Abstract
The most common cause of breast cancer-related death is tumor recurrence. To develop more effective treatments, the identification of cancer cell specific malignancy indicators is therefore critical. Lipid droplets are known as an emerging hallmark in aggressive breast tumors. A common technique that can be used for observing molecules in cancer microenvironment is fluorescence microscopy. We describe the design, development and applicability of a smart fluorometer to detect lipid droplet accumulation based on the emitted fluorescence signals from highly malignant (MDA-MB-231) and mildly malignant (MCF7) breast cancer cell lines, that are stained with BODIPY dye. This device uses a visible-range light source as an excitation source and a spectral sensor as the detector. A commercial imaging system was used to examine the fluorescent cancer cell lines before being validated in a preclinical setting with the developed prototype. The outcomes indicate that this low-cost fluorometer can effectively detect the alterations levels of lipid droplets and hence distinguish between "moderately malignant" and "highly malignant" cancer cells. In comparison to prior research that used fluorescence spectroscopy techniques to detect cancer biomarkers, this study revealed enhanced capability in classifying mildly and highly malignant cancer cell lines.

Lipid profile, ox-LDL, and LCAT activity in patients with endometrial carcinoma and type 2 diabetes: The effect of concurrent disease based on a case-control study. Health Sci Rep 2023; 6:e1537. [PMID: 37662543 PMCID: PMC10472909 DOI: 10.1002/hsr2.1537] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 07/23/2023] [Accepted: 08/17/2023] [Indexed: 09/05/2023] Open
Abstract
Background and Aim The role of lecithin: cholesterol acyltransferase (LCAT) and oxidized low-density lipoprotein (ox-LDL) in endometrial cancer (EC) or EC with concurrent type 2 diabetes is still unclear. This study investigated the LCAT activity, ox-LDL, and lipid profile in EC patients with or without type 2 diabetes and compared them with healthy individuals and patients with type 2 diabetes alone. Methods In this cross-sectional, case-control study, 93 female participants were recruited. The participants were divided into four groups, including EC with type 2 diabetes (n = 19), EC without type 2 diabetes (n = 17), type 2 diabetes (n = 31), and healthy controls (n = 26). Sociodemographic information, the LCAT activity, triglyceride (TG), total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and ox-LDL levels were collected. One-way analysis of variance and analysis of covariance, Student's t-test, Mann-Whitney U-test, and χ 2-test were used to compare demographic features and laboratory results among studied groups. Regression analyses were also performed to evaluate the interaction effect between EC and type 2 diabetes on serum LCAT activity. Results The LCAT activity was significantly lower, and ox-LDL levels were significantly higher in all patient groups compared to the healthy controls (p < 0.001). EC patients had significantly lower LCAT activity and higher ox-LDL levels than type 2 diabetes and healthy groups (p < 0.05). Higher levels of TG and lower levels of HDL-C were observed in all patient groups compared to the healthy group (all p < 0.001). Patients with EC and concomitant type 2 diabetes had significantly lower serum LDL-C levels than healthy and type 2 diabetes groups (p < 0.05). Conclusions The combination of EC and type 2 diabetes had a subadditive effect on LCAT activity and ox-LDL level. The lowest LCAT activity and the highest ox-LDL levels were observed in patients with EC and concurrent type 2 diabetes.

Abstract
PURPOSE Plasma atherogenic index (PAI) was shown to be positively correlated with the presence of malignity in patients with suspicious findings for renal cell cancer and colon cancer in reported studies. In this study, we aimed to evaluate whether there is an association with the presence of malignity in patients PI-RADS 3 prostate lesions and PAI. METHODS This retrospective study reviewed the data of 139 patients who underwent transrectal ultrasonography-guided systematic and cognitive fusion prostate biopsy for PI-RADS 3 lesions in multiparametric magnetic resonance imaging. The patients were divided to two groups as malign (n = 33) and benign (n = 106). The association between age, body mass index, comorbidities, smoking status, prostate-specific antigen (PSA), PSA density, free/total PSA, prostate weight, lesion diameter, triglyceride value, high-density lipoprotein-cholesterol value, PAI value data and presence of malignity were investigated by descriptive, multivariate and receiver-operating characteristic (ROC) analysis. RESULTS PSA, PSAD, lesion diameter and PAI value were statistically significantly higher in the malignant group compared to the benign group, and the free/total PSA ratio was lower. In multivariate logistic regression analysis, PSA > 9.9 ng/ml, free/total PSA < 12.1%, lesion diameter > 13.5 mm and PAI > 0.13 were identified as independent risk factors for presence of prostate malignancy. CONCLUSION PAI was found to be a predictive parameter for prostate cancer in PI-RADS 3 prostate lesions. Our study can open new thoughts about PAI as metric to assess the prostate cancer risk.

