Abstract
BACKGROUND AND OBJECTIVE Hyperthermic intraperitoneal chemotherapy (HIPEC) is still controversial in ovarian cancer (OC) management. Doubts are related mainly to HIPEC effectiveness, but also to its safety. European Society of Medical Oncology and European Society of Gynecologic Oncology do not consider HIPEC as a standard of care. Opposite to European recommendations, National Comprehensive Cancer Network found HIPEC as a treatment option in patients undergoing interval debulking surgery in first-line treatment. This may be confusing for oncologists in clinical practice. The aim of this narrative review is to present literature review focusing on efficacy, confounding factors, complications and immunological issue of HIPEC in OC management. METHODS PubMed was searched for meta-analyses, randomized trials, observational studies, experimental studies to outline the role of HIPEC in OC management since January 2015 until August 2023. Keywords included "hyperthermic intraperitoneal chemotherapy", "HIPEC", "ovarian cancer", "immune response". References from full-text articles were screened for additional studies. KEY CONTENT AND FINDINGS Most meta-analyses found that HIPEC improved survival in patients with OC and none of the meta-analyses showed that addition HIPEC to surgery was associated with a worse treatment outcome compared to surgery alone. Positive effect on treatment outcome was found more common in first-line treatment than recurrent disease. Positive effect on treatment outcome was more common in first-line treatment (especially during interval debulking surgery) than recurrent disease. HIPEC efficacy can be affected by patients' characteristics (BRCA status, platinum sensitivity), cytostatic type and dose, intensity of hyperthermia and peritoneal flow characteristics. Apart from strict cytotoxic effect, HIPEC can induce anti-cancer immune response. CONCLUSIONS Although factors confounding HIPEC efficacy are not well-defined, survival improvement, related to addition HIPEC to surgery in OC, was observed. Future studies should focus on determining a subgroup of patients, who benefit from HIPEC. This will contribute to the unification of European and American recommendations.

Abstract
Immune checkpoint inhibitors (ICIs) are utilised in treating non-small cell lung cancer (NSCLC) by enhancing the immune response against cancer cells. However, they are not effective against cancers with certain genetic alterations. A recent study by Mota et al. focussed on understanding why ALK+ NSCLC cancers are immune cold and making them more receptive to ICIs using a vaccine-based approach. The study highlighted cell-specific differences in the presentation of immunogenic peptides and the location of tumours as factors in the poor immune response. Vaccines based on ALK peptides improved immune response, and when combined with ICIs, this led to a striking improvement in survival in a mouse model of ALK+ NSCLC.

Abstract
Rapid and continuing advances in biomarker testing are not being matched by take-up in health systems, and this is hampering both patient care and innovation. It also risks costing health systems the opportunity to make their services more efficient and, over time, more economical. This paper sets out the potential of biomarker testing, the unfolding precision and range of possible diagnosis and prediction, and the many obstacles to adoption. It offers case studies of biomarker testing in breast, ovarian, prostate, lung, thyroid and colon cancers, and derives specific lessons as to the potential and actual use of each of them. It also draws lessons about how to improve access and alignment, and to remedy the data deficiencies that impede development. And it suggests solutions to outstanding issues - notably including funding and the tangled web of obtaining reimbursement or equivalent coverage that Europe's fragmented health system implies. It urges a European evolution towards an initial minimum testing scenario, which would guarantee universal access to a suite of biomarker tests for the currently most common conditions, and, further into the future, to an optimum testing scenario in which a much wider range of biomarker tests would be introduced and become part of a more sophisticated health system articulated around personalised medicine. For exploiting genomics to the full, it argues the need for a new policy framework for Europe. Biomarker testing is not an issue that can be treated in isolation, since the purpose of testing is to improve health. Its use is therefore always closely linked to specific health challenges and needs to be viewed in the broader policy context in the EU and more widely. The paper is the result of extensive engagement with experts and decision makers to develop the framework, and consequently represents a wide consensus of views on how healthcare systems should respond from push and pull factors at local, national and cross-border and EU level. It contains strong views and clear recommendations springing from the convictions of patients, clinicians, academics, medicines authorities, HTA bodies, payers, the diagnostic, pharmaceutical and ICT industries, and national policy makers.

