Int J Biol Macromol 2024; 270:132347. [PMID: 38754673 DOI: 10.1016/j.ijbiomac.2024.132347] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 05/06/2024] [Accepted: 05/11/2024] [Indexed: 05/18/2024]
Abstract
Aberrant cell proliferation is one of the main characteristics of tumor cells that can be affected by many cellular processes and signaling pathways. Kinesin superfamily proteins (KIFs) are motor proteins that are involved in cytoplasmic transportations and chromosomal segregation during cell proliferation. Therefore, regulation of the KIF functions as vital factors in chromosomal stability is necessary to maintain normal cellular homeostasis and proliferation. KIF deregulations have been reported in various cancers. MicroRNAs (miRNAs) and signaling pathways are important regulators of KIF proteins. MiRNAs have key roles in regulation of the cell proliferation, migration, and apoptosis. In the present review, we discussed the role of miRNAs in tumor biology through the regulation of KIF proteins. It has been shown that miRNAs have mainly a tumor suppressor function via the KIF targeting. This review can be an effective step to introduce the miRNAs/KIFs axis as a probable therapeutic target in tumor cells.

Divya KT, Chidrawar VR, Bhupalam PK, Shiromwar S, Aljameeli AM, Vyshnavi G, Reddama IS, Boreddy V. Assessment of knowledge and attitude of cervical cancer among the youths in the Rayalaseema region of Andhra Pradesh - India. JOURNAL OF EDUCATION AND HEALTH PROMOTION 2024; 13:73. [PMID: 38559478 PMCID: PMC10979777 DOI: 10.4103/jehp.jehp_318_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/05/2023] [Accepted: 08/30/2023] [Indexed: 04/04/2024]
Abstract
BACKGROUND India suffers a quarter of the global burden of cervical cancer (CC) but is controllable by taking some precautions. The major issue is the low amount of participation among women in screening and vaccination for disease. The objective of the research is to evaluate knowledge, attitude, and practice (KAP) regarding CC among college going students residing in the Rayalaseema region of Andhra Pradesh-India. MATERIAL AND METHODS A cross-sectional study was conducted on a total of 380 subjects whose ages ranged from 15 to 25 and older. The questionnaires were circulated through google forms. The socio-demographic variables and KAP levels are represented by descriptive statistics. The Chi-square test is used to determine the relationship between sociodemographic factors and KAP levels. RESULTS Among 380 subjects, 172 (54.7%) are aware of CC, 71% have poor knowledge, and 20% have good knowledge about CC. More than three-fourths of women 374 (98.4%) are not having regular practice towards CC. CONCLUSION The awareness about CC is very low in the population, so prevention of CC relies on routine screening, proper vaccination, and treatment. Awareness programs and promoting knowledge about cervical health in social media are required.

Abstract
INTRODUCTION Cervical cancer has been considered as one of the most common cancers in women (15-44 years) globally, but the advent of the human papilloma virus (HPV) vaccine has raised the anticipation that eradication of cervical carcinoma might be achieved in the near future as several prophylactic cervical carcinoma vaccines have already been currently licensed in various countries. Countries should devise strategies, practices and policies to attain and sustain higher levels of HPV immunization coverage as still 68% countries have introduced HPV vaccine in their national immunization programs even after 17 years following the licensure of the first prophylactic HPV vaccine. METHODOLOGY A comprehensive literature analysis was conducted using various databases and search engines, to include the most relevant research articles and data available and critically discussed the operational gaps that need to be answered to achieve adequate coverage of HPV vaccination. RESULTS The present review highlights the existing HPV vaccination strategies, unmet needs and challenges needed to be addressed for proper implementation framework as well as the collaborations required to achieve decent vaccination coverage. Well-coordinated vaccination strategy with focus on adolescent girls and if possible, boys can lead to dramatic impact on disease reduction around the world.

Abstract
The main objective of this study is to screen potential small molecule inhibitors against HPV (Human Papilloma Virus)-16 E6 protein (HPV16 E6P) using a fragment-based approach. Twenty-six natural HPV inhibitors were selected based on the review of the literature. Among them, Luteolin was selected as the reference compound. These 26 compounds were used to generate novel inhibitors against HPV16 E6P. Fragment script and BREED of Schrodinger software were used to build novel inhibitor molecules. The result in 817 novel molecules was docked into the active binding site of HPV E6 protein and the top ten compounds were screened based on binding affinity compared to Luteolin for further study. Compounds Cpd5, Cpd7, and Cpd10 were the most potent inhibitors of HPV16 E6P and these were non-toxic and showed high Gastrointestinal (GI) absorption and positive drug-likeness score. Complexes of these compounds were stable in the 200 ns Molecular Dynamics (MD) simulation. These 3 HPV16 E6P inhibitors could be the lead molecules as new drugs for HPV-related diseases.Communicated by Ramaswamy H. Sarma.

Abstract
Purpose The objective of this research project was to estimate DNA damage in patients diagnosed with cervical cancer using the comet assay, establish a correlation between this quantification and the oxidative stress marker malondialdehyde (MDA; plasma MDA), and compare the resulting parameters between the cases and age-matched controls. Materials and methods This study included 49 cervical cancer cases and 49 age-matched controls to measure DNA damage parameters such as comet length, head diameter, percentage of DNA in the comet head, tail length, percentage of DNA in the comet tail, and oxidative stress marker (plasma MDA) using the thiobarbituric acid reactive substance (TBARS) enzyme-linked immunosorbent assay (ELISA) method. Results Comet metrics suggesting DNA damage, such as comet length, tail length, and percentage of DNA in the comet tail, were considerably higher in cervical cancer cases than in age-matched controls. The proportion of DNA in the comet head, representing undamaged/mild DNA damage, was significantly higher in age-matched controls than in cervical cancer patients. Plasma MDA and comet tail length were shown to have a positive correlation. Compared to the age-matched controls, those between the ages of 30 and 39, with a parity of two to four, who had a history of early age at first pregnancy and a positive family history of cervical cancer, had the highest level of DNA damage. Conclusion The elevated levels of comet parameters and their positive correlation with plasma MDA suggest that individuals diagnosed with cervical cancer have a higher degree of DNA damage compared to the control group. In conjunction with established methods like the PAP smear, this predictive test comprising comet assay and estimation of plasma MDA may be utilized to identify and assess the risk of cervical cancer in individuals aged 30-39 years, with a parity between two and four pregnancies and a prior history of early age at first pregnancy, accompanied by a positive family history of the disease.