Abstract
Doxorubicin (DOX) is an anthracycline antibiotic frequently used against a wide range of cancers, including breast cancer. Although the drug is effective as a treatment against cancer, many patients develop heart failure (HF) months to years following their last treatment with DOX. The challenge in preventing DOX-induced cardiotoxicity is that symptoms present after damage has already occurred in the myocardium. Therefore, early biomarkers to assess DOX-induced cardiotoxicity are urgently needed. A better understanding of the mechanisms involved in the toxicity is important as this may facilitate the development of novel early biomarkers or therapeutic approaches. In this review, we discuss the role of high-density lipoprotein (HDL) particles and its components as possible key players in the early development of DOX-induced cardiotoxicity. HDL particles exist in different subclasses which vary in composition and biological functionality. Multiple cardiovascular risk factors are associated with a change in HDL subclasses, resulting in modifications of their composition and physiological functions. There is growing evidence in the literature suggesting that cancer affects HDL subclasses and that healthy HDL particles enriched with sphingosine-1-phosphate (S1P) and apolipoprotein A1 (ApoA1) protect against DOX-induced cardiotoxicity. Here, we therefore discuss associations and relationships between HDL, DOX and cancer and discuss whether assessing HDL subclass/composition/function may be considered as a possible early biomarker to detect DOX-induced cardiotoxicity.

Linking Late Endosomal Cholesterol with Cancer Progression and Anticancer Drug Resistance. Int J Mol Sci 2022; 23:ijms23137206.

Abstract
Cancer cells undergo drastic metabolic adaptions to cover increased bioenergetic needs, contributing to resistance to therapies. This includes a higher demand for cholesterol, which often coincides with elevated cholesterol uptake from low-density lipoproteins (LDL) and overexpression of the LDL receptor in many cancers. This implies the need for cancer cells to accommodate an increased delivery of LDL along the endocytic pathway to late endosomes/lysosomes (LE/Lys), providing a rapid and effective distribution of LDL-derived cholesterol from LE/Lys to other organelles for cholesterol to foster cancer growth and spread. LDL-cholesterol exported from LE/Lys is facilitated by Niemann–Pick Type C1/2 (NPC1/2) proteins, members of the steroidogenic acute regulatory-related lipid transfer domain (StARD) and oxysterol-binding protein (OSBP) families. In addition, lysosomal membrane proteins, small Rab GTPases as well as scaffolding proteins, including annexin A6 (AnxA6), contribute to regulating cholesterol egress from LE/Lys. Here, we summarize current knowledge that links upregulated activity and expression of cholesterol transporters and related proteins in LE/Lys with cancer growth, progression and treatment outcomes. Several mechanisms on how cellular distribution of LDL-derived cholesterol from LE/Lys influences cancer cell behavior are reviewed, some of those providing opportunities for treatment strategies to reduce cancer progression and anticancer drug resistance.

