    Epigenetic regulation of gene expression is critical to phenotypic maintenance and transition of human breast cancer cells. HOX antisense intergenic RNA (HOTAIR) is a long intergenic non-coding RNA that epigenetically represses gene expression via recruitment of enhancer of zeste homolog 2 (EZH2), a histone methyltransferase. Elevated expression of HOTAIR promotes progression of breast cancer. In the current study we examined the expression and function of HOTAIR in MCF-7-TNR cells, a derivative of the luminal-like breast cancer cell line MCF-7 that acquired resistance to TNF-α-induced cell death. The expression of HOTAIR, markers of the luminal-like and basal-like subtypes, and growth were compared between MCF-7 and MCF-7-TNR cells. These variables were further assessed upon inhibition of HOTAIR, EZH2, p38 MAPK, and SRC kinase in MCF-7-TNR cells. When compared with MCF-7 cells, MCF-7-TNR cells exhibited an increase in the expression of HOTAIR, which correlated with characteristics of a luminal-like to basal-like transition as evidenced by dysregulated gene expression and accelerated growth. MCF-7-TNR cells exhibited reduced suppressive histone H3 lysine27 trimethylation on the HOTAIR promoter. Inhibition of HOTAIR and EZH2 attenuated the luminal-like to basal-like transition in terms of gene expression and growth in MCF-7-TNR cells. Inhibition of p38 and SRC diminished HOTAIR expression and the basal-like phenotype in MCF-7-TNR cells. HOTAIR was robustly expressed in the native basal-like breast cancer cells and inhibition of HOTAIR reduced the basal-like gene expression and growth. Our findings suggest HOTAIR-mediated regulation of gene expression and growth associated with the basal-like phenotype of breast cancer cells

    Get PDF
    Introduction Lipoblastoma is a rare benign tumour arising from embryonic white fat been commonly noted in limbs and trunk, but tongue involvement is rare and has not yet been reported. Case Report A child with tongue lipoblastoma is reported, whose imaging reported an encapsulated, well-delineated, fat-containing tumour. Surgical excision was performed with no post-operative morbidities.  Discussion Lipoblastoma is an uncommon childhood tumour, which rarely affects the tongue. It presents as a progressive painless swelling, rarely causing any symptom. MRI is helpful to assess the precise location and extent of the lesion. Although the ratio of fat to myxocollagenous tissue in the tumour is variable, the diagnosis can be suggested in most cases based on the imaging characteristics. Recommended treatment is complete surgical excision and confirmation of diagnosis by histopathological examination

    Get PDF
    Background: In rural India, women\u27s empowerment is hindered by challenges such as limited access to education, economic opportunities, and healthcare services, compounded by entrenched gender inequalities. Addressing these issues requires comprehensive assessments of empowerment indicators to inform targeted interventions and policy initiatives aimed at promoting gender equity and sustainable development. The utilization of various national and state women welfare schemes varies based on awareness level and access, which are determined by socioeconomic factors. Therefore, this research aimed to assess the various dimensions of women empowerment, and various factors associated with it, and the utilization of government welfare schemes. Objectives: To measure the various dimensions of women empowerment (household autonomy, freedom of mobility, gender preference & domestic violence, etc.,) among women in the adopted villages of a private medical college. To find the various factors associated with the dimensions of women empowerment. To estimate the utilization of government women welfare schemes among women in the adopted villages. Methodology: A cross-sectional study involving 587 married women out of 3833 females were selected by stratified random sampling among each stratum (5 adopted villages). All married women < 60 years old in the village willing to participate were included in the study, excluding widows. The data was collected using a pretested standardized questionnaire adopted from the Demographic and Health Survey (DHS) containing socioeconomic demographic details, indicators of women empowerment, and utilization of women welfare programs. The data was collected by the personal interview method. Results: The mean age of the study population was 39±12 [CI: -4.155 to 0.173].  Among the 587 study participants, 74.1% of women have autonomy over making household decisions, 62.2% have freedom of mobility, 69.8% responded that it is adequate if their girl children are educated up to high school, 74.8% of women have a positive attitude against domestic violence. 34.2% of women were registered and utilized the Mahatma Gandhi National Rural Employment Guarantee Act (MGNREGA) scheme. Conclusion: This study showed that women empowerment is improving in rural areas over time. However, regular promotional and awareness campaigns are required to improve various dimensions of women empowerment and their quality of life

    Berberis aristata DC. (Fam: Berberidaceae) commonly known as Daruharidra, Indian Barberry or tree turmeric. Leaves of this plant are traditionally used in the treatment of inflammation, wound healing, skin disease, menorrhagia, diarrhea, jaundice and infection of eyes etc. Micromorphology and physicochemical analysis of the leaves of B.aristata were performed as per WHO and Pharmacopoeial methods. Leaves (4.9cm × 1.8cm) are deep green on dorsal and light green on ventral side. Leaves are in tufts of 5 to 8, phyllotaxy verticillate, simple spiny, lanceolate, toothed, leathery, sessile, acuminate apex and reticulate pinnate venation. Microscopic evaluation of leaves showed biconvex midrib and thick lamina. The epidermal layers of the midrib are thick with small, less conspicuous cells and thick cuticle. The vascular system consists of three large vascular bundles; the median one is small than the two lateral bundles; the bundles are collateral and wedge shaped.  Lamina is made of epidermal layer on the adaxial side with spindle shaped thick walled cells and papillate cuticle. The abaxial epidermis has squarish or rectangular epidermal cells with prominent spiny cuticular outgrowths. Powder microscopy showed the presence of cuticular papillae, anomocytic stomata and spiny outgrowth. Preliminary phytochemical screening of appropriate solvent extracts showed the presence of alkaloids, sterols, tannins, proteins and amino acids, flavonoids, terpenoids, saponin, carbohydrates and absence of glycosides and volatile and fixed oil. Microscopic analysis and other parameters were informative and provide valuable information in the identification, standardization of B.aristata leaves.

    OBJECTIVES: To evaluate the baseline clinical characteristics of juvenile systemic sclerosis (jSSc) patients in the international Juvenile SSc Inception Cohort (jSScC), compare these characteristics between the classically defined diffuse (dcjSSc) and limited cutaneous (lcjSSc) subtypes, and among those with overlap features. METHODS: A cross-sectional study was performed using baseline visit data. Demographic, organ system evaluation, treatment, and patient and physician reported outcomes were extracted and summary statistics applied. Comparisons between dcjSSc and lcSSc subtypes and patients with and without overlap features were performed using Chi-square and Mann Whitney U-tests. RESULTS: At data extraction 150 jSSc patients were enrolled across 42 centers, 83% were Caucasian, 80% female, dcjSSc predominated (72%), and 17% of the cohort had overlap features. Significant differences were found between dcjSSc and lcjSSc regarding the modified Rodnan Skin Score, presence of Gottron's papules, digital tip ulceration, 6 Minute walk test, composite pulmonary and cardiac involvement. All more frequent in dcSSc except for cardiac involvement. DcjSSc patients had significantly worse scores for physician rated disease activity and damage. A significantly higher occurrence of Gottron's papules, musculoskeletal involvement and composite pulmonary involvement, and significantly lower frequency of Raynaud's phenomenon, were seen in those with overlap features. CONCLUSION: Results from a large international jSSc cohort demonstrate significant differences between dcjSSc and lcjSSc patients including more globally severe disease and increased frequency of ILD in dcjSSc patients, while those with lcSSc have more frequent cardiac involvement. Those with overlap features had an unexpected higher frequency of interstitial lung disease
