Previous studies on heart growth and development have elucidated important gene- and cellular-level changes. The development of improved biochemical, mathematical, and computational methods has enabled more accurate elaboration of the structural and functional processes of the heart. Systematic analyses of heart complexity have revealed the differences between normal and pathological growth and development in terms of self-organizational ability, energy balance, clock regulation, and heart rate variability. The present study summarizes what is known about cardiac behaviors and characteristics during heart growth and development. The results indicate that the heart demonstrates systematic complexity, and suggest that new characteristic analyses and treatments of heart diseases can be expected in the future.

Castration-resistant prostate cancer (CRPC) remains prostate cancer research and treatment bottleneck. Abnormal androgen receptor (AR) activation still has a pivotal role in CRPC. Multiple mechanisms involve the process, of which overabundant AR-V7 mRNA splicing production is currently focused and increasingly studied. However, factually, there is no definite conclusion about regulation of AR-V7 mRNA splicing. Recently developed knowledge has demonstrated that JMJD6 and U2AF65 as a hopeful approach in mRNA splicing regulation. The authors propose a novel possible mechanism elucidating AR mRNA splicing for CRPC progression using dual-function enzyme JMJD6 and its induced JMJD6/U2AF65/AR-V7 axis. In this hypothesis JMJD6 introduces to AR promoter to demethylate H3R or H4R and promotes AR mRNA transcription via its demethylase activity and interaction with U2AF65. It is expected that JMJD6 could further effectively perform U2AF65 hydroxylation to achieve AR-V7 mRNA splicing via its hydroxylase activity.

Gene sequencing technology has been playing an important role in many aspects, such as life science, disease medicine and health medicine, particularly in the extremely tough process of fighting against 2019-novel coronavirus. Drawing DNA restriction map is a particularly important technology in genetic biology. The simplified partial digestion method (SPDP), a biological method, has been widely used to cut DNA molecules into DNA fragments and obtain the biological information of each fragment. In this work, we propose an algorithm based on 0-1 planning for the location of restriction sites on a DNA molecule, which is able to solve the problem of DNA fragment reconstruction just based on data of fragments' length. Two specific examples are presented in detail. Furthermore, based on 1000 groups of original DNA sequences randomly generated, we define the coincidence rate and unique coincidence rate between the reconstructed DNA sequence and the original DNA sequence, and then analyze separately the effect of the number of fragments and the maximum length of DNA fragments on the coincidence rate and unique coincidence rate as defined. The effectiveness of the algorithm is proved. Besides, based on the existing optimization solution obtained, we simulate and discuss the influence of the error by computation method. It turns out that the error of position of one restriction site does not affect other restriction sites and errors of most restriction sites may lead to the failure of sequence reconstruction. Matlab 7.1 program is used to solve feasible solutions of the location of restriction sites, derive DNA fragment sequence and carry out the statistical analysis and error analysis. This paper focuses on basic computer algorithm implementation of rearrangement and sequencing rather than biochemical technology. The innovative application of the mathematical idea of 0-1 planning to DNA sequence mapping construction, to a certain extent, greatly simplifies the difficulty and complexity of calculation and accelerates the process of 'jigsaw' of DNA fragments.

Prostate cancer (PC) is the most frequently diagnosed cancer and the second leading cause of cancer-related death in men in the Western society. Unfortunately, although the vast majority of patients are initially responsive to androgen-deprivation therapy (ADT), most cases eventually develop from hormone-sensitive prostate cancer (HSPC) to castration-resistant prostate cancer (CRPC). The main reason is PC heterogeneity and evolution during therapy. PC evolution is a continuously progressive process with combination of genomic alterations including canonical AR, TMPRSS2-ERG fusion, SPOP/FOXA1, TP53/RB1/PTEN, BRCA2. Meanwhile, signaling pathways including PI3K, WNT/β-catenin, SRC, IL-6/STAT3 are activated, to promote epithelial mesenchymal transition (EMT), cancer stem cell (CSC)-like features/stemness and neuroendocrine differentiation (NED) of PC. These improve our understanding of the genotype-phenotype relationships. The identification of canonical genetic alterations and signaling pathway activation in PC has shed more insight into genetic background, molecular subtype and disease landscape of PC evolution, resulting in a more flexible role of individual therapies targeting diverse genotype and phenotype presentation.

Prostate cancer (PC) has previously been established as a cold tumor and develops in an inert immunosuppressive environment. Current research focuses on altering the immune microenvironment of PC from cold to hot; thus, in the present review, the diverse roles of estrogen and estrogen receptor (ER) signaling was examined in the tumor cell and tumor immune microenvironment (TIM). We hypothesized that ERα promotes PC progression and ERβ impedes epithelial-mesenchymal transition in PC cells, while in the TIM, ERβ mediates the immunosuppressive environment, and low levels of ERα is associated with disease development. Selective estrogen receptor modulators (SERMs) or selective ER degraders play diverse roles in the regulation of ER isoforms. Patients with PC may benefit from the use of SERMs, including raloxifene, in combination with anti-PD1/PD-L1 checkpoint immunotherapy, or TGF-β or Wnt antagonists. The present review demonstrated that immunotherapy-based strategies combined with SERMs may be an option for the future of PC-targeting therapy.

Selective estrogen receptor modulators contribute to prostate cancer treatment by regulating the tumor immune microenvironment.

Immunotherapies have emerged as potential treatments for metastatic castration-resistant prostate cancer (mCRPC). However, it is still unclear to identify the efficacy and safety of immunotherapy in large-scale samples. We performed a meta-analysis of 7 phase III randomized trials and 3 phase II trials comparing immunotherapy to placebo in mCRPC.

Modulation of histone methylation status is regarded as an important mechanism of epigenetic regulation and has substantial clinical potential for the therapy of diseases, including cancer and other disorders. The present study aimed to provide a comprehensive introduction to the enzymology of histone demethylases, as well as their cancerous roles, molecular mechanisms, therapeutic possibilities, and challenges for targeting them, in order to advance drug design for clinical therapy and highlight new insight into the mechanisms of these enzymes in cancer. A series of clinical trials have been performed to explore potential roles of histone demethylases in several cancer types. Numerous targeted inhibitors associated with immunotherapy, chemotherapy, radiotherapy, and targeted therapy have been used to exert anticancer functions. Future studies should evaluate the dynamic transformation of histone demethylases leading to carcinogenesis and explore individual therapy.