Abstract
Cervical cancer is one of the most common cancers in women aged 15-44 years in the world, with more than three-quarters of cases diagnosed at a locally advanced clinical stage with minor prospects of survival. Although only a small percentage of women with Human Papilloma Virus (HPV) develop cervical cancer and most of the HPV infections are cleared subsequently at primary stage itself, but seroconversion not always guarantees that the individual is immune to HPV. The advent of the cervical carcinoma vaccine has raised the expectations that eradication of cervical carcinoma might be possible in the near future as it exhibited remarkably high efficacy against the vaccine-specific types in naive women with no serious vaccine-related adverse events. Few prophylactic HPV vaccines are currently licensed in over 100 countries. It has also been suggested that vaccinating both men and women is more beneficial than vaccinating only females. Vaccination is a cost-effective strategy to reduce the incidence of cervical cancer and mortality compared to no vaccination based on the cost of cancer treatment. Well-coordinated vaccination strategy with focus on adolescent girls and if possible, boys can lead to dramatic impact on disease reduction around the world.

Abstract
Emerging diseases are infectious diseases that pose significant threat to human health, causing millions of deaths and disabilities in the upcoming days. Periodic epidemics of new infections and old reinfections increase the global burden of disease prevalence. They can be caused by new pathogens or evolving ones, which change human behavior and environmental factors. Researchers have studied the dynamic connections between microbes, hosts, and the environment, but new infectious diseases like coronavirus disease 2019 (COVID-19), re-emerging diseases, and deliberately disseminated diseases persist despite earlier hopes of elimination. With heavy privatesector investments, Indian pharmacology now provides core Expanded Programme on Immunization vaccines to United Nations International Children's Emergency Fund, producing previously unattainable vaccines for diseases like meningitis, hepatitis B, pneumococcal conjugate, rotavirus, influenza A (H1N1), and COVID-19. India's vaccine sector has emerged, among the oriented leaders of the Bharat Biotech, Serum Institute of India, Panacea Biotech and Biological E. Specifically, the technology transferred from Western countries has benefited the sector, which produces 1.3 billion doses annually. The Serum Institute is the world's largest manufacturer of vaccines, providing measles and diphtheria-tetanus-pertussis vaccines to United Nations. The Serum Institute has developed several vaccines, including Nasovac, MenAfriVac, Pentavac, and an inactivated polio vaccine. India's success in vaccinations can be attributed to attractive investment conditions, government assistance, international alliances, and rising domestic technical talent. Despite its booming economy and technical advances, India's disproportionate share of the world's child mortality rate remains unchanged. However, the growing production and distribution of vaccinations in developing nations has initiated a new era, leading to a worldwide decline in childhood death and disease.

Abstract
Long non-coding RNAs (lncRNAs) have emerged as auxiliary regulators of gene expression influencing tumor microenvironment, metastasis and radio-resistance in cancer. The presence of lncRNA in extracellular fluids makes them promising diagnostic markers. LncRNAs deploy higher-order structures to facilitate a complex range of functions. Among such structures, G-quadruplexes (G4s) can be detected or targeted by small molecular probes to drive theranostic applications. The in vitro identification of G4 formation in lncRNAs can be a tedious and expensive proposition. Bioinformatics-driven strategies can provide comprehensive and economic alternatives in conjunction with suitable experimental validation. We propose a pipeline to identify G4-forming sequences, protein partners and biological functions associated with dysregulated lncRNAs in cervical cancer. We identified 17 lncRNA clusters which possess transcripts that can fold into a G4 structure. We confirmed in vitro G4 formation in the four biologically active isoforms of SNHG20, MEG3, CRNDE and LINP1 by Circular Dichroism spectroscopy and Thioflavin-T-assisted fluorescence spectroscopy and reverse-transcriptase stop assay. Gene expression data demonstrated that these four lncRNAs can be potential prognostic biomarkers of cervical cancer. Two approaches were employed for identifying G4 specific protein partners for these lncRNAs and FMR2 was a potential interacting partner for all four clusters. We report a detailed investigation of G4 formation in lncRNAs that are dysregulated in cervical cancer. LncRNAs MEG3, CRNDE, LINP1 and SNHG20 are shown to influence cervical cancer progression and we report G4 specific protein partners for these lncRNAs. The protein partners and G4s predicted in lncRNAs can be exploited for theranostic objectives.

Abstract
Introduction Cervical cancer is one of the leading causes of morbidity and mortality among women globally as well as in Nepal. It is attributable to persistent infection by high-risk human papillomavirus, especially human papillomavirus-16 and human papillomavirus-18. The aim of this study was to find out the knowledge of cervical cancer screening and prevention by human papillomavirus deoxyribonucleic acid and human papillomavirus vaccination among women attending a tertiary care centre. Methods A descriptive cross-sectional study was conducted in patients attending the outpatient Department of Gynaecology in a tertiary care centre from 18 March to 30 April 2023. After calculating sample size and taking a convenience sampling a survey questionnaire on knowledge of Cervical Cancer Screening and Prevention by Human Papillomavirus Deoxyribonucleic Acid and Human Papillomavirus Vaccination was collected. The point estimate was calculated at a 95% confidence interval. Results Among 508 women, 42 (8.25%) (5.86-10.64, 95% Confidence Interval) had knowledge of cervical cancer screening and prevention by human papillomavirus deoxyribonucleic acid and human papillomavirus vaccination. According to the questionnaires with a total sample of 508, 164 (32.28%) know about cervical cancer, 15 (2.95%) know about HPV infection, 14 (2.76%) know about HPV infection causes cervical cancer, and 21 (4.13%) know about HPV transmitted through multiple sex partners. Conclusions The knowledge of cervical cancer screening and prevention by human papillomavirus deoxyribonucleic acid and human papillomavirus vaccination among women is very low. This study recommends having a health education and awareness programme on it to increase knowledge. Keywords cervical cancer; human papillomavirus; pap smear; sexual intercourse; vaccination.

[PMID: 37215327 PMCID: PMC10198780 DOI: 10.3389/frph.2023.1151179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 04/12/2023] [Indexed: 05/24/2023] Open
Abstract
Background The HPV vaccine is used as one of the main prevention tools for HPV-related cancers globally, yet it is not part of the Indian National Immunization program. In light of the introduction of the indigenous vaccine, we examine the effectiveness of health education about uptake, acceptance, and awareness. Methods Research was performed in the following databases: PubMed, CINAHL, Scopus, and Embase to identify studies between 2008 and 2022. Studies were included if: they were conducted in India including primary data research and health education intervention, and participants were between 9 and 29 years old. Results Out of the 10.952 results, 7 studies were included. Four studies focused on adolescent girls, aged from 9 to 20 years old, and 3 on university students aged from 17 to 26 years. Five studies were implemented in urban areas and 2 in rural areas. Health education interventions proved to be effective in increasing uptake, awareness, and acceptance of the HPV vaccine. The barriers included among others: cost, lack of awareness, and cultural barriers. Conclusion Observations from this study outline immediate action for policymakers to educate and encourage the young population toward HPV vaccination. Future programs should be aimed at different population groups and be adjusted according to their special characteristics and needs. Attention should be given to the male population and marginalized groups. The involvement of various stakeholders proved to be beneficial, and it is highly recommended.

