Bera RK, Rana S, Bhattacharya S. Interaction intensity in strategic fitness: A quantifying yardstick of selection optimization for evolutionary game. Math Biosci 2024; 375:109241.

Abstract
The notion of the fitness of a strategy has been assimilated as the reproductive success in the evolutionary game. Initially, this fitness was tied to the game's pay-off and the strategy's relative frequency. However, density dependence becomes exigent in order to make ecologically reliable fitness. However, the contributions of each different type of interaction to the species's overall growth process were surprisingly under-explored. This oversight has occasionally led to either more or less prediction of strategy selection compared to the actual possibility. Moreover, density regulation of the population has always been analysed in a general way compared to strategy selection. In this context, our study introduces the concept of mean relative death payoff, which helps in assessing interaction intensity coefficients and integrates them into strategic fitness. Based on this fitness function, we develop the frequency-density replicator dynamics, which eventually provides distinguishing criteria for directional and balancing selection. Our optimized, evolutionarily stable strategy emerges as a superior alternative to the conventional trade-off between selection forces and ecological processes. More significantly, mean relative death pay-off has both conditional and quantitative roles in getting a stable population size. As a case study, we have extensively analysed the evolution of aggression using the Hawk-Dove game. We have shown that pure Dove selection is always beneficial for species growth rather than pure Hawk selection, and the condition of selection is dependent on external mortality pressure. However, the condition of coexistence is independent of external mortality pressure, representing a strong evolutionary selection that optimizes population density governed by interaction intensity.

Dühring S, Schuster S. Studying mixed-species biofilms of Candida albicans and Staphylococcus aureus using evolutionary game theory. PLoS One 2024; 19:e0297307.

Abstract
Mixed-species biofilms of Candida albicans and Staphylococcus aureus pose a significant clinical challenge due to their resistance to the human immune system and antimicrobial therapy. Using evolutionary game theory and nonlinear dynamics, we analyse the complex interactions between these organisms to understand their coexistence in the human host. We determine the Nash equilibria and evolutionary stable strategies of the game between C. albicans and S. aureus and point out different states of the mixed-species biofilm. Using replicator equations we study the fungal-bacterial interactions on a population level. Our focus is on the influence of available nutrients and the quorum sensing molecule farnesol, including the potential therapeutic use of artificially added farnesol. We also investigate the impact of the suggested scavenging of C. albicans hyphae by S. aureus. Contrary to common assumptions, we confirm the hypothesis that under certain conditions, mixed-species biofilms are not universally beneficial. Instead, different Nash equilibria occur depending on encountered conditions (i.e. varying farnesol levels, either produced by C. albicans or artificially added), including antagonism. We further show that the suggested scavenging of C. albicans' hyphae by S. aureus does not influence the overall outcome of the game. Moreover, artificially added farnesol strongly affects the dynamics of the game, although its use as a medical adjuvant (add-on medication) may pose challenges.

Abstract
Prostate cancer (PC) is one of the most common cancers in males and the fifth leading reason of death. Age, ethnicity, family history, and genetic defects are major factors that determine the aggressiveness and lethality of PC. The African population is at the highest risk of developing high-grade PC. It can be challenging to distinguish between low-risk and high-risk patients due to the slow progression of PC. Prostate-specific antigen (PSA) is a revolutionary discovery for the identification of PC. However, it has led to an increase in over diagnosis and over treatment of PC in the past few decades. Even if modifications are made to the standard PSA testing, the specificity has not been found to be significant. Our understanding of PC genetics and proteomics has improved due to advances in different fields. New serum, urine, and tissue biomarkers, such as PC antigen 3 (PCA3), have led to various new diagnostic tests, such as the prostate health index, 4K score, and PCA3. These tests significantly reduce the number of unnecessary and repeat biopsies performed. Chemotherapy, radiotherapy, and prostatectomy are standard treatment options. However, newer novel hormone therapy drugs with a better response have been identified. Androgen deprivation and hormonal therapy are evolving as new and better options for managing hormone-sensitive and castration-resistant PC. This review aimed to highlight and discuss epidemiology, various risk factors, and developments in PC diagnosis and treatment regimens.