Abstract
RESEARCH QUESTION Does cholesterol metabolism differ in patients with diminished ovarian reserve (DOR) compared to patients with normal ovarian reserve (NOR)? DESIGN The current research included 72 women with NOR and 86 women with DOR. Data on the cholesterol metabolism in granulosa cells of these women were analysed. RESULTS On the day of human chorionic gonadotrophin injection, serum oestradiol and progesterone in the DOR group were significantly lower than in the control group (P < 0.001). There were no significant differences in serum concentrations of total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein between the NOR and DOR groups. The cholesterol-regulated gene SCAP in granulosa cells from women with DOR was down-regulated (P = 0.024). Cholesterol synthesis and transport genes (e.g. IDI1, FDFT1, CYP51A1, SRB1 and STARD1) were also significantly decreased (P = 0.026, P = 0.044, P = 0.049, P = 0.004 and P < 0.001, respectively). In granulosa cells of patients with DOR, cholesterol-related substances such as coprostanone, 11A-acetoxyprogesterone and 17α-hydroxyprogesterone were significantly reduced (P = 0.0008, P = 0.0269, P = 0.0337, respectively). CYP19A1, a key steroidogenesis gene, was significantly reduced (P = 0.009). 17α-hydroxyprogesterone and oestradiol decreased (P = 0.004 and P = 0.039, respectively). CONCLUSION Decreased cholesterol metabolism affecting steroid hormone synthesis in granulosa cells might be a possible mechanism for DOR.

Abstract
Background Cancer patients often exhibit chemotherapy-associated changes in serum lipid profiles, however, their prognostic value before and after adjuvant chemotherapy on survival among non-small-cell lung cancer (NSCLC) patients is unknown. Methods NSCLC patients undergoing radical resection and subsequent adjuvant chemotherapy from 2013 to 2017 at Sun Yat-sen University Cancer Center were retrospectively reviewed. Fasted serum lipid levels were measured before and after chemotherapy. The optimal lipid cut-off values at baseline and fluctuation were determined using X-tile™. The fluctuations in serum lipid levels and disease-free survival (DFS) were assessed. Results Serum cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), triglyceride, apolipoprotein (Apo) A-I, and ApoB all significantly increased after adjuvant chemotherapy. X-tile determined 1.52 mmol/L of HDL-C and 0.74 g/L of ApoB as the optimal cut-off values before chemotherapy. Patients with HDL-C ≥ 1.52 mmol/L (median DFS: not reached vs. 26.30 months, P = 0.0005) and a decreased HDL-C level after adjuvant chemotherapy (median DFS: 80.43 vs. 26.12 months, P = 0.0204) had a longer DFS. An HDL-C level that increased by ≥ 0.32 mmol/L after chemotherapy indicated a worse DFS. A high baseline ApoB level were associated with a superior DFS. In the univariate analysis and the multivariate Cox analyses, a high baseline HDL-C level and a HDL-C reduction after adjuvant chemotherapy were independent indicators for superior DFS. High baseline HDL-C was related to N0-1 stage (χ2 = 6.413, P = 0.011), and HDL-C fluctuation was significantly correlated with specific chemotherapy regimens (χ2 = 5.002, P = 0.025). Conclusions Adjuvant chemotherapy increased various lipid levels in resected NSCLC patients. A higher HDL-C level before chemotherapy and a reduced HDL-C level after adjuvant chemotherapy were independent predictors of longer DFS in patients with curable NSCLC.

Abstract
We have developed a method for studying the lipid profile of saliva, combining preliminary extraction and IR spectroscopic detection. The case-control study involved patients with a histologically verified diagnosis of breast and prostate cancer and healthy volunteers. The comparison group included patients with non-malignant pathologies of the breast (fibroadenomas) and prostate gland (prostatic intraepithelial neoplasia). Saliva was used as a material for biochemical studies. It has been shown that the lipid profile of saliva depends on gender, and for males it also depends on the age group. In cancer pathologies, the lipid profile changes significantly and also depends on gender and age characteristics. The ratio of 1458/1396 cm-1 for both breast and prostate cancer has a potential diagnostic value. In both cases, this ratio decreases compared to healthy controls. For prostate cancer, the ratio of 2923/2957 cm-1 is also potentially informative, which grows against the background of prostate pathologies. It is noted that, in all cases, changes in the proposed ratios are more pronounced in the early stages of diseases, which increases the relevance of their study in biomedical applications.