Abstract
Breast carcinoma is now the most common cancer in the world. In view of its high mortality, there is a need to identify new prognostic biomarkers. Both IMP3 and SLUG have been implicated in cancer metastasis. This was a retrospective study conducted on 60 breast carcinoma cases using tissue microarrays. Demographic and clinicopathological details were recorded. Immunohistochemistry for IMP3 and SLUG was performed and evaluated in terms of percentage-cell-positivity and intensity of staining. A proforma was used to store data and was analyzed using SPSS v20. IMP3 positivity was found in 87% breast carcinoma cases and was significantly associated with tumor size (p = 0.03) and TNM stage (p = 0.024). IMP3 staining intensity showed significant association with histological grade (p = 0.009), TNM stage (p = 0.036), and molecular subtype (p = 0.03). SLUG immunoexpression was seen in 90% breast carcinoma cases and was significantly associated with TNM stage (p = 0.006). SLUG staining intensity was significantly associated with age (p = 0.025) and TNM stage (p = 0.004). IMP3 and SLUG immunopositivity and their staining intensities were significantly associated (p <0.001, p <0.001). IMP3 and SLUG percentage cell positivities were also significantly correlated (p <0.001). IMP3 and SLUG are, thus, poor prognostic markers with a role in tumor invasiveness and aggressiveness via epithelial-mesenchymal transition. Hence, IMP3 and SLUG-based targeted therapies may be useful in the treatment of breast carcinoma.

Abstract
BACKGROUND Cervical cancer is one of the leading causes of female death, with a mortality rate of over 200,000 per year in developing countries. Despite a decrease in cervical cancer occurrences in developed countries over the last decade, the frequency of the disease in developing nations continues to rise at an alarming rate, particularly when it is linked to the human papillomavirus (HPV). With just a few highly invasive conventional therapies available, there is a clear need for novel treatment options such as nanotechnology-based chemotherapeutic drug delivery. METHODS Traditional anticancer therapy is limited by poor drug potency, non-specificity, unwanted side effects, and the development of multiple drug resistance (MDR), leading to a decrease in long-term anticancer therapeutic efficacy. An ideal cancer therapy requires a personalized and specialized medication delivery method capable of eradicating even the last cancer cell responsible for disease recurrence. RESULTS Nanotechnology provides effective drug delivery mechanisms, allowing it to serve both therapeutic and diagnostic purposes. Nanotechnology-based formulations are widely used to accurately target the target organ, maintain drug load bioactivity, preferentially accumulate the drug at the target location, and reduce cytotoxicity. CONCLUSION The key benefits of this drug delivery are that it improves pharmacological activity, solubility, and bioavailability and reduces toxicity in the target tissue by targeting ligands, allowing for new innovative treatment methods in an area that is desperately required. The goal of this review is to highlight possible research on nanotechnologybased delivery systems for cancer detection and treatment.

Abstract
Priya GaneshkumarObjectives We evaluated the impact of a standardized, simple audio-visual (AV) training video developed in regional languages on cervical cancer awareness among apparently healthy women and their willingness to undergo regular cervical cancer screening. Materials and Methods This cross-sectional noninterventional multicentric survey was conducted in 69 centers across 14 states in India and one center in UAE among women aged between 18 and 88 years attending clinics for a variety of indications. Using a short questionnaire, cervical cancer awareness and willingness to undergo cervical cancer screening were assessed before and after the AV training. Statistical Analysis In addition to descriptive analysis, improvement in awareness after the AV training was assessed using McNemar's test, and comparison of responses between subgroups was performed using Pearson chi-squared test. Results The survey was completed by 3,188 apparently healthy women (mean age: 36.8 ± 11.3 years). Before AV training, correct answers were given to only 4/6 questions by majority of the participants; most participants were unaware about the main cause of cervical cancer (1,637/3,188, 51.4%), availability of cervical cancer screening tests (1,601/3,188, 50.2%), and cervical cancer vaccines (1,742/3,188, 54.6%). Only 576 women (18.1%) had undergone cervical cancer screening in the past. After the AV training, the proportion of women correctly responding to all six questions improved significantly (p < 0.05), and 84.4% (2691/3188) women showed willingness to undergo periodic cervical cancer screening. Compared to unmarried and professional women, although married women and home-makers had lower awareness scores, the latter subgroups had more often undergone previous cervical cancer screening. Conclusion It is possible to improve cervical cancer awareness among healthy women, and to enhance their willingness to undergo regular cervical cancer screening tests using a simple, six minute-long, standardized AV training material.

Abstract
Human papilloma virus (HPV), one of the most common sexually transmitted infections, plays a pivotal role in head and neck cancer, primarily oral and oropharyngeal squamous cell carcinomas. HPV is a vaccine-preventable disease that also contributes to cervical cancer. Although HPV vaccination effectively protects the individual against all HPV-associated human carcinomas, the awareness of HPV vaccination and its acceptance is poor in developing nations like India. India has a very high burden of oral cancer, and, unfortunately, the morbidity and mortality rates are also high as the cancer is often detected at an advanced stage. In this review, we explore the prevalence of HPV-associated head and neck squamous cell carcinoma among the Indian population and the awareness of HPV vaccination among Indian youth. Since the prognosis for HPV-associated head and neck squamous cell carcinoma is good, early diagnosis of the cancer is crucial in improving the outcome of the treatment modalities. Efforts are needed to create and increase awareness of HPV vaccination. Routine screening for HPV infection in oral mucosa can prevent the silent epidemic from taking the lives of many young people.

Abstract
Background Few studies explored Indonesian understanding of cervical cancer (CC) and the human papillomavirus (HPV) vaccination. We aimed to investigate the association between knowledge, attitudes, and practices (KAP) and socio-demographical influences related to HPV, CC, and vaccination among Indonesian urban citizens. Methods We conducted an online survey during March 2020-August 2021 using the Snowball sampling technique. The socio-demographic characteristic and KAP responses were collected via Google Forms from 400 respondents in Jakarta. The knowledge and attitudes were divided into HPV and CC (aspect 1) and HPV vaccination (aspect 2). Correlation between KAP scores was performed using Spearman’s test, and multiple logistic regression analyses were conducted to determine KAP predictors. Results Indonesian urban citizens in Jakarta were found to have poor knowledge in individual aspects of the inquiry but moderate knowledge overall, good attitude in inquiry both in each aspect and overall, and unsatisfying practices. Overall, in the general population, men, and women respectively: 50.8%, 32.4%, and 53.6% had good knowledge; 82.0%, 75.2%, and 84.4% expressed positive attitude; and 30.3%, 15.2%, and 35.6% applied favorable practice regarding questions inquired. Knowledge was weakly correlated towards attitude (ρ = 0.385) but moderately correlated with practice (ρ = 0.485); attitude was moderately correlated with practice (ρ = 0.577), all results: p<0.001. Significant odds ratio (OR) for predictors to good knowledge were female sex (OR = 2.99), higher education (OR = 2.91), and higher mother’s education (OR = 2.15). Factors related to positive attitudes were higher mother’s education (OR = 4.13), younger age (OR = 1.86), and better results in the knowledge inquiries (OR = 2.96). Factors that suggested better practices were female sex (OR = 2.33), being employed (OR = 1.68), excellent knowledge scores (OR = 4.56), and positive attitudes expressions (OR = 8.05). Having done one vaccination dose and intention to receive vaccines were significantly influenced by good KAP. Conclusions KAP had inter-association to successful CC and HPV prevention programs, and socio-demographical characteristics are critical to influencing better KAP.