Abstract
Chronic rhinosinusitis (CRS) is a frequent disease with high social impact and multifactorial pathogenesis. Recently, the bitter taste receptor TAS2R38 has been described to play a role in upper airway innate mucosal defense. The aim was to determine the localization and expression of the TAS2R38 in the selected cell lines and tissue collected from patient suffered from CRS as well as to correlate the results with clinical data. Moreover, the purpose was the estimation of the TAS2R38 distribution changes during acute and CRS. Forty-two patients undergoing nasal surgery were enrolled in the study. The TAS2R38 expression was assessed in the collected tissues using immunohistochemistry and immunocytochemistry methods. The western blot analysis was performed on human cell lines HeLa, MCF7, MDA-MB-231 to assess the location of the TAS2R38 protein. Moreover, the HeLa cell line was used as a model of acute inflammation induces by lipopolysaccharide. Immunohistochemistry analysis displayed a statistically significant difference of TAS2R38 level in the patients with CRS compared to healthy control and was different in CRS with and without nasal polyps. The results showed the abundance of TAS2R38 receptor in the cell nucleus in patients with CRS and cell lines. The variance in TAS2R38 receptor expression in two CRS types suggests their different pathogenesis. The first time in literature, we confirmed the presence of plasma membrane TAS2R38 receptor in the cell nuclei in CRS as well as in cell lines, what strongly suggests the different than membrane TAS2R38 function.

Abstract
<b>Background:</b> Chronic rhinosinusitis (CRS) is one of the most common health complaints affecting 15% of the world's population. Recent reports confirm the participation of sensory organs in the defense process against pathogenic microorganisms. The bitter taste receptor TAS2R38 is described to play a role in the upper airway defense system. <br><b>Purpose:</b> The purpose of this study was to assess the function of the bitter taste receptor in correlation with the severity of CRS, sensory organ disorders and allergic reaction. <br><b>Material and method: </b>The study contained 100 patients undergoing nasal surgery, divided into two groups: CRS with and without nasal polyps. The control group consisted of patients undergoing septoplasty after excluding rhinosinusitis. Sinus mucosa samples obtained during surgery were used to assess TAS2R38 expression using immunohistochemistry. The IgE level was indicated from blood samples collected from patients. The Sniffin' Sticks Test was performed. <br><b>Results:</b> CRS patients had higher expression of TAS2R38 receptor compared to controls (p = 0.0175). A statistically significantly higher TAS2R38 H-score in nasal mucosa was found among patients with a higher inflammation process in CT scan (p = 0.001), higher IgE level (p = 0,04) and an abnormal result of the Sniffin' Sticks Test. <br><b>Conclusions: </b>Patients with CRS had significant TAS2R38 receptor overexpression correlating with the severity of inflammatory changes in CT scans, abnormal perception of smells and higher IgE level. A cumulative impact was found between the inflammatory changes, smell disfunction and the severity of subjective symptoms of CRS (according to EPOS) and the intensity of cell staining (index H-score).