Evolutionary Analysis of TCGA Data Using Over- and Under- Mutated Genes Identify Key Molecular Pathways and Cellular Functions in Lung Cancer Subtypes. Cancers (Basel) 2022; 15:18. [PMID: 36612014 PMCID: PMC9817988 DOI: 10.3390/cancers15010018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 11/30/2022] [Accepted: 12/08/2022] [Indexed: 12/24/2022] Open
Abstract
We identify critical conserved and mutated genes through a theoretical model linking a gene’s fitness contribution to its observed mutational frequency in a clinical cohort. “Passenger” gene mutations do not alter fitness and have mutational frequencies determined by gene size and the mutation rate. Driver mutations, which increase fitness (and proliferation), are observed more frequently than expected. Non-synonymous mutations in essential genes reduce fitness and are eliminated by natural selection resulting in lower prevalence than expected. We apply this “evolutionary triage” principle to TCGA data from EGFR-mutant, KRAS-mutant, and NEK (non-EGFR/KRAS) lung adenocarcinomas. We find frequent overlap of evolutionarily selected non-synonymous gene mutations among the subtypes suggesting enrichment for adaptations to common local tissue selection forces. Overlap of conserved genes in the LUAD subtypes is rare suggesting negative evolutionary selection is strongly dependent on initiating mutational events during carcinogenesis. Highly expressed genes are more likely to be conserved and significant changes in expression (>20% increased/decreased) are common in genes with evolutionarily selected mutations but not in conserved genes. EGFR-mut cancers have fewer average mutations (89) than KRAS-mut (228) and NEK (313). Subtype-specific variation in conserved and mutated genes identify critical molecular components in cell signaling, extracellular matrix remodeling, and membrane transporters. These findings demonstrate subtype-specific patterns of co-adaptations between the defining driver mutation and somatically conserved genes as well as novel insights into epigenetic versus genetic contributions to cancer evolution.

Abstract
With the rapid development of social economy, the deterioration of environment has become more and more serious; it is urgent to find a balance between economic development and environmental protection. Therefore, enterprises are appealed to invest in environmental protection, and local municipalities are appealed to supervise the environmental behaviors of enterprises, while central government plays a role of regulation. In order to study the preconditions for a better environmental strategy combination of local municipalities and enterprises, an evolutionary game theory was first constructed in this paper, then the evolutionary stable strategy (ESS) of local municipalities and enterprises under different scenarios was examined, and finally a simulation was used to test the results of the analysis. The results indicate that central government's regulation has influence on the strategies chosen by local municipalities and enterprises, the larger the degree of central government's incentives are, the more possible local municipalities and enterprises would choose environment-friendly strategies; and the intensity of central government's regulation, the cost and benefits of local municipalities' supervision, and the cost and benefits of enterprises' environmental investment are the key influence factors.

Abstract
Prostate cancer is one of the predominant cancers affecting men and has been widely reported. In the past, various therapies and drugs have been proposed to treat prostate cancer. Among these treatments, gene therapy has been considered to be an optimal and widely applicable treatment. Furthermore, due to the increased specificity of gene sequence complementation, the targeted delivery of complementary gene sequences may represent a useful treatment in certain instances. Various gene therapies, including tumor-suppressor gene therapy, suicide gene therapy, immunomodulation gene therapy and anti-oncogene therapies, have been established to treat a wide range of diseases, such as cardiac disease, cystic fibrosis, HIV/AIDS, diabetes, hemophilia, and cancers. To this end, several gene therapy clinical trials at various phases are underway. This overview describes the developments and progress in gene therapy, with a special focus being placed on prostate cancer.