Abstract
Cervical cancer is preventable yet one of the most prevalent cancers among women around the globe. Though regular screening has resulted in the decline in incidence, the disease claims a high number of lives every year, especially in the developing countries. Owing to rather aggressive and non-specific nature of the conventional chemotherapeutics, there is a growing need for newer treatment modalities. The advent of nanotechnology has assisted in this through the use of nanocarriers for targeted drug delivery. A number of nanocarriers are continuously being developed and studied for their application in drug delivery. The present review summarises the different drug delivery approaches and nanocarriers that can be useful, their advantages and limitation.

Abstract
BACKGROUND Cervical cancer, caused by human papillomavirus infection, is the source of significant personal and societal burden, and robs more than one hundred thousand Indian women and their families of the chances of a healthy and productive life each year. As outlined by the World Health Organization, the three-pronged approach of screening, vaccination, and reduction in mortality by early treatment presents the possibility of the elimination of cervical cancer as a public health problem in the next decade.1 Unfortunately, these approaches are all associated with significant barriers in India. OBJECTIVES Given that the main mandate of palliative care practitioners to prevent and relieve suffering, here we make the case for these practitioners to offer education around vaccination and screening to female relatives of women encountered with cervical cancer. CONCLUSION Offering prevention strategies for human papillomavirus aligns with the idea of preventing suffering and is within the scope of palliative care clinicians.

Abstract
PURPOSE Due to a wide range of Human Papillomavirus (HPV) types associated with genital cancers; HPV genotyping remains important for the introduction of an appropriate vaccine, disease diagnosis, follow-up and epidemiological surveys. Currently, available molecular genotyping assays are not only expensive but also requires dedicated and expensive equipment which is not feasible in the majority of low-and-middle-socioeconomic countries. The purpose of the study was to develop and evaluated a cost-effective nested-multiplex polymerase chain reaction (NM-PCR) assay for HPV genotyping. METHODS HPV-DNA containing plasmids and cervical scrapings from histologically confirmed cervical cancer cases were used to evaluate the NM-PCR. In the first round PCR, a set of consensus primers were used to amplify 38 mucosal HPV types. HPV Type-specific primers were used in the second-round polymerase chain reaction (PCR) to amplify 15 HPV types in three multiplex cocktails. The assay sensitivity was determined with the control panel containing one to 1010genome equivalents (GE). DNA sequencing was done to confirm the PCR results. RESULTS The assay was able to amplify all HPV types and detected as few as 50GE per reaction. A total of 23 endo-cervical samples obtained from healthy, HPV negative subjects and 52 histologically confirmed cervical scrapings were processed for HPV genotyping by NM-PCR. HPV DNA was detected in all histologically confirmed samples. DNA sequencing results showed complete concordance with PCR results. CONCLUSIONS The designed nested PCR based assay had good concordance with clinical histology and sequencing results and appears to be a promising tool for HPV genotyping especially in resource-constrained settings.

Abstract
Cervical cancer is the second most common cause of cancer deaths in women worldwide and remains the main reason of mortality among women of reproductive age in developing countries. Nitric oxide is involved in several physiological functions inclusive of inflammatory and immune responses. However, the function of NO in tumor biology is debatable. The inducible NOS (iNOS/NOS2) isoform is the one responsible to maintain the levels of NO, and it exhibits pleotropic effects in various cancers with concentration-dependent pro- and anti-tumor effects. iNOS triggers angiogenesis and endothelial cell migration in tumors by regulating the levels of vascular endothelial growth factor (VEGF). In drug discovery, drug repurposing involves investigations of approved drug candidates to treat various other diseases. In this study, we used anti-cancer drugs and small molecules to target iNOS and identify a potential selective iNOS inhibitor. The structures of ligands were geometrically optimized and energy minimized using Hyperchem software. Molecular docking was performed using Molegro virtual docker, and ligands were selected based on MolDock score, Rerank score, and H-bonding energy. In the study shown, venetoclax compound demonstrated excellent binding affinity to iNOS protein. This compound exhibited the lowest MolDock score and Rerank score with better H-bonding energy to iNOS. The binding efficacy of venetoclax was analyzed by performing molecular docking and molecular dynamic simulations. Multiple parameters were used to analyze the simulation trajectory, like root mean square deviation (RMSD), radius of gyration (Rg), and hydrogen bond interactions. Based on the results, venetoclax emerges to be a promising potential iNOS inhibitor to curtail cervical cancer progression.

COVID-19 Vaccine Hesitancy and Resistance in India Explored through a Population-Based Longitudinal Survey. Vaccines (Basel) 2021; 9:vaccines9101064. [PMID: 34696172 PMCID: PMC8537475 DOI: 10.3390/vaccines9101064] [Citation(s) in RCA: 77] [Impact Index Per Article: 25.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 09/14/2021] [Accepted: 09/17/2021] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND The World Health Organization has recommended that individual governments identify vaccine hesitancy areas. It is proposed that the governments, with the aid of local organizations, educate and implement social insights on the vaccination so that high population levels are covered with this safe immune program. METHODS A longitudinal online survey covered 3000 adults from India. We examined the demography, behavioral (socio-economic) attitude, vaccine hesitancy, vaccine resistance for the COVID-19 vaccine. The specific reasons for the COVID-19 vaccine decline were also evaluated. RESULTS Our survey revealed 59% definite response, 29% low-level response, and 7% high-level response for vaccine hesitancy, while 6% had resistant views on the COVID-19 vaccine. Individuals who had higher income levels, lived in a society, maintained social distancing, had downloaded the COVID-19 update app, showed a positive attitude towards their government, and more confidence in their healthcare system were more inclined towards the vaccination. On the contrary, individuals who had overstated the risks of COVID-19 and had a religious and populistic attitude towards vaccination were more hesitant/resistant to vaccination. The respondents who declined vaccine administration were further evaluated for their specific reason for their response. The most common reasons for declining the COVID-19 vaccine were post-vaccine scare of adverse health effects and accepting the information spread by social media. CONCLUSIONS The results in our study show that by identifying population "hot spots" that have negative or unclear information on the COVID-19 vaccination, these "hot spots" can be addressed by involving friendly organizations that can clear their strong disbeliefs and increase the percentage of vaccine-definite people within the population. The role of government-induced COVID-19 vaccine policy measures can always be beneficial to cause this shift from disbelief to confidence within the population.