Abstract
Multiple myeloma (MM) is an incurable neoplastic hematologic disorder characterized by malignant plasma cells, mainly in the bone marrow. MM is associated with multiple factors, such as lipid metabolism, obesity, and age-associated disease development. Although, the precise pathogenetic mechanisms remain unknown, abnormal lipid and lipoprotein levels have been reported in patients with MM. Interestingly, patients with higher APOA1 levels, the major apolipoprotein of high density lipoprotein (HDL), have better overall survival. The limited existing studies regarding serum lipoproteins in MM are inconclusive, and often contradictory. Nevertheless, it appears that deregulation of the lipoprotein transport system may facilitate the development of the disease. Here, we provide a critical review of the literature on the role of lipids and lipoproteins in MM pathophysiology. We also propose novel mechanisms, linking the development and progression of MM to the metabolism of blood lipoproteins. We anticipate that proteomic and lipidomic analyses of serum lipoproteins along with analyses of their functionality may improve our understanding and shed light on novel mechanistic aspects of MM pathophysiology.

Abstract
Lipids play an important role in processes such as the formation of membrane cells or in steroidogenesis, where androgens which stimulate the proliferation of prostate cancer (PCa) cells are produced. Previous studies presented links between cholesterol (CHOL) and PCa and concluded that cholesterol homeostasis changes in PCa patients during treatment and with age. This study further examines the correlation between the lipid profile, the treatment used, and the subjects’ age. Ninety-one subjects (Group 1: >69 years; Group 2: ≤69) histopathologically diagnosed with PCa were tested. Total CHOL, triglycerides (TG), high-density lipoprotein (HDL), low density lipoprotein (LDL), and very low density lipoprotein (VLDL) were assessed from blood taken before the entire course of radiotherapy (RT) and in 3-month intervals after the treatment was completed, for up to 4 years (range: palliative and radical). In all the subjects, the CHOL decreased over time after RT (p = .0445) with a simultaneous increase of prostate specific antigen (PSA) concentration (p = .0366). A faster decrease of HDL was observed with a higher concentration of PSA (p = .0053) and Gleason score (p = .0304). In all the subjects, the HDL decreased after RT (p = .0159) but in the older palliative group the HDL decrease progressed more slowly (p = .0141). It could be stated, that after radical therapy TG levels tended to be consistently higher among younger men relative to the elderly (p = .0151). But it was observed that RT treatment could lead to a decrease in the lipid serum concentration.

Abstract
Background: The clinical significance of plasma lipoprotein levels in the diagnosis and prognosis of certain diseases is known fact. Some studies have reported different and contradictory levels of blood lipoproteins in cancer patients. Therefore, we decided to compare lipid profiles in patients with basal cell carcinoma (BCC) and healthy individuals. Materials and Methods: In this case-control study, lipid biomarkers in blood plasma of 64 patients with BCC compared with biomarkers in 64 healthy subjects. According to including criteria's both group selected. 5 cc blood samples taken after 8–12 h of fasting. Ultimately, the diagnosis of biopsy samples confirmed by the dermatopathologist. The information data entered into the PASS II software and then characterized by a descriptive and analytical statistics of the lipid profile. The role of the related factors was assessed by two sample t-test power analysis. Results: In this research, mean age of patient group and the healthy one was 67.13 ± 11.33 and 64.31 ± 6.98, respectively. The average amount of triglyceride, cholesterol, high density lipoprotein (HDL) and low density lipoprotein in the BCC patients were 147.97 ± 87.11 mg/dl, 188.25 ± 38.90 mg/dl, 61.98 ± 18.61 mg/dl and 95.98 ± 31.69 mg/dl, respectively, whereas these amounts in the control group were 137.34 ± 61.41 mg/dl, 173.22 ± 38.79 mg/dl, 42.34 ± 7.83 mg/dl and 106.44 ± 35.17 mg/dl, respectively. There were statistically significant differences between cholesterol and HDL in patients with BCC and healthy controls, respectively (P = 0.030) (P < 0.001). Conclusion: It seems that changes in lipid profile can help as a diagnostic marker for detecting cancer like BCC. Although this change could be different in lipid markers and also among different types of cancer.