Abstract
Gastric cancer (GC) is one of the most common malignant tumors in China and the third leading cause of cancer-related death. Parkin has been shown to be a tumor suppressor in a variety of malignancies, including GC. However, the mechanism of Parkin in GC remains unclear. In this study, the low expression of Parkin in GC cells and patient tumor tissues was observed, and Parkin inhibited proliferation and migration of GC cells. Additionally, doxorubicin (DOX) upregulated the expression of Parkin and promoted its anticancer effect. Forkhead box O3 (FOXO3a) is a crucial transcription factor that involves in the regulation of cancer cell proliferation, apoptosis, and metabolism. Here, we found that FOXO3a inhibits cell proliferation, migration, and promotes apoptosis in GC by regulating Parkin expression at the transcriptional level. In addition, Parkin inhibited cell proliferation, migration, and promoted apoptosis by inhibiting ATP-binding box protein E1 (ABCE1) expression. In summary, our results demonstrated a new regulatory axis of FOXO3a-Parkin-ABCE1 that modulated GC cell proliferation, migration, and apoptosis, and it can serve as a potential therapeutic target in GC.

Abstract
Monoclonal antibodies (mAbs) have always provided outstanding therapeutic arsenal in the
treatment of cancer, be it hematological malignancies or solid tumors. Monoclonal antibodies mediated
targeting of cancer genes in general and tumor-suppressor genes, in particular, have appreciably allowed
the possibilities of trafficking these antibodies to specific tumor mechanisms and aim for the pin-point
maneuvered tumor treatment strategies. The conventional cancer treatment options are associated with
enormous limitations like drug resistance, acute and pan-toxic side effects and collateral damage to other
unrelated cells and organs. Therefore, monoclonal antibody-mediated treatments have some special advantages
of specific targeting of cancer-related genes and minimizing the off-target side effects. A large
number of monoclonal antibody-mediated treatment regimen viz. use of immunoconjugates, clinically
targeting TGFβ with pan-TGFβ monoclonal antibodies, p53 by its monoclonal antibodies and EGFRtargeted
monoclonal antibodies, etc. have been observed in the recent past. In this review, the authors
have discussed some of the significant advances in the context of targeting tumor suppressor genes with
monoclonal antibodies. Approximately 250 articles were scanned from research databases like PubMed
central, Europe PubMed Central and google scholar up to the date of inception, and relevant reports on
monoclonal antibody-mediated targeting of cancer genes were selected. mAb mediated targeting of tumor
suppressor genes is a recent grey paradigm, which has not been explored up to its maximum potential.
Therefore, this review will be of appreciable significance that it will boost further in-depth understanding
of various aspects of mAb arbitrated cancer targeting and will warrant and promote further rigorous
research initiatives in this regard. The authors expect that this review will acquaint the readers
with the current status regarding the recent progress in the domain of mAbs and their employability and
targetability towards tumor suppressor genes in anti-cancer therapeutics.

Abstract
BACKGROUND The global morbidity of cancer is rising rapidly. Despite advances in molecular biology, immunology, and cytotoxic and immune-anticancer therapies, cancer remains a major cause of death worldwide. Protein tyrosine phosphatase non-receptor type 12 (PTPN12) is a new member of the cytoplasmic protein tyrosine phosphatase family, isolated from a cDNA library of adult colon tissue. Thus far, no studies have reviewed the correlation between PTPN12 gene expression and human tumors. METHODS This article summarizes the latest domestic and international research developments on how the expression of PTPN12 relates to human tumors. The extensive search in Web of Science and PubMed with the keywords including PTPN12, tumor, renal cell carcinoma, proto-oncogenes, tumor suppressor genes was undertaken. RESULTS More and more studies have shown that a tumor is essentially a genetic disease, arising from a broken antagonistic function between proto-oncogenes and tumor suppressor genes. When their antagonistic effect is out of balance, it may cause uncontrolled growth of cells and lead to the occurrence of tumors. PTPN12 is a tumor suppressor gene, so inhibiting its activity will lead directly or indirectly to the occurrence of tumors. CONCLUSION The etiology, prevention, and treatment of tumors have become the focus of research around the world. PTPN12 is a tumor suppressor gene. In the future, PTPN12 might serve as a novel molecular marker to benefit patients, and even the development of tumor suppressor gene activation agents can form a practical research direction.