Abstract
Human papillomavirus (HPV) remains the major cause of cervical cancer, globally. High risk HPV (Hr-HPV) 16 and 18 together account for more than 70% of cervical cancer cases, whereas the hr-HPV-18 is the second most prevalent hr-HPV type, causing about 5.2% of all cancers worldwide. Considering the high prevalence and mortality rate, cervical cancer remains a noteworthy health problem among women. As of now, no registered immunotherapies are available after the HPV infection. Thus, developing an immunotherapeutic candidate against hr-HPV would be of major clinical benefit. Nowadays, the T-and B-cell peptide based targeted vaccines have been considered as the best candidate for vaccine development against viral infections. In this study, both prophylactic and therapeutic vaccine candidates against hr-HPV-18 were predicted. To achieve this, the prediction of T-and B-cell epitopes of major histocompatibility complex (MHC) were accomplished, that can be used for HPV immunotherapy. For MHC-I, a maximum number (20) of potent peptides were found, against HLA-B*51:01 (L1 = 9, L2 = 6, E2 = 4, and E4 = 1) having percentile value < 1 and, immunogenicity scores higher than 0.5, followed by HLA-A*11:01 (L1 = 8, E2 = 7 L2 = 2, and E6 = 1, E7 = 1); 19 epitopes. For MHC-II, the highest number of peptides found, against the HLA-DRB1*04:01 (L2 = 10, E5 = 7, and E4 = 4), HLA-DRB1*04:05 (E5 = 7, E2 = 5, E4 = 5, and L1 = 4) HLA-DPA1*01:03/DPB1*04:01 (E7 = 7, E6 = 5, L2 = 5, and E2 = 2), HLA-DRB5*01:01(E6 = 6, L1 = 6, and L2 = 6); peptides 21, 21, 19 and 18 respectively. For B-cell, total 94, 16 amino acid long B-cell epitopes were predicted. In conclusion, these predicted epitopes can be valuable candidates for in vitro or in vivo therapeutic vaccine studies against hr-HPV-18 associated cancer.

Abstract
Lack of awareness of screening methods, risk factors, and symptoms may lead to late diagnosis and poor prognosis of cervical cancer. The plan of this study was to assess the level of awareness about cervical cancer and HPV vaccine among females of rural and urban areas of Haryana, India. This cross-sectional study was performed using a comprehensive self-designed questionnaire on 1500 women of urban (700) and rural (800) background aged 18-65 years, evaluating their knowledge for cervical cancer and screening, HPV infection and its preventive measure, and symptoms and risk factors. Data obtained was analyzed and interpreted by using simple percentages and bar charts. Most of the participants were aged between 21 and 30 years and had college level education. Majority of the women from rural areas had poor knowledge about cervical cancer (55%) and its screening (75%), HPV infection (87.5%), and HPV vaccine (95%) compared with urban areas. Knowledge about symptoms and risk factors was very low in both rural and urban areas. Whatever little knowledge the women had about cervical cancer was from college education, friends, neighbors, relatives, and medical practitioner or doctors. The survey pointed to the critical need to educate women about cervical cancer and its early diagnosis, related risk factors, symptoms, and preventive measures which can be achieved by launching extensive awareness programs for educating females about cervical cancer in India.

Abstract
Background: Cervical cancer (CC) is a foremost reason of global cancer death in women, and a good portion remains with the developing countries. This study was conducted to assess the knowledge, attitude, and practice regarding Pap smear, CC, and Human Papillomavirus (HPV) among the women attending a Mother and Child Health Clinic in Kuantan, Malaysia. Materials and Methods: A total of 120 respondents involved in this cross-sectional study. The convenience sampling was to select the respondents. The data were collected from in 2013. Results: The mean age 32.19 years. Up to 54.2% of respondents never had Pap smear in the past 5 years, while over 67.5% of respondents never had HPV vaccination. There was a significant correlation between knowledge with attitude (P < 0.001) and attitude with practice (P < 0.001) regarding Pap smear, CC, and HPV. However, knowledge and practice regarding Pap smear, CC, and HPV was not significantly correlated (P = 0.525). There was no significant correlation between mean age and knowledge (P = 0.455) while there was a significant correlation between mean age with attitude (P = 0.011) and practice (P < 0.001) regarding Pap smear, CC, and HPV. It was also shown that there were differences between races in term of knowledge and attitude (P < 0.05). However, there was no significant difference in term of practice regarding Pap smear, CC, and HPV (P > 0.05) between races. Conclusions: Important barriers to Pap smear screening among women are highlighted through this study. The health institution involved needs to come up with better strategies to deal with these barriers to improve the awareness of women regarding Pap smear, CC, and HPV.

Abstract
BACKGROUND Cervical cancer is an AIDS-defining illness, and HIV-positive women are at high risk. The present study aimed to determine the magnitude of the problem, compare the performance of screening tests and assess factors affecting participation. METHODS HIV-positive women aged 30-59 years attend the anti-retroviral therapy (ART) clinics were screened by conventional Pap, HPV testing (Hybrid Capture 2) and visual inspection with acetic acid (VIA). A cohort of HIV-negative women from the community matched for age and parity were screened similarly. Screen-positive women underwent colposcopy and biopsy. Factors affecting participation were assessed. RESULTS Pap, VIA and HPV were positive in 48 (23.8%), 65 (32.2%) and 76 (37.6%) subjects, respectively, among HIV-positive women, and in 12 (5.9%), 10 (4.9%) and 12 (5.9%) subjects, respectively, among HIV-negative women. CIN2 + was present in 12 (6.4%) HIV-positive women and in 1(0.5%) HIV-negative woman (p = < 0.004). Sensitivity of HPV, Pap and VIA for detection of CIN2 + lesions was 91.7%, 75.0% and 75.0%, respectively; specificity was 68.4%, 83.9% and 72.5%, respectively. Lack of availability of screening facilities in the ART clinic and long waiting times were a strong deterrent to participation among HIV-positive women. CONCLUSIONS There was higher prevalence of HPV infection and CIN2 + lesions in HIV-positive women. VIA showed equivalent sensitivity to Pap and could be a good substitute in low resource settings. Setting up cervical screening services in ART clinics and sensitising physicians can improve outcomes among these women.

Abstract
In India, cervical cancer screening is conducted at various levels; however, after screening, the adherence to the cancer care continuum is barely understood. This study evaluated a community-based cancer screening program conducted in a rural setting (Tirunelveli and Tuticorin districts) in South India and reviewed the completion of care continuum. In this longitudinal descriptive study involving secondary data collection, data from the case records of 2192 women who were consecutively screened between March 2015 and May 2016 were included. All women underwent conventional cytology-based screening (Pap smear) and Visual Inspection with Acetic Acid (VIA). Those for whom either test was positive were referred for histopathological confirmation. Patients with confirmed precancerous conditions and unsatisfactory Pap smears were referred for further management. In total, 2192 women were screened [age range, 17-69 years; mean (standard deviation), 39.2 (8.5)]. Common symptom and sign were white discharge per vaginum (34.9%) and cervical erosion (34.4%), respectively. The VIA was positive for 24% (523/2178; 14 women did not cooperate for VIA) and 113 (5.1%) had epithelial cell abnormality in the Pap smear test. Per histopathology findings, one woman had non-keratinizing squamous cell carcinoma. Seven, three, and four had cervical intraepithelial neoplasia I, II and III, respectively. Of 2192, 807 were eligible for referral (597 had positive results on either Pap or VIA). Among the 807 women referred, only 74 (9.2%) women visited the referral center. The follow-up rate was very poor accounting to fragmentation of care continuum. The success of the screening program depends on the completion of the care continuum.

