Article Abstract
Cucumber ( L.) is one of the main vegetable crops in China. The physiological cultivation mechanism and gene function characteristics of cucumber are of great significance to the construction of modern agriculture. Due to the low genetic transformation rate of cucumber, only in situ hybridization, which does not involve the progress of gene modified transformation, is convenient to study mRNA localization, so it is more suitable for determination on mRNA localization in the mature tissue of cucumber. At present, the existing in situ hybridization technology system is more suitable for cucumber meristem than for the mature tissue of cucumber seedlings. Therefore, we optimized the traditional plant in situ hybridization protocol. Taking a known gene CsNPF7.2 (Nitrate Transporter Families protein) as an example, we then optimized the steps of plant tissue culture, gene probe preparation, plant material sampling and fixation, preparation of cross section, hybridization pretreatment, hybridization incubation, chromogenic reaction, microscopy examination, and treatment after reaction termination in order to obtain a new RNA in situ hybridization technique suitable for identification on mRNA localization in mature tissues of cucumber seedlings. This optimized technique will ensure the yield of probes, the integrity of RNA molecules, and the clarity and integrity of plant tissue structure, which is conducive to the study of gene function and screening of key genes in cucumber.

Background And Objectives: Friedreich's Ataxia (FRDA) is a genetic disease that affects a variety of different tissues. The disease is caused by a mutation in the gene ( which is important for the synthesis of iron-sulfur clusters. The primary pathologies of FRDA are loss of motor control and cardiomyopathy.

Synthetic intergeneric amphydiploids and genome-substituted wheat forms are an important source for transferring agronomically valuable genes from wild species into the common wheat (Triticum aestivum L.) genome. They can be used both in academic research and for breeding purposes as an original material for developing wheat-alien addition and substitution lines followed by translocation induction with the aid of irradiation or nonhomologous chromosome pairing.

Galliformes and Anseriformes are two branches of the Galloanserae group, basal to other Neognathae. In contrast to Galliformes, Anseriformes have not been thoroughly researched by cytogenetic methods. This report is focused on representatives of Anseriformes and the evolution of their chromosome sets.

Background: In the DESTINY-B04 trial, patients with pretreated HER2 low metastatic breast cancer (defined as immunohistochemistry score of 1+ or 2+ and negative in situ hybridization) had significant survival improvement with Trastuzumab therapy.
Methods: The goal of our study was to compare the HER2 immunohistochemistry scores of paired primary and metastatic breast cancer, with emphasis on HER2 low criteria and its implications for detailed immunohistochemistry interpretation. Using the pathology database from 2011, we identified 272 cases of primary breast cancers with paired metastases.

Identifying cellular markers within archived formalin-fixed, paraffin-embedded (FFPE) tissues is critical for understanding tissue landscapes impacting animal health, but in situ detection methods are limited in veterinary species by a restricted toolbox of species-compatible immunoreagents. We identify antibodies with conserved in situ reactivity to IBA-1 (macrophages/dendritic cells), CD3ε (T cells), Pax5 (B cells), Ki-67 (cycling cells), and cytokeratin type I/II (epithelial cells) in FFPE tissues of pigs, cattle, and white-tailed deer. Multiplexed brightfield detection (IBA-1/CD3ε/Pax5) in lymph nodes of all three species demonstrated species-specific and species-conserved features of cellular architecture.