Abstract
Introduction Dyslipidaemia contributes to the occurrence of colorectal cancer (CRC). We hypothesized that qualitative changes of lipoproteins are associated with the risk for CRC development. This study analyses low-density lipoprotein (LDL) and high-density lipoprotein (HDL) diameters, as well as distribution of LDL and HDL subclasses in patients with CRC, with an aim to determine whether advanced lipid testing might be useful in predicting the risk for the onset of this malignancy. Materials and methods This case-control study included 84 patients with newly diagnosed CRC and 92 controls. Gradient gel electrophoresis was applied for separation of lipoprotein subclasses and for LDL and HDL diameters determination. Lipid parameters were measured using routine enzymatic methods. Results Total cholesterol, HDL and LDL-cholesterol were significantly lower in CRC patients compared to controls (4.47 mmol/L vs. 5.63 mmol/L; 0.99 mmol/L vs. 1.27 mmol/L; 2.90 mmol/L vs. 3.66 mmol/L; P < 0.001, respectively). Patients had significantly smaller LDL (25.14 nm vs. 26.92 nm; P < 0.001) and HDL diameters (8.76 nm vs. 10.17 nm; P < 0.001) and greater proportion of small, dense LDL particles (54.0% vs. 52.9%; P = 0.044) than controls. Decreased LDL and HDL diameters were independent predictors of CRC (OR = 0.5, P = 0.001 and OR = 0.5, P = 0.008, respectively), and alongside with age and HDL-cholesterol concentrations formed the optimal cost-effective model, providing adequate discriminative abilities for CRC (AUC = 0.89) and correct patients classification (81%). Conclusions Patients with CRC have decreased LDL and HDL diameters and increased proportion of smaller particles. LDL and HDL diameters determination could be useful in assessing the risk for CRC development.

Immunohistochemical Labeling of Low-Density Lipoprotein Receptor and Scavenger Receptor Class B Type 1 Are Increased in Canine Lymphoma. Front Vet Sci 2019; 5:340.

Abstract
Altered lipid metabolism is a well-documented hallmark of neoplastic transformation and impacts disease progression. Two major lipoprotein receptors, the low-density lipoprotein receptor (LDL-R) and scavenger receptor class B, type 1 (SR-BI) are overexpressed in a number of cancer types in people. These receptors serve to deliver cholesterol to the tumor cells and have been used to target drug therapies. In this study, we performed a retrospective analysis of LDL-R and SR-B1 expression in canine lymphoma using archived formalin-fixed tissue samples. Cases were immunophenotyped and classified according to World Health Organization (WHO) standards prior to immunostaining for the LDL_R and SR-B1. A total of 45 cases were evaluated; 21 high grade B (HGB), 11 low grade B (LGB), 7 high grade T (HGT), and 6 low grade T (LGT) lymphomas. One sided Wilcoxon rank sum tests were used to compare staining intensity between neoplastic and hyperplastic lymphoid tissue. The relationships between histological score and tumor grade and score and stage at presentation were assessed using non-parametric Kruskal-Wallis tests. Neoplastic lymphoid tissue expressed higher levels of both receptors compared to reactive lymph nodes. Median LDL-R score was 85.0 (interquartile range = 101.7), Median SR-B1 score was 209.0 (interquartile range 105.2). No relationship between LDL-R or SR-B1 staining score and tumor grade or phenotype was found. Serum cholesterol concentration was compared between dogs with high and low grade tumors using a two sample T-test, and correlations between cholesterol concentration and histological score, and between the score for the two receptors were determined using a Spearman correlation. The high expression level of these lipoprotein receptors on most of the tumors could underlie the lack of relationship between score and tumor grade. The overexpression of LDL-R and SR-B1 in canine lymphoma holds therapeutic potential particularly in dogs that overexpress one or both of these receptors, and this warrants further investigation.