Abstract
BACKGROUND The SWI/SNF (SWItch/sucrose non-fermentable) chromatin remodeling complex enables glucocorticoid receptor (GR) and vitamin D receptor (VDR) to function correctly and is engaged in inflammation response. The SWI/SNF may play an important role in chronic rhinosinusitis (CRS). OBJECTIVES The aim of this study was to assess the following: 1) the gene and protein expression of the SWI/SNF complex subunits in sinonasal mucosa; 2) relation of SWI/SNF complex and VDR expression; and 3) correlation with clinical data. MATERIAL AND METHODS The study population consisted of 52 subjects with CRS without nasal polyps, 55 with CRS with nasal polyps and 59 controls. The SWI/SNF protein expression level was analyzed in immunohistochemical (IHC) staining. Human nasal epithelial cells (HNECs) was stimulated using lipopolysaccharide (LPS), Staphylococcal enterotoxin B (SEB) and vitamin D3 (vitD3) in vitro. The transcript level of the SWI/SNF subunits was measured with polymerase chain reaction (PCR). RESULTS In the control group, the intensity of the IHC staining for SWI/SNF subunits was significantly higher than in both groups of patients with CRS (p < 0.05). A positive correlation of the SWI/SNF protein expression was noticed with VDR expression level (p < 0.043). Association between SWI/SNF protein expression level and allergy, neutrophils and body mass index (BMI) has been observed (p < 0.05). The decreased transcript level of the SWI/SNF subunits genes in HNECs was observed after LPS stimulation and increased after vitD3 stimulation. CONCLUSIONS The SWI/SNF complex may influence CRS through steroid hormone signaling and VDR. Thus, modification in therapy may be mandatory in patients with CRS and altered SWI/SNF signaling, reflecting resistance to steroids treatment.

Abstract
BACKGROUND Bitter taste receptors (T2Rs), especially T2R38s appear as innovative regulators of innate immunity in the respiratory system. The single nucleotide polymorphisms (SNPs) in TAS2R38 gene may contribute to individual differences in susceptibility to respiratory infections especially chronic rhinosinusitis (CRS). TAS2R38 genotypes distribution varies by geographic region, race and ethnicity. The aim of the preliminary study was the identification of SNPs in TAS2R38 encoding genes in Polish patients with CRS and finding potential correlation with CRS phenotypes. MATERIAL AND METHODS The preliminary study contained 20 CRS patients undergoing functional endoscopic sinus surgery (FESS). Fresh sinus mucosa (SM) was obtained during FESS in CRS patients. Patients were genotyped for TAS2R38 using Sanger method and the genotype occurrences of the clinically recalcitrant CRS cohort was evaluated. Analysis of TAS2R38 expression in SM of CRS patients was performed using immunohistochemistry (IHC). RESULTS T2R38 was highly expressed in SM of CRS patients. Patients with CRS demonstrated both common genotypes PAV, AVI. The heterozygotes frequency (AVI/PAV) was the highest. The protective genotype (PAV/PAV) was noticed in the lowest frequency and connected with lower average value of CT score compare to AVI/AVI genotypes (p=0.01). CONCLUSIONS The work presented in this study provides the hypothesis that airway bitter T2Rs are an innovative sphere of human respiratory innate protection. TAS2R38 polymorphism may influence the susceptibility to CRS. The AVI haplotypes are an independent risk factors for CRS. Additionally, the bitter taste receptors and related signalling pathways might create an unique group of therapeutic targets to treat CRS.

Abstract
HAX-1, a multifunctional protein involved in the regulation of apoptosis, cell migration, and calcium homeostasis, binds the 3' untranslated region motifs of specific transcripts. This suggests that HAX-1 plays a role in post-transcriptional regulation, at the level of mRNA stability/transport or translation. In this study, we analyze in detail HAX-1 colocalization with processing bodies (P-bodies) and its dependence on mRNA availability. Endogenous P-body markers DCP1 and Rck/p54 were shown to colocalize with endogenous HAX-1, but in case of the overexpressed proteins, only DCP1 displayed unperturbed colocalization with HAX-1. HAX-1 colocalization with DCP1 was observed in most of the cell lines studied, but its presence was not required for P-body formation, and its silencing caused an increase in P-body number. Preliminary mapping suggested that HAX-1 has more than one short P-body-targeting sequence. The pools of P-body-localized HAX-1 and cytosolic HAX-1 were demonstrated to dynamically exchange, suggesting steady flow of the protein. Active transcription was shown to be a factor in the localization of HAX-1 to P-bodies. Also, it was observed that HAX-1 localizes to some unidentified foci, which do not contain DCP1. In addition, it was demonstrated that HAX-1 status influences vimentin expression levels. Overall, HAX-1 was shown to colocalize with P-body markers and influence P-body number per cell in a manner dependent on mRNA availability. Presented data support the hypothesis that HAX-1 is involved in mRNA processing as an element of P-body interaction network.

