Abstract
INTRODUCTION MicroRNAs (miRNAs) are well-established post-translational non-coding RNAs that play crucial roles in mRNA degradation and repression. Glucose transporter 1 (GLUT1) showed correlation along with various miRNA, specifically miRNA10a expression in lung cancers. The role of miRNA10a along with glucose upregulation leading to cancer proliferation in oral squamous cell carcinoma (OSCC) is unknown. This study aimed to investigate the expression levels of miRNA10a and GLUT1 in OSCC patients with diabetes. MATERIALS AND METHODS miRNA10a and GLUT1 expression were estimated in OSCC, precancerous, and healthy tissues using quantitative reverse transcriptase polymerase chain reaction (RT-PCR). miRNA10a and GLUT1 expression levels were recorded as fold change. Further, a one-way analysis of variance (ANOVA) test was performed to find whether there is any difference in miRNA10a and GLUT1 expression between OSCC, precancerous, and healthy tissues. RESULTS The RT-PCR findings revealed an increased expression of miRNA10a and GLUT1 in OSCC compared to precancerous and healthy tissue. There is a positive correlation between miRNA10a and GLUT1 expression levels in both potentially malignant and control tissues, with a marked increase in cancerous tissue. This study demonstrated the significance of upregulated miRNA10a expression, indicating a direct correlation with OSCC proliferation via GLUT1 overexpression. Specifically, miRNA10a exhibited a fold change of 1.2±0.072 in potentially malignant tissue and 1.4±0.05 in cancer tissue, while GLUT1 exhibited a fold change of 1.25±0.092 in potentially malignant tissue and 0.092±0.08 in cancer tissue, respectively. CONCLUSION This research highlights the role of miRNA10a in cancer progression by facilitating proliferation through the regulation of GLUT1 in cancerous tissues, particularly in hyperglycemic conditions. This mechanism further contributes to increased glucose transport in cancer patients, which may potentially impede tumor prognosis. These findings underscore the potential significance of targeting miRNA10a and GLUT1 as therapeutic interventions in cancer management.

Abstract
Background Tumor necrosis factor-alpha (TNF-α) has a pivotal role in the pathogenesis and prognosis of cancer as well as diabetes mellitus (DM). Many oral squamous cell carcinoma (OSCC) patients are reported to have associated comorbidities such as type 2 diabetes mellitus (T2DM). Furthermore, T2DM exaggerates inflammation due to a lack of insulin action. Therefore, OSCC patients with T2DM may progress to the advanced stage more rapidly resulting in reduced survival even after glycemic control creating a challenge to oncologists in managing these patients. Unfortunately, it is difficult to predict the course of disease in these patients just based on clinical and radiological parameters. Considering the impact of TNF alpha in both disease progression, it is an interesting biological marker to explore. Further, saliva being a noninvasive biological fluid can help measure the TNF-α levels, thereby predicating the prognosis of OSCC. Unfortunately, there is limited information about the salivary TNF-αnf levels in OSCC patients with DM. Aim The aim of this study was to compare the salivary TNF-α in OSCC patients with and without DM. Methods Saliva samples were obtained from healthy individuals, OSCC patients with DM, and OSCC patients without DM. The quantification of TNF-α levels was performed using the EliKine™ Human TNF-α ELISA Kit, an enzyme-linked immunosorbent assay. The data were reported as means and standard deviations. To assess variations in salivary TNF-α levels among these groups, the Kruskal- Wallis test was employed. Results The study included a total of 30 participants with 10 in each group. There were 18 males and 12 females with a mean age of 37.2± 4.7 years. The TNF-α levels between the control group (51+42±1.4 pg/ml), OSCC patients without DM (67.43 ±1.7 pg/ml), and OSCC patients with DM (268±8.5 pg/ml) were noted. The mean salivary TNF-α level was statistically higher in OSCC with DM compared to the control and OSCC without DM group. Conclusion The investigation compared the salivary TNF-α in OSCC patients with and without DM and has uncovered substantial differences in TNF-α concentrations within the examined cohorts, providing insights into the potential involvement of TNF-α in the context of OSCC, especially in patients with DM. Nevertheless, additional research is imperative to establish associations between TNF-α levels, the prognosis of OSCC, and the impact of DM.

Abstract
Introduction Citrus fruit peels contain Tangeretin, a natural chemical flavonoid that reinforces plant cell walls and serves as a defense mechanism. Apoptosis, growth inhibition, anti-oxidant, anti-diabetic, and anti-cancer activities are only a few of its many qualities. Tangeretin's principal function is to shield healthy cells or tissues from the harmful effects of chemotherapy. The purpose of this study was to investigate the apoptotic activity of Tangeretin's impact on KB (oral cancer cells) cell lines. Materials and method This study employed Tangeritin, in investigating its effects on oral cancer cells. Oral cancer cells were cultured in Dulbecco's modified Eagle's medium (DMEM), with 10% fetal bovine serum at 37°C in a 5% CO2 environment. Cell viability was assessed by seeding oral cancer cells in 96-well plates, exposing them to varying Tangeritin concentrations (50 µM, 100 µM, and 200 µM) with growth inhibition of KB cell viability in 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and morphological changes in cells were observed under an inverted light microscope at 10x magnification. The results were reported as mean ± standard error mean (SEM) using one-way analysis of variance through IBM SPSS Statistics for Windows, Version 23 (Released 2015; IBM Corp., Armonk, New York, United States). Result MTT assay showed a significant reduction in KB cell viability when treated with Tangeretin. With a significant decrease in mRNA levels of the anti-apoptotic genes Bcl-2 and Bcl-xL. At 50 µM, 100 µM, and 200 µM, the levels of Bcl-2 were 0.85 ± 0.09, 0.62 ± 0.05, and 0.67 ± 0.05, respectively. Similarly, the mRNA expression of Bcl-xL was 0.82 ± 0.07 for 50 µM, 0.7 ± 0.06 for 100 µM, and 0.77 ± 0.06for 200 µM. The mRNA expression levels of Bax were 1.1 ± 0.09 for 50 µM, 1.4 ± 0.12for 100 µM, and 1.3 ± 0.11 for 200 µM, respectively. Conclusion Tangeretin showed a promising apoptotic activity in KB cells suggesting its utility as an anti-cancer compound. It prevented the growth and proliferation of cancer cells by acting on pro-apoptotic and anti-apoptotic genes. However, this conclusion is mostly based on the in vitro study. Therefore in vivo animal studies were needed to confirm the findings.

Abstract
Aim The aim of the study is to analyse the knowledge about oral lesions, the symptoms of such lesions and their attitude towards the treatment of these problems faced by institutionalised geriatric individuals. Methods and Materials This questionnaire-based survey was conducted among 103 institutionalised elders residing at various institutions. The questionnaire consisted of questions that addressed the medical and dental issues faced by the institutionalised elders and assessed their knowledge and attitude towards dental health. All the received responses were tabulated and the results were represented graphically. Results The results of the study showed that 44.66% of the elders underwent medical check-up once yearly and 72.82% of them visited the dentist. Of all 103 elders, none of them used dentures in spite of being edentulous and only 29.13% had any knowledge about oral lesions while the rest had no knowledge of the oral lesion and considered these lesions to be normal changes with increasing age. Conclusions The findings of the present study demonstrate the need to improve access to oral healthcare and dental health education for the institutionalised elder population. In spite of the limitations of the study, we were able to record the obvious lack of dental hygiene practises, neglect and lack of motivation for proper dental care.
