
modifications and also differential miRNA regulation. Among all different pathways, most critical is the
arsenic metabolism pathway. This metabolism depends on the efficiency of arsenic methylation, which
is further dependant on methylation donor SAM (S-Adenosyl L-methionine) level and enzyme activity of
AS3MT (Arsenite methyltransferase). Our study identified how arsenic depletes SAM level and affect overall
metabolism leading to arsenic susceptibility. Mitochondrial biogenesis also play a significant role, where
regulatory genes including PGC1α, Tfam, NRF1 and NRF2 were upregulated among arsenic induced cancer
patients via promoter hypomethylation. Thus, our study considers a holistic approach to understand the
epigenetic interplay in the individuals having prolonged arsenic exposure history.

Acute left main coronary artery (LMCA) occlusion is a rare clinical presentation which often manifests as a
cardiogenic shock with worse prognosis. However, the clinical outcome depends on the age of the patient,
co-morbidities, the patency and dominancy of Right coronary artery. Since LMCA supplies a large myocardial
territory of left ventricle, it shows a characteristic electrocardiographic (ECG) pattern which helps to an early
diagnosis. Presence of ST elevation in aVR with ST depressions of more than six leads is highly characteristic
for LMCA occlusion. Here we are reporting an extremely rare case of acute concomitant occlusion of LMCA
and Right coronary artery manifesting as a cardiogenic shock with ST elevation in aVR ,V1,III, aVF leads with
ST depressions in all other leads. Patient showed excellent clinical outcome and reversal of characteristic
ECG pattern following percutaneous coronary intervention (PCI) to the culprit vessels.

In home care, the use of oxygen therapy equipment is a determinant in the evolution of chronic patients
who require its application. So far the education that users receive from professionals in charge of
respiratory care regarding the use and its prescription in the home environment, generates good results
compared to control and follow-up with patients; however, when due to clinical and physical conditions it
is time to withdraw oxygen supplies from the home, there is little clarity in the criteria for suspension and
withdrawal of these equipment, generating insecurity in patients and health professionals regarding the
timely withdrawal of oxygen equipment at home, as well as generating unnecessary costs to institutions
providing health services, it also promotes the shortage of oxygen cylinders in situations that are objectively

It has long been documented that abnormal activities of distal cis-regulatory elements such as enhancers
contribute to the intitation and progression of cancer. Recently, super-enhancer hijacking was found to be
esstential for the activation of certain oncogenes. However, the mechanism of action for most tumor-specific
super-enhancers still largely remain elusive. Here, we report that a potential oncogene ETS2 was activated
by a super-enhancer located at its 3’ distal region in colorectal cancer (CRC). The super-enhancer physcially
interacts with ETS2 promoter fragments and is required for transription activation of ETS2. Intriguingly, we
found that a eQTL site for ETS2 resides in this super-enhancer and genetic variation at the SNP potentailly
abolished the binding of a well-known oncogenic trancritpion factor MECOM. Consistently, the expression
of MECOM and ETS2 correlated well with each other in CRC cell lines and multiple CRC datasets and silecning
of MECOM induced downregulation of ETS2. Moreover, the expression of enhancer RNA (eRNA) from the
ETS2 super-enhancer also correlated with the expression of ETS2 in primary CRC samples. Finally, silencing
of both MECOM and ETS2 lead to the inhibition of proliferation, migration and sphere formation of CRC
cells. Taken together, we uncovered a novel MECOM-super enhancer-ETS2 regulatory axis that might be
crucial for activating oncogenic ETS2 in CRC.