Abstract
Aldo-keto reductase 1C1 (AKR1C1) is a hydroxysteroid dehydrogenase, known to inactivate the biologically active progesterone into its corresponding 20 α-hydroxyprogesterone. Increased expression of the AKR1C1 gene in oncogenesis is linked with resistance to various anticancer agents and hence it is considered as an emerging drug target for the design and developing the novel anticancer drugs. We have performed QSAR pharmacophore modeling for AKR1C1 inhibitors followed by a virtual screening of ~ 59,000 compounds present at the Maybridge database. The screened compounds were refined using drug-like filters of Lipinski rule, ADMET plot, molecular docking and scoring and subsequently top 20 hits were selected. Selected compounds were subjected to the in vitro for AKR1C1 inhibition assay and best seven compounds bearing excellent binding affinity to the AKR1C1 were finally selected. The identified compounds may be exploited in hit-to-lead development and may also prove as an interventional strategy in preventing a pre-term birth due to declining levels of progesterone.

Abstract
Background: Initial introduction of HPV vaccination from 2006 to 2008 was largely confined to high-income countries (HIC), such as Australia, the United States, and Europe, where cervical cancer incidence is lowest. Much of the post-introduction literature has come from HICs, with a focus on coverage levels achieved, provider acceptability and early impact of vaccination on disease endpoints. However, there are a few literature evaluating the mechanics of delivery, feasibility of the health system and acceptability from low and middle income countries (LMICs). The primary objective was to evaluate the feasibility, acceptability and safety of two dose HPV vaccination in adolescent girls between 9-14 years. Methods: After an orientation camp followed by filling up of prevaccine questionnaires by parents on HPV related diseases and its vaccines and informed consent, girls between9-14years were vaccinated. They were asked to report any side effects in the next 24 hours after each dose. Parents were contacted on Day 7 and Day 30 to enquire about any side effects . Total 3 visits were required i.e two for the vaccination and one visit at 7th month post completion of second dose. To estimate the acceptability, successful completion of two doses by at least 80% of the girls were measured. For measurement of acceptability, either of the parents were recalled along with their daughter at 7th month and were asked to fill up a pre-set questionnaire. Results: After institutional ethical clearance, 555 girls were recruited in the study from rural parts of West Bengal, India between July, 2017 to November, 2017. Out of which, 544 girls (98%) received their 2nd dose between January, 2018 and May, 2018 without any serious adverse effects. No serious adverse effect was reported on follow up till December, 2019. Conclusion: The introduction of HPV vaccination is feasible in large scale and the vaccine is well accepted and safe.

Abstract
Background Despite the fact that cervical cancer is preventable and curable in the early stages, it still remains to be a major public health problem in India. This study was conducted to assess the knowledge and awareness regarding the Human Papilloma Virus (HPV) vaccination among health care professionals working in a tertiary care hospital in urban India. Methods To this aim, we conducted a cross-sectional study among 318 health care professionals working in tertiary hospitals across Chennai, Tamil Nadu, India. Our research group designed a structured questionnaire with 31 items to assess the knowledge and attitudes on cervical cancer, its prevention, and HPV vaccination. Results Among the 318 respondents, 90.6% were aware of cervical cancer, 83.3% were aware that PAP (Papanicolaou) smear test detects cervical cancer, and 86.2% of the respondents knew that HPV causes cervical cancer. 29.2% of the eligible respondents underwent the screening against cervical cancer, and 19.8% of the study participants were vaccinated for HPV. Only 34.9% know that the HPV vaccine could be given to boys. The most common reason for not being vaccinated against HPV was the lack of awareness. In our study, 77.2% of the respondents were willing to be vaccinated and recommend HPV vaccination to their family members. Conclusion From this study, it was evident that there is a lack of awareness about HPV vaccination and its importance in preventing cervical cancer among healthcare professionals. Our finding clearly establishes the need to devise intervention programs to promote vaccination against HPV and periodical screening for cervical cancer among healthcare professionals.

Abstract
BACKGROUND India has almost 225 million adolescent girls and they seem to be at a disadvantage, both economically and by their lack of knowledge on human papilloma virus (HPV) vaccine, when compared to adolescent girls of other Asian countries. AIM To assess the prevalence of HPV vaccination and to identify the impact of education in improving the knowledge and perception about the HPV infection and vaccination among the parents of adolescent girls. METHODOLOGY The prospective interventional study was conducted in four schools within a South Indian City, Mysuru. The informed consent form and the questionnaire were sent home with the identified adolescent girls during the pre-interventional phase. Educational sessions were conducted for the students in their school and an education leaflet was distributed to their parents. Three weeks later, questionnaires were re-administered to the parents via the enrolled girls and their responses were collected. RESULTS The prevalence of HPV vaccination in the study population was 4.4%. There was a statistically significant improvement in knowledge in the post-interventional phase of the study (p = 0.001), but could not identify a significant change in their perception (p = 0.479). Parents belonging to the socioeconomic class of upper middle and upper lower showed better improvement at the end of the study, with a percentage improvement of 58.93% and 48.44%, respectively. CONCLUSION The study proved that the healt care professional can target school children to communicate effectively to their parents on the importance of HPV vaccine as the study clearly observed a positive behavioral change among the study population.

Abstract
BACKGROUND Atypical glandular cells (AGC) as a diagnostic category in cervicovaginal cytology remains as a challenge to cytopathologists. AIMS The aim of the present study is to identify the cytological features helpful in categorizing AGC as reactive or neoplastic upon correlation with histology. MATERIALS AND METHODS The study was a retrospective review of cervical smears, with histopathological follow up, reported as glandular lesions for a period of 9 years. The architectural and nuclear features studied were adapted from The Bethesda System (TBS) to stratify the lesions as AGC, AGC-FN (atypical glandular cells favour neoplasia) and adenocarcinoma. The cytological categories were correlated with histology. RESULTS A total of 89 cases of which 67 (AGC NOS = 34, AGC FN = 19, adenocarcinoma = 14) with histology were reviewed. Neoplastic lesions were encountered in 14 cases (34.6%). Of the cases diagnosed as AGC-NOS, AGC-FN and adenocarcinoma, 26.5%, 68.4% and 100% respectively were neoplastic on histopathology. Squamous lesions accounted for 14.9% of all the glandular lesions. Rosette or acinar formation and loss of polarity frequently observed in neoplastic lesions as compared to reactive changes (p = 0.0004, p = 0.001). Of the nuclear features, nuclear hyperchromasia or coarse clumping of chromatin along with nuclear membrane irregularity and nuclear pleomorphism was frequently associated with neoplastic lesions as compared to reactive conditions (p = 0.007, p = 0.001, p = 0.0002). CONCLUSION A diagnosis of AGC at cytology harbors significant number of malignant lesions when confirmed on biopsy. Architectural features complemented with nuclear characteristics helps in differentiating between reactive and neoplastic conditions. Hence stratifying glandular lesions at cytology according to TBS helps in the management.