Abstract
Background PCSK9 regulates low-density lipoprotein cholesterol (LDLc) level and has been implicated in hypercholesterolemia. Aberrant plasma lipid profile is often associated with various cancers. Clinically, the relationship between altered serum lipid level and hepatocellular carcinoma (HCC) has been documented; however, the underlying cause and implications of such dyslipidemia remain unclear. Methods The present study includes the use of HepG2 tumor xenograft model to study the potential role of glucose (by providing 15% glucose via drinking water) in regulating PCSK9 expression and associated hypercholesterolemia. To support in vivo findings, in vitro approaches were used by incubating HCC cells in culture medium with different glucose concentrations or treating the cells with glucose uptake inhibitors. Impact of hypercholesterolemia on chemotherapy was demonstrated by exogenously providing LDLc followed by appropriate in vitro assays. Results We observed that serum and hepatic PCSK9 level is decreased in mice which were provided with glucose containing water. Interestingly, serum and tumor PCSK9 level was upregulated in HepG2-tumor-bearing mice having access to water containing glucose. Additionally, elevated LDLc is detected in sera of these mice. In vitro studies indicated that PCSK9 expression was increased by high glucose availability with potential involvement of reactive oxygen species (ROS) and sterol regulatory element binding protein-1 (SREBP-1). Furthermore, it is also demonstrated that pre-treatment of cells with LDLc diminishes cytotoxicity of sorafenib in HCC cells. Conclusion Taken together, these results suggest a regulation of PCSK9 by high glucose which could contribute, at least partly, towards understanding the cause of hypercholesterolemia in HCC and its accompanied upshots in terms of altered response of HCC cells towards cancer therapy.

Abstract
Smoking-related biomarkers for lung cancer and other diseases are needed to enhance early detection strategies and to provide a science base for tobacco product regulation. An untargeted metabolomics approach by ultra-performance liquid chromatography-quadrupole-time of flight mass spectrometry (UHPLC-Q-TOF MS) totaling 957 assays was used in a novel experimental design where 105 current smokers smoked two cigarettes 1 h apart. Blood was collected immediately before and after each cigarette allowing for within-subject replication. Dynamic changes of the metabolomic profiles from smokers' four blood samples were observed and biomarkers affected by cigarette smoking were identified. Thirty-one metabolites were definitively shown to be affected by acute effect of cigarette smoking, uniquely including menthol-glucuronide, the reduction of glutamate, oleamide, and 13 glycerophospholipids. This first time identification of a menthol metabolite in smokers' blood serves as proof-of-principle for using metabolomics to identify new tobacco-exposure biomarkers, and also provides new opportunities in studying menthol-containing tobacco products in humans. Gender and race differences also were observed. Network analysis revealed 12 molecules involved in cancer, notably inhibition of cAMP. These novel tobacco-related biomarkers provide new insights to the effects of smoking which may be important in carcinogenesis but not previously linked with tobacco-related diseases. © 2016 Wiley Periodicals, Inc.

Abstract
BACKGROUND The phenomenon of chemotherapy-related lipid alterations has been reported based on a small number of patients and varies among different cancers. However, little is known about these alterations in colorectal cancer (CRC) patients. RESULTS Patients in cohort 1, but not in cohort 2, exhibited significantly increased cholesterol, triglyceride, HDL-C, and ApoA-I levels, and decreased LDL-C and ApoB levels after adjuvant chemotherapy. Patients with chemotherapy-related HDL-C elevation exhibited better 3-year DFS (84.5% vs. 73%, P = 0.001) and 7-year OS (82% vs. 70%, P = 0.002) than those without. Similarly, the 3-year DFS (83.3% vs. 77.6%, P = 0.008) and 7-year OS (81% vs. 74.6%, P = 0.040) were superior in chemotherapy-related ApoA-I elevation patients. However, only HDL-C elevation remained an independent prognostic value in the multivariate Cox model. METHODS Eight hundred fifty-one CRC patients with curative-intent resection were retrospectively analyzed. Six hundred sixty-seven receiving fluoropyrimidine-based adjuvant chemotherapy for more than 3 months were enrolled in cohort 1. The lipid alterations before and after chemotherapy were studied. Simultaneously, 184 patients not treated with chemotherapy (cohort 2) were included as a control for the comparisons of lipids alterations within 1 month after resection and at half-year follow-up. Furthermore, these significant alterations were investigated with respect to the prognostic value of disease-free survival (DFS) and overall survival (OS). An internal validation was performed. CONCLUSION We observed significant changes in the levels of various lipids in CRC patients receiving adjuvant chemotherapy. Furthermore, chemotherapy-related HDL-C elevation was determined to be an independent prognostic indicator for superior DFS and OS.