Erasure of epigenetic memory is required to convert somatic cells towards pluripotency.
Reactivation of the inactive X chromosome (Xi) has been used to model epigenetic reprogramming in
mouse, but human studies are hampered by Xi epigenetic instability and difficulties in tracking partially
reprogrammed iPSCs. Recently, I have established a cell fusion reprogramming system that recapitulates
features of human naïve pluripotency and enables tracing early chromatin changes. This system revealed
that loss of XIST and H3K27me3 from the human Xi precedes and is required for Xi transcriptional reactivation
ahead of cell division (Cantone et al., Nature Comm 2016). Interestingly, single-cell RNA-FISH and allelespecific
RNA sequencing analyses revealed that reprogramming-mediated human Xi reactivation was partial
and selective for a specific subset of genes. Selective Xi reactivation was not limited to gene loci residing
within specific chromatin domains (e.g. H3K27me3 or H3K9me3 domains) neither influenced by proximity
to XIST locus.
Reactivation was instead associated with stochastic Xi expression ahead of reprogramming, as shown by
single cells and isogenic fibroblast clones (Cantone et al., Genome Biology 2017). Notably, stochastic Xi
transcription is stabilized in some clonal lineages suggesting that single-cell transcriptional variability might
underlie heritable gene reactivation even in heterochromatic contexts. Implications for targeted Xi gene
reactivation during human pluripotent reprogramming and in somatic cells will be discussed as a concept
for modelling and therapy of human X-linked diseases

Objective: To investigate the effect of abnormal liver function on the outcome and safety after transcatheter
aortic valve implantation (TAVI) and whether TAVI is superior to surgical aortic valve replacement (SAVR) in
patients with hepatic insufficiency.
Methods: We searched the databases of PubMed, Embase, the Cochrane Library, Web of Science up to 31
January 2021. Studies to be eligible if mortality after TAVI in patients with and without hepatic insufficiency,
or mortality and complications for TAVI versus SAVR in patients with hepatic insufficiency were reported.
This meta-analysis was registered with PROSPERO (CRD42021247495) and was carried out by using RevMan
5.3 and Stata 14.0.
Results: This meta-analysis of 20 studies assessed a total of 220270 patients. Hepatic insufficiency was
associated with higher short-term mortality [OR=1.88, 95%CI (1.38 to 2.58), P<0.00001] and 1-2 years
mortality [OR=1.64, 95%CI (1.42 to 1.89), P<0.00001]. Between TAVI and SAVR in patients with hepatic
insufficiency, there is statistically significant difference in in-hospital mortality [OR=0.46, 95%CI (0.27 to
0.81), P=0.007], the occurrence rate of blood transfusions [OR=0.34, 95%CI (0.24 to 0.48), P<0.00001) and
the occurrence rate of acute kidney injury [OR=0.55, 95%CI (0.33 to 0.91), P=0.02].
Conclusions: TAVI patients with hepatic insufficiency may have negative impact both on short-term (inhospital
or 30-day) and 1-2-years mortality. For patients with hepatic insufficiency, TAVI could be a better
option than SAVR.

Keynote: Challenges for the empowerment of pregnant women in Primary Health Care in Chile

Time : 9:00 AM

Epigenetics 2021 International Conference Keynote Speaker Maribel Mella Guzmán photo

Maribel Mella Guzman is a Magister in Bioethics and Assistant Professor at the University of Chile with more than 10 years of
experience. She has dedicated herself to the study of the autonomy of women in particular in the period of pregnancy and of gender
violence also in pregnant women.


Primary Health Care (PHC) is the fundamental pillar and gateway of the Chilean Health System. At this
level, the midwife is in charge of people’s Sexual and Reproductive Health. The purpose of this presentation
is to present the role of midwives in PHC in terms of empowering gestational support and the challenges
that this currently presents. Their role is essential in the accompaniment of women and their families since
they are in charge of promoting a healthy pregnancy, prevention and maintenance of healthy lifestyles,
early detection and timely referral of pathologies. The educational and empowering role of this professional
stands out, placing her as a facilitating and empowering figure for women’s autonomy; however, the
challenges she faces are important: to overcome the hegemonic position of the health professional in
order to remedy the state of submission in which pregnant women have been placed, to retake group
education, which has shown better results in terms of empowerment, to incorporate the intersectional view
in order to understand more deeply the differences and particularities of pregnant women, to incorporate
an intercultural perspective that allows immigrant women and women belonging to indigenous peoples to
feel represented and respected in the current health system and finally, to achieve a real communication
and continuity of health care between the primary level (prenatal care) and the tertiary level (delivery care).