Abstract
The aim of the study is to investigate the expression of angiogenesis (VEGF and PDGF), angiogenesis inhibitor markers (angiostatin and endostatin), proliferation (Ki67), and apoptosis markers (p53 and p16) of cervical cancer in Indian population and to correlate them with the clinicopathological profile. It is a descriptive study of consecutive cases of cervical cancer from Saveetha Medical College and Hospital between January 2017 and December 2018. The expression of angiogenesis, angiogenesis inhibitor markers, Ki67, p53, and p16 in 60 cases of cervical sections were detected by the immunohistochemical method and analyzed with clinicopathological data. VEGF expression was positive in 16 cases (26.67%) and negative in 20 cases (33.33%). As of PDGF, 3 cases (3.33%) have shown positivity to PDGF and 33 cases have shown negativity. Angiostatin and endostatin expression was reported to be positive in 10 (16.67%) and 21 (35%) cases, respectively. Most of the cases 57 (95%) have shown both p16 and Ki67 positivity. Although p53 expression was positive in 48 cases (80%), the remaining 12 cases (20%) were p53-negative. The PDGF expression was significantly correlated to the stage of tumors. No statistically significant association was observed between angiogenesis inhibitor markers and clinicopathological parameters. A significant positive correlation was noticed between the Ki67 expression and stage of tumors.

Abstract
SIGNIFICANCE Mueller matrix polarimetry can provide useful information about the function and structure of the extracellular matrix. A portable and low-cost system could facilitate the clinical assessment of cervical anomalies in low-resource settings. AIM We introduce a low-cost snapshot Mueller matrix polarimeter that does not require external power, has no moving parts, and can acquire a full Mueller matrix in ∼1 s, to conduct a feasibility study for cervical imaging in the low-resource setting. APPROACH A snapshot system based on two sets of Savart plates, a ring illuminator with polarizing elements (generating four polarization states), and one camera is introduced. Stokes vectors are formulated to recover the polarization properties of the sample. Then, using Mueller matrix decomposition, the depolarization and retardance information is extracted. RESULTS We report the results on 16 healthy individuals (out of 22 patients imaged), whose Pap smear showed no malignant findings from mobile clinics in rural region of Mysore, India. The depolarization and retardance information was in agreement with previous reports. CONCLUSIONS We introduce an imaging system and conducted a feasibility study on healthy individuals. This work could futurely translate into diagnostic applications to provide a quantitative platform in the clinical environment (e.g., cervical cancer screening).

Abstract
Background Breast cancer and cervical cancer, the most common forms of cancer in women worldwide, are on a fast and steady rise, accounting for more deaths in women than any other cancer in the developing world. Cancer screening tests are an important tool to combat cancer-related morbidity and mortality. World Health Organization aims to accelerate action to achieve Goal 3.4 of the Sustainable Development Goals (SDG 3.4) in order to reduce premature mortality from non-communicable disease, including cancer by one-third by 2030. This study aims to examine the geospatial variation of cervical and breast screening across districts and to identify factors that contribute to the utilization of screening among women in India. Methods Until recently, there was no evidence pertaining to screening for cervical and breast cancers at the national level. Information on examination of the breast and cervix from over 699,000 women aged 15–49 years was collected for the first time in the fourth round of National Family Health Survey, 2015–16 (NFHS-4). For the present study, the data were aggregated for all 640 districts in India. Moran’s Index was calculated to check for spatial autocorrelation. Univariate Local Indicators of Spatial Association (LISA) maps were plotted to look for spatial dependence associated with the uptake of screening practices. The spatial error model was employed to check for spatial magnitude and direction. Results The common factors associated with uptake of both cervical and breast screening at the district level were; women belonging to a general caste, residing in rural areas, being currently married, and being well-off economically. Being insured was positively associated with the uptake of cervical screening only. This study provides spatial inference by showing geographical variations in screening of cervix and breast across districts of India. Conclusions By showing geographical disparities in screening practices across districts of India, this study highlights the importance of ensuring a region-specific and organ-specific approach towards control and prevention of cancer. The identified factors responsible for the uptake of screening could be a guiding force to decide how and where tailored interventions may be best targeted.

Abstract
BACKGROUND As per WHO, Cervical cancer (CaCx) is a global issue, being the fourth common cancer in women with incidence rate of 13.1 per 1 lakh women globally and accounting for 311000 deaths in the year 2018 itself globally. The molecular pathogenesis in Human papillomavirus (HPV) infected cases is inconclusive. The detection of molecular factors leading to progression of CaCx can be important in the diagnosis and management of the disease. p53 a known tumor suppressor gene having a regulative role in cell cycle has been highlighted as key factor in the prevention of cancer but its significance in CaCx cases has been variably documented. The present study therefore targeted to evaluate the significance of p53 profile in CaCx cases in ethnically distinct northeast Indian population. METHODS Blood and Tissue samples (N = 85) of cervical cancer patients were collected and screening for HPV was performed using PCR. Thereafter the differential mRNA expression(qPCR), Immunohistochemistry, Mutation (PCR direct sequencing method) of p53 was studied. Further p53 epigenetic profiling was done by Methylation specific PCR (MS-PCR) and western blotting by using p53 acetylation specific antibodies. RESULTS Our findings revealed that the downregulation of p53 was associated with the progression of disease and the variation in downregulation based on p53 polymorphism was observed. Further hypermethylation and deacetylation of p53 was also found to be associated with the pathogenesis of CaCx. The downregulated expression and hypermethylation of p53 in lower grade of CaCx, together established its association with the progression of CaCx from lower to severe grade. CONCLUSION Therefore, in CaCx patients of northeast Indian population, malfunctioning of p53 is found to have significant role in cervical cancer progression.

Abstract
Vaccines have contributed substantially to decreasing the morbidity and mortality rates of many infectious diseases worldwide. Despite this achievement, an increasing number of parents have adopted hesitant behaviours towards vaccines, delaying or even refusing their administration to children. This has implications not only on individuals but also society in the form of outbreaks for e.g. measles, chicken pox, hepatitis A, etc. A review of the literature was conducted to identify the determinants of vaccine hesitancy (VH) as well as vaccine confidence and link them to challenges and opportunities associated with vaccination in India, safety concerns, doubts about the need for vaccines against uncommon diseases and suspicions towards new vaccines were identified as major vaccine-specific factors of VH. Lack of awareness and limited access to vaccination sites were often reported by hesitant parents. Lastly, socio-economic level, educational level and cultural specificities were contextual factors of VH in India. Controversies and rumours around some vaccines (e.g., human papillomavirus) have profoundly impacted the perception of the risks and benefits of vaccination. Challenges posed by traditions and cultural behaviours, geographical specificities, socio-demographic disparities, the healthcare system and vaccine-specific features are highlighted, and opportunities to improve confidence are identified. To overcome VH and promote vaccination, emphasis should be on improving communication, educating the new generation and creating awareness among the society. Tailoring immunisation programmes as per the needs of specific geographical areas or communities is also important to improve vaccine confidence. Fig. 1 Plain language summary.