Abstract
AMP-activated protein kinase (AMPK) is one of the major energy sensor at both: cellular and whole body level. It exists as heterotrimer containing three subunits: the catalytic α subunit, β and regulatory γ. AMPK is localized both in the cytoplasm and in the nucleus. It is activated by increasing concentrations of AMP during the energy shortage, causing activation of catabolic pathways and inhibition of energy consuming processes. AMPK activity can be regulated allosterically: by binding AMP to a regulatory γ subunit, as well as by phosphorylation on Thr172 of the catalytic α subunit by other kinases. Activated AMPK can effectively inhibit the mTOR pathway which is hyperactive in many types of cancer. On the other hand AMPK inactivation associates with the type II diabetes, diet-induced obesity, insulin resistance and the development of other metabolic disorders. The AMPK dysfunction is also observed in inflammation. It was discovered during last years that abnormalities in the AMPK function can induce the metabolic reprogramming in cancer cells known as the Warburg effect. Additionally, AMPK is activated during irradiation. Its activation leads to inhibition of growth. On the other hand, active AMPK enables cells to survive in difficult conditions such as hypoxia, or glucose deprivation. Because of its crucial role in maintaining of the energy homeostasis AMPK is an excellent therapeutic target. However, it still remains unknown what is better: to activate or inhibit the AMPK function.

Abstract
HAX-1 is a multi-functional protein that is involved in the regulation of apoptosis, cell motility and calcium homeostasis. It is also reported to bind RNA: it associates with structural motifs present in the 3' untranslated regions of at least two transcripts, but the functional significance of this binding remains unknown. Although HAX-1 has been detected in various cellular compartments, it is predominantly cytoplasmic. Our detailed localization studies of HAX-1 isoforms revealed partial nuclear localization, the extent of which depends on the protein isoform. Further studies demonstrated that HAX-1 is in fact a nucleocytoplasmic shuttling protein, dependent on the exportin 1 nuclear export receptor. Systematic mutagenesis allowed identification of the two nuclear export signals in the HAX-1 sequence. HAX-1 nuclear accumulation was observed after inhibition of nuclear export by leptomycin B, but also after specific cellular stress. The biological role of HAX-1 nuclear localization and shuttling remains to be established, but the HAX-1 transcript-binding properties suggest that it may be connected to mRNA processing and surveillance. In this study, HAX-1 status was shown to influence mRNA levels of DNA polymerase β, one of the HAX-1 mRNA targets, although this effect becomes pronounced only after specific stress is applied. Moreover, HAX-1 tethering to the reporter transcript caused a significant decrease in its expression. Additionally, the HAX-1 co-localization with P-body markers, reported here, implies a role in mRNA processing. These results suggest that HAX-1 may be involved in the regulation of expression of bound transcripts, possibly as part of the stress response.

Abstract
Aberrant expression of DNA polymerase beta, a key enzyme involved in base excision repair, leads to genetic instability and carcinogenesis. Pol beta expression has been previously shown to be regulated at the level of transcription, but there is also evidence of post-transcriptional regulation, since rat transcripts undergo alternative polyadenylation, and the resulting 3'UTR contain at least one regulatory element. Data presented here indicate that RNA of the short 3'UTR folds to form a strong secondary structure (hairpin). Its regulatory role was established utilizing a luciferase-based reporter system. Further studies led to the identification of a protein factor, which binds to this element-the anti-apoptotic, cytoskeleton-related protein Hax-1. The results of in vitro binding analysis indicate that the formation of the RNA-protein complex is significantly impaired by disruption of the hairpin motif. We demonstrate that Hax-1 binds to Pol beta mRNA exclusively in the form of a dimer. Biochemical analysis revealed the presence of Hax-1 in mitochondria, but also in the nuclear matrix, which, along with its transcript-binding properties, suggests that Hax-1 plays a role in post-transcriptional regulation of expression of Pol beta.
