Hepatocellular carcinoma cells actively communicate with the surrounding stroma and extracellular matrix (ECM). These interactions create an immunosuppressive and pro-tumorigenic environment. Cancer-associated fibroblasts (CAFs) are able to liberate several factors that promote tumor progression and ECM. Metabolic reprogramming and hypoxia in TME influence tumor growth and response to antitumor drugs through bidirectional signaling between tumor and stromal cells. Similarly, activated stellate cells contribute to matrix remodeling and tumor expansion. Tumor-associated macrophages (TAMs), regulatory T cells (Tregs), myeloid-derived suppressor cells (MDSCs), and Kupffer cells can support immune evasion. Recent studies have identified key molecular mediators in these cellular networks. Several targeting strategies show promise in preclinical models. These include immune checkpoint inhibitors (ICIs), immunomodulators, stromal cell modulators, and matrix-degrading agents. However, the effectiveness of conventional therapies remains limited by microenvironmental barriers. Recent progress in the knowledge of TME, nanoparticles, immunomodulators, and even natural-derived molecules with immunoregulatory effects has shown promise in preclinical studies.

A promising therapeutic avenue involves fat browning, the conversion of energy-storing white adipose tissue (WAT) into thermogenic beige fat, which dissipates energy as heat. Since brown fat dissipates more energy than white fat it is commonly characterized by increased mitochondrial biogenesis and the expression of thermogenic genes to enhance energy expenditure. Although fat browning can have different mechanisms, this review focusses on epigenetic mechanisms that underline browning of fat. These epigenetic mechanisms comprise DNA methylation (DNMTs), histone modifications (HDACs, H3K27Me3) and non-coding RNA (miR133, miR26, miR34a) mediated regulation. These epigenetic mechanisms in turn are triggered by diet and exercise, environmental factors such as temperature, obesity and comorbidities such as diabetes and blood pressure. The triggered epigenetic mechanisms in turn trigger genes such as UCP1 which are associated with thermogenesis in adipocytes and hence fat browning. Brown/white fat communicate with neighbouring organs such as liver, heart, kidneys and blood vessels providing protective environment.

We noticed a characteristic papillary, branching or ramifying structure of the amnion on the fetal membrane that we termed \"amniotic papillary folding\" (APF), which was identifiable on microscopic observation, but not macroscopically. Based on the morphological features, APF entirely comprises preexisting amnion and seems to result from misalignment of the amnion. Among 201 placentas submitted for histopathological examination, 88 placentas (43.8 %) displayed APF. From a clinical perspective, APF appeared more frequently in placentas from mothers with hypertensive disorders of pregnancy (HDP). Conversely, APF was significantly less frequent in mothers with gestational diabetes mellitus (GDM). APF tended to be infrequent among mothers with threatened miscarriage, non-reassuring fetal status (NRFS) or fetal growth restriction (FGR). Regarding the relevance to other pathological diagnoses, chorioamnionitis was significantly associated with a reduced frequency of APF, whereas placental infarction was associated with an increased frequency. Our results may imply that the histogenesis of APF is positively associated with retained activity of the fetus in the uterus. APF might be infrequently encountered under conditions in which the fetus is weakened with attenuated mobility, including threatened miscarriage, NRFS, FGR, and most prominently GDM.

However, the detection rate of <em>TP53</em> mutations in ctDNA of HGSOC patients has previously been shown to be inadequate. Given the prevalence of copy number aberrations (CNAs) in HGSOC, this study aimed to improve ctDNA detection by combining <em>TP53</em> sequencing with shallow whole-genome sequencing (sWGS), and to evaluate the correlation with clinicopathological features and survival outcomes. This exploratory, retrospective cohort study included 53 advanced-stage HGSOC patients, comprising 18 treatment-naive patients and 35 patients treated with two neoadjuvant chemotherapy cycles. <em>TP53</em> targeted sequencing was integrated with sWGS (&lt;5x coverage) for CNA estimation using ichor copy number aberration tumor fraction (ichorCNA TF). <em>TP53</em> mutations were detected in 28 patients (52.8 %), and 17 patients (32.1 %) showed positive ichorCNA TF. Combining <em>TP53</em> mutation detection with ichorCNA TF identified 62.3 % (n = 33) of patients as ctDNA-positive, showing a trend towards improved detection compared to <em>TP53</em> mutation alone (p = .063). Treatment-naive patients exhibited higher <em>TP53</em> mutation (72.2 % vs. 42.9 %, p = .043) and ichorCNA TF (66.7 % vs. 14.3 %, p &lt; .001) detection rates compared to chemotherapy-treated patients. No correlations between ctDNA metrics and clinicopathological characteristics or survival outcomes were found. In conclusion, the integration of ichorCNA TF with <em>TP53</em> mutation analysis showed a trend towards improved ctDNA detection in advanced-stage HGSOC patients.
