- Green tea (GT) is widely recognized for its metabolic effects, but the influence of biological sex and housing temperature on its response during diet-induced obesity remains incompletely understood. Male and female C57BL/6 mice were housed at standard temperature (22 °C) or thermoneutrality (28 °C), fed a standard diet (SD) or high-fat diet (HFD), and, after obesity induction, received GT by oral gavage at 500 mg/kg, five days per week, for 12 weeks. Longitudinal mixed-effects modeling and endpoint factorial ANCOVA showed that GT attenuated HFD-associated body weight gain in both sexes and at both housing temperatures. The significant Diet × GT interaction indicated that the effect on final body weight depended primarily on dietary condition, whereas no statistical evidence was found that the overall endpoint response differed according to sex or housing temperature. Plasma proteomic profiling of HFD + GT mice housed at 22 °C identified extensive remodeling in both sexes, with comparable numbers but distinct identities and directions of change among differentially abundant proteins. Candidate proteins were associated with lipid metabolism (APOC2 and ANXA2), inflammatory processes (CD68, CSF1, and SAA4), and neuroimmune-related functions (GRN), revealing distinct sex-dependent molecular patterns. Complementary hypothalamic immunohistochemistry showed that GT attenuated HFD-associated increases in GFAP and IBA1 immunoreactivity. The reduction in astrocytic GFAP immunoreactivity was particularly pronounced in males housed at 22 °C, whereas the decrease in microglial IBA1 immunoreactivity was broadly consistent across the comparisons evaluated. Together, these findings demonstrate that GT attenuates HFD-associated weight gain and hypothalamic glial immunoreactivity while inducing extensive, sex-dependent plasma proteome remodeling. These findings highlight dietary context as a major determinant of the physiological response to GT and identify biological sex and housing temperature as important variables shaping its molecular effects. SIGNIFICANCE: This study shows that green tea attenuates HFD-associated body weight gain and hypothalamic glial immunoreactivity while inducing sex- and temperature-sensitive plasma proteomic responses. By integrating physiological, proteomic, and histological analyses, we identified molecular- and tissue-level changes associated with lipid metabolism, inflammation, and glial reactivity. The findings indicate that dietary status is a major determinant of the physiological response to green tea, whereas sex and housing temperature shape the associated molecular signatures. These results emphasize the importance of experimental context in preclinical nutraceutical research and support further investigation of green tea-derived compounds in obesity-associated metabolic and neuroimmune alterations. - Source: PubMed

Previous studies have indicated that apolipoprotein C-II (APOC2) is involved in the immune microenvironment of several malignancies and is upregulated in breast cancer; however, the molecular mechanisms through which APOC2 regulates the immune microenvironment in TNBC remain poorly understood. In the present study, we found that APOC2 was upregulated in TNBC tissues and was negatively correlated with M1 macrophage infiltration. APOC2 overexpression in 4 T1 cells promoted tumor progression by enhancing cell proliferation, migration, and invasion, while suppressing M1 macrophage polarization. In addition, KLHL1, a substrate adaptor for the Cullin3-RING E3 ubiquitin ligase complex, was found to interact with APOC2, and KLHL1 overexpression reversed the biological effects induced by APOC2. Mechanistically, KLHL1 promoted APOC2 protein degradation through the ubiquitin-proteasome pathway, thereby enhancing M1 macrophage polarization and suppressing the malignant behavior of tumor cells. Finally, in vivo xenograft experiments demonstrated that APOC2 reduced M1 macrophage polarization and increased tumor weight and volume, whereas KLHL1 overexpression counteracted the oncogenic effects of APOC2. Collectively, these findings reveal that activation of the KLHL1/APOC2 axis enhances M1 macrophage polarization and inhibits TNBC progression, providing novel insights into the immune regulatory mechanisms underlying TNBC development. - Source: PubMed

He ZiranZhang ZhenhuaDing LiLong ShanYang LiuHu CeLong MengXueLiu Zhiqiang - Data on the interaction between dietary patterns, single nucleotide polymorphisms (SNPs), and cardiometabolic markers remain limited in genetically admixed populations, particularly among individuals with established cardiovascular disease (CVD). This study aimed to evaluate how SNPs modulate the effects of dietary interventions on apolipoprotein concentrations (A-I, A-II, B, C-II, C-III, and E) in Brazilians undergoing secondary cardiovascular prevention. - Source: PubMed

In this study, we aim to characterise the clinicopathological patterns and identify potential prognostic factors in renal amyloidosis at an Australian tertiary referral centre over a decade. A total of 63 biopsy-diagnosed cases of renal amyloidosis from 2011 to 2021 were retrospectively reviewed. Cases were initially subtyped by immunofluorescence and immunohistochemistry. Mass spectrometry was performed when rare subtypes were suspected. Histological characteristics were correlated with clinical parameters at the time of biopsy. The primary outcome was severe renal impairment (SRI), defined as an estimated glomerular filtration rate (eGFR) <10 mL/min/1.73 m or commencement of renal replacement therapy. Amyloid light chain (AL) amyloidosis was the most common subtype (79%), followed by amyloid A (AA) (11%), and the rare subtypes included amyloid leukocyte cell-derived chemotactic factor-2 (3.2%); amyloid transthyretin wild-type (1.6%); amyloid apolipoprotein C-II (1.6%); amyloid fibrinogen (1.6%); and amyloid gelsolin amyloidosis (1.6%). Patients with AA amyloidosis were younger than those with other subtypes. The classic histological patterns of common and rare amyloid subtypes, as described in the literature, were replicated in our cohort. Interstitial fibrosis and tubular atrophy had a strong correlation with baseline eGFR and were important prognostic factors for SRI. Nephrotic-range proteinuria showed a trend towards SRI, but amyloid subtype (AL vs AA vs other) did not stratify outcome. Most AL amyloidosis cases (69%) were confirmed to be monoclonal gammopathy of undetermined significance, with a smaller proportion showing an underlying haematological malignancy. All patients with AA subtype had an underlying chronic inflammatory disease condition. We demonstrate classic histopathological features of common and rare subtypes of renal amyloidosis in an Australian cohort. Histological markers at biopsy, indicative of chronic renal damage, have value as prognostic factors. - Source: PubMed

Given limited access to genetic testing and frequent negative results in clinically consistent cases, clinical scores and lipid ratios have been proposed to predict FCS. - Source: PubMed