Abstract
Background: Despite immense advancements in treatment modalities, cancer remains a dreadful disease until the present. The major influencing factors behind the increased mortality rate of cancer are increased drug resistance and severe adverse effects caused by conventional cancer therapies. To overcome these limitations, the current medical field is focusing more on natural phyto-derived molecules to mitigate cancer. Mangosteen is a phytotherapeutic with potent anti-inflammatory and antioxidant properties. In the present study, we investigated the anticancer potential of the crude ethanolic extract of mangosteen against two dreadful forms of cancers, namely, oral cancer and cervical cancer, in vitro. Methodology: The pericarp of Garcinia mangostana or mangosteen was removed, air-dried, ground to fine powder, and macerated with ethanol. The extract obtained was then filtered and extracted with water for 48 h. The aqueous fraction thus obtained was then concentrated with a rotary evaporator at 40°C and dried with a freeze dryer. The anticancer efficacy of these extracts was investigated in human tongue squamous cell carcinoma (H357) cells and cervical cancer cells (HeLa) using the MTT assay, TUNEL assay, western blotting, and flow cytometry techniques. Results: The crude mangosteen pericarp extract (MPE) significantly inhibited the growth of H357 and HeLa cells in a dose-dependent manner. Moreover, mangosteen induced early apoptosis in these cells after 48 h of incubation. Mangosteen also upregulated the expression of pro-apoptotic proteins, including caspases and Bax, and downregulated the expression of anti-apoptotic protein Bcl-2. Conclusion: The MPE exerted significant cytotoxicity against the H357 and HeLa cells in a dose-dependent manner and promoted their apoptosis. Hence, this natural phytoextract can be considered a potent anticancer agent for treating oral cancer and cervical cancer.

Abstract
BACKGROUND There is, till date no population-based data regarding cancer patterns in North- Eastern India, dictating the need to understand the epidemiology of cancer in this population for its effective management. METHODS This is the first report of the Population Based Cancer Registry (PBCR) in Tripura (2010-2014). The protocol involves active collection of data on all cancer cases from Tripura through staff visit in more than 150 sources of incident and mortality registration, government and private hospitals, municipal corporation, etc. and scrutiny, corroboration with existing records. Data was analyzed statistically to understand cancer trends in terms of incidence and mortality across different sites, age groups affected and gender. RESULTS A total of 10,251 cases were registered during the period, with overall age-adjusted incidence rates of 75.7 and 54.9 per 100,000 males and females respectively. Crude Incidence Rate (CR) and Age- Adjusted Rate (AAR) was among the lowest reported in India, probably due to associated socio-economic factors. The most prevalent cancers were lung (18.1%), esophageal (8.3%) for men and cervix uteri (17.6%), breast (13.8%) for females. Gall bladder cancer in females was one of the highest in the country. Rate of cancer mortality in the population was quite high and significantly increased with time, probably accounting for dearth in early detection and feasible treatment alternatives. CONCLUSION The data suggests that high cancer incidence and mortality are prevalent in the population of Tripura, dictating the need of active tobacco control measures, early detection and awareness drives for effective cancer control.

Abstract
Abstract
Background
There are many biomarkers associated with breast cancer. Higher expression of PIK3CA (Phosphoinositide 3-kinase Cα), in its upregulated form, is associated with Hr+ and Her2− breast cancer; therefore, many drugs were synthesized against this protein to treat breast cancer patients. FDA recently approved that the drug alpelisib also inhibits PI3KCα (PDB ID-5DXT) in BC patients with Hr+ and Her2−. In present study, we have exploited fourteen coumarin-carbonodithioate derivatives and alpelisib against this protein along with eighteen others which are responsible for causing BC through computational analysis. We have used Schrödinger Maestro 11.2 version for our in silico docking study, and to calculate relative binding energies of ligands, we used prime MM-GBSA module.
Result
Docking study revealed that among all fourteen compounds, 2f, 2a, 2d, and 2e showed the highest G score than the alpelisib and coumarin against PI3KCα with − 9.3, − 9.0, − 9.0 and − 9.1 kcal/mol respectively, along with individual G score of alpelisib (− 8.9) and coumarin (− 7.9). Prime MM-GBSA analysis gave the relative binding energies of alpelisib, 2f, and 2e with − 19.94864535, − 18.63076296 and − 13.07341286 kcal/mol sequentially.
Conclusion
This study provides an insight into the coumarin-carbonodithioate derivatives that could act as inhibitors of PI3KCα like alpelisib. Further prime MM-GBSA study revealed ligand binding energies and ligands strain energies.

Aberrant promoter methylation of NOTCH1 and NOTCH3 and its association with cervical cancer risk factors in North Indian population. Am J Transl Res 2020; 12:2814-2826.

Abstract
Cervical cancer is the fourth most common type of cancer in women worldwide, and associated mortality is highest in developing countries like India. Limited studies are available on the role of NOTCH signaling pathway and promoter methylation in cervical cancer. In the current study, we investigated the promoter methylation status of NOTCH receptor genes (mainly NOTCH1, NOTCH2, and NOTCH3) and its correlation with gene expression, clinicopathological factors, and prognosis of cervical cancer. A total cohort of 110 cervical cancer patients of North Indian origin was enrolled in the study. From 28 of these patients, biopsies from adjacent non-cancerous tissue were available to serve as healthy controls. Promoter methylation status and mRNA expression level of NOTCH1, NOTCH2, and NOTCH3 were determined by methylation-specific PCR (MSP) and real-time quantitative (RT-qPCR), respectively. NOTCH1 and NOTCH3 promoters were methylated in 92% (P<0.0001), and 61% (P<0.001) of the cervical cancer biopsies. We did not observe a statistically significant change in the promoter methylation level of NOTCH2. Further, NOTCH1, NOTCH2, and NOTCH3 were down-regulated in cervical cancer biopsies, but the differential expression of only NOTCH1 was found statistically significant. The promoter methylation levels of all three genes also showed a statistically significant association with clinicopathological factors and HPV infection (Type 16 and 18) but we did not observe a statistically significant relationship between their methylation status and gene expression. Overall our results provide evidence of the altered methylation and expression status of NOTCH1 and NOTCH3 receptor genes in cervical cancer. This study of NOTCH gene promoter methylation may provide a new perspective for early screening and diagnosis of cervical cancer.
