Cellular Protein Trafficking in Low-Temperature Response Pathway
Over the years, although substantial progress has been made in understanding low-temperature response mechanisms in plants, the research is more focused on aerial parts of the plants rather than on the root or whole plant, and more efforts have been made in identifying and testing the major regulators of this pathway preferably in the model organism rather than in crop plants. For the low-temperature stress response mechanism, ICE-CBF regulatory pathway turned out to be the solely established pathway, and historically most of the low-temperature research is focused on this single pathway instead of exploring other alternative regulators.

Basic Principles and Mechanisms of Photodynamic Therapy
Photodynamic therapy (PDT) is a therapeutic modality which uses visible light wavelengths, mainly in the red and near-infrared (NIR) regions, for the activation of photosensitizing molecules (PSs). The widespread diffusion of photodynamic therapy (PDT) as a clinical treatment for solid tumors is mainly limited by the patient’s adverse reaction (skin photosensitivity), insufficient light penetration in deeply seated neoplastic lesions, unfavorable photosensitizers (PSs) biodistribution, and photokilling efficiency due to PS aggregation in biological environments.

Targeting Epigenetic Mechanisms in Multiple Myeloma
Multiple myeloma (MM) is an exceptionally complicated and heterogeneous disease that is caused by the abnormal proliferation of malignant monoclonal plasma cells initiated in the bone marrow. In disease progression, a multistep process including differentiation, proliferation, and invasion is involved.

Intratumoral Heterogeneity and Concept of Cancer Stem Cells
Cancer stem cells (CSCs) present in many tumors are an example of intratumoral heterogeneity of great importance. The original concept of CSCs emerged on the basis of the stem cell theory in its original form and on the reports about the exclusive ability of tumor cells expressing stem cell markers to induce tumor growth.The modern concept of CSCs has been updated by introducing the concept of the cells-of-origin of tumors and according to data obtained by genetic analysis combined with CSC-associated marker profiling and lineage tracing analysis.

Intratumor Heterogeneity in Hepatocellular Carcinoma: Challenges and Opportunities
Hepatocellular carcinoma (HCC) represents a leading cause of cancer-related death, but it remains difficult to treat. Intratumor genetic and phenotypic heterogeneity are inherent properties of breast, skin, lung, prostate, and brain tumors, and intratumor heterogeneity (ITH) helps define prognosis and therapeutic response in these cancers. Several recent studies estimate that ITH is inherent to HCC and attribute the clinical intractability of HCC to this heterogeneity.

Extracellular Vesicles in Hepatocellular Carcinoma
Extracellular vesicles (EVs) are defined as lipid bilayer particles naturally released from cells into the extracellular space. EVs have attracted interest as mediators of intercellular communication following the discovery that EVs contain RNA molecules, including non-coding RNA (ncRNA).Growing evidence for the enrichment of peculiar RNA species in specific EV subtypes has been demonstrated. ncRNAs, transferred from donor cells to recipient cells, confer to EVs the feature to regulate the expression of genes involved in differentiation, proliferation, apoptosis, and other biological processes. These multiple actions require accuracy in the isolation of RNA content from EVs and the methodologies used play a relevant role. In the liver, EVs play a crucial role in regulating cell-cell communications and several pathophysiological events in the heterogeneous liver class of cells via horizontal transfer of their cargo.

FAK Inhibition and Corneal Fibroblast Differentiation in vitro
Fibrosis is often known as a response of a tissue to injury, and since the three transforming growth factor-beta (TGF-β) isoforms (TGF-β1, -β2, and -β3) are the main regulators of cell migration, differentiation, proliferation, and gene expression, they were implicated in both reparative and fibrotic responses. All three TGF-β isoforms are homologues, sharing an extensive similarity in their amino acid sequences (80%), which may result in overlapping functions (i.e., SMAD-dependent signaling, modulating inflammatory responses); however, subtle differences in the sequences exist, thus potentially eliciting opposing effects. For example, several studies showed that TGF-β1 and -β2 are factors that drive the formation of fibrosis in corneal scarring models [8,9,10], whereas TGF-β3 was reported to downregulate fibrosis and promote scarless wound healing (healing without fibrosis).

Structure and Function of Peroxiredoxin IV
Peroxiredoxin IV (Prx4) is a 2-Cysteine peroxidase with ubiquitous expression in human tissues. Prx4 scavenges hydrogen peroxide and participates in oxidative protein folding in the endoplasmic reticulum. In addition, Prx4 is secreted outside the cell. Prx4 is upregulated in several cancers and is a potential therapeutic target. Here, the resarchers have summarized the structure and function of Prx4. Oxidative stress is known to activate pro-inflammatory pathways. Chronic inflammation is a risk factor for cancer development. Hence, redox enzymes such as Prx4 are important players in the crosstalk between inflammation and cancer. Understanding molecular mechanisms of regulation of Prx4 expression and associated signaling pathways in normal physiological and disease conditions should reveal new therapeutic strategies. Although Prx4 is a promising therapeutic target for inflammatory diseases and cancer, further research needs to be conducted to bridge the gap to clinical application.

Applications for Colon Organoid Models in Cancer
Organoids are 3D organ-like structures grown from stem cells in vitro that mimic the organ or disease from which they are derived. Due to their stem cell origin, organoids contain a heterogeneous population of cells reflecting the diversity of cell types seen in vivo. Similarly, tumour organoids reflect intratumoural heterogeneity in a way that traditional 2D cell culture and cell lines do not, and, therefore, they show greater promise as a more relevant model for effective disease modelling and drug testing. Tumour organoids arise from cancer stem cells, which contribute to many of the greatest challenges to cancer treatment, including therapy resistance, tumour recurrence, and metastasis. Organoids show promise as relevant in vitro models with a range of applications from drug testing to modelling disease progression.

Survivin Small Molecules Inhibitors
Survivin, as a member of the inhibitor of apoptosis proteins (IAPs) family, acts as a suppressor of apoptosis and plays a central role in cell division. Survivin has been considered as an important cancer drug target because it is highly expressed in many types of human cancers, while it is effectively absent from terminally differentiated normal tissues. Moreover, survivin is involved in tumor cell resistance to chemotherapy and radiation.