Abstract
BACKGROUND Different types of cancer cells are previously shown to accumulate intracellular cholesterol. However, the data on intracellular cholesterol levels in leukemia cells provide contradictory evidence. Various previous works indicate either increase, decrease or no difference in total cholesterol levels between leukemia cells and healthy peripheral blood mononuclear cells (PBMCs). METHODS We studied the intracellular cholesterol levels in acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) cells and compared with that in PBMCs from the healthy subjects. RESULTS We observed that the PBMCs from AML (n=7) and ALL (n=7) patients displayed significantly lower intracellular levels of total cholesterol in comparison to PBMCs from the healthy subjects (n=26). Consistent with the patient data the ALL (CCRF-CEM and MOLT-3) and AML (KG-1 and THP-1) cell lines also displayed significantly lower intracellular levels of total cholesterol. We confirmed this observation using multiple methodological approaches. Both ALL and AML cell lines also displayed significantly lower levels of free cholesterol and cholesteryl ester contents in comparison to normal hematopoietic cells. We observed that >90% of the total cholesterol in leukemia cells as well as in normal PBMCs was present in the form of cholesteryl esters. It was also observed that the lower levels of cholesterol in leukemia cells are not affected by exogenous cholesterol availability. CONCLUSIONS Present study provides convincing evidence to prove that the cellular free cholesterol and cholesteryl ester content is significantly reduced in leukemia cells in comparison to normal hematopoietic cells in circulation. Moreover, it was shown that the lower levels of cholesterol in leukemia cells are not affected by exogenous cholesterol availability.

Abstract
Hypocholesterolemia has been observed in patients with cancers of various organs; however the potential role of alterations in serum lipid profile in oral cancer remains controversial. Hence, this study aimed to evaluate the serum lipid profile in oral squamous cell carcinoma (OSCC) and its prognostic significance. Ninety untreated OSCC patients, who reported to the craniofacial unit for treatment between 2011 and 2014, were identified to obtain clinicopathological data and preoperative blood investigations including lipid profile. The fasting blood lipid profile, including total cholesterol (TC), triglyceride (TG), high density lipoprotein (HDL), and low density lipoprotein (LDL), was evaluated using a fully automated biochemistry analyser. Data were analyzed statistically using the Student's t-test, analysis of variance, and post hoc tests. Statistically significant decreases in serum TC, HDL, and LDL levels were observed in OSCC patients as compared to healthy controls (P<0.05). There was no statistically significant difference in mean lipid profile values in terms of stage, grade, or lymph node metastasis. This study identified changes in lipid profiles in OSCC. The results suggest that during the development and progression of OSCC, levels of serum lipids are decreased. A review of the literature confirmed that OSCC patients exhibit aberrant serum lipid patterns.

Abstract
BACKGROUND Previous studies appreciate the leukemia-associated alterations in plasma lipid profiles but fail to provide a consistent pattern of lipid anomalies in leukemia patients. These inconsistencies could be due to overlooking the effects of related confounding risk-factors and comorbidities. METHODS The plasma lipid profiles of acute-leukemia and control groups were compared. RESULTS We observed that acute lymphocytic leukemia (ALL) patients display significantly higher triglycerides and very low-density lipoproteins, whereas, acute myeloid leukemia (AML) patients display significantly lower high-density lipoproteins. To assess the confounding effects of related risk factors gender-, age- and BMI-based analyses were performed. We observed that the aforementioned significant differences in the lipid profiles of leukemia patients were restricted to female participants of the respective groups. Moreover, a significant decrease in total cholesterol and low-density lipoprotein levels was observed only in male participants of the AML population. Various age-specific trends in plasma lipid profile of the leukemia patients were also observed. BMI-based analysis did not display many significant differences from the overall analyses. In addition to comparing the absolute values of plasma lipids in leukemia and control groups we also compared and observed significant differences in prevalence of various isolated- and mixed-dyslipidemias in these groups. CONCLUSIONS These findings may help in outlining the prevalence and types of dyslipidemia in leukemia patients that may emerge as diagnostic/prognostic factors for the management of acute leukemia.
