Comparison of Two Seminal Detection Methods, The Acid Phosphatase Test and The Zinc Test for Sensitivities in Sexually Assaulted Females Positive of Sperm

Siriraj Medical Journal, 2015
Objective: To determine (1) the duration for which sperm, acid phosphatase, and zinc could be detected; (2) the sensitivities of the acid phosphatase and zinc tests; and (3) the preferred screening tests to provide evidence of sexual assaultin females ...

The mRNA expression and enzymatic activity of three enzymes during embryonic development of the hard tick Haemaphysalis longicornis

Parasites & Vectors, 2019
Background Three main enzymes including cathepsin B, cathepsin D and acid phosphatase are involved in vitellin degradation, which is a major biochemical event of the embryonic development and can provide nutrients and metabolites for tick embryos. In the

The Role of DmCatD, a Cathepsin D-Like Peptidase, and Acid Phosphatase in the Process of Follicular Atresia in Dipetalogaster maxima (Hemiptera: Reduviidae), a Vector of Chagas' Disease. [PDF]

PLoS ONE, 2015
In this work, we have investigated the involvement of DmCatD, a cathepsin D-like peptidase, and acid phosphatase in the process of follicular atresia of Dipetalogaster maxima, a hematophagous insect vector of Chagas' disease. For the studies, fat bodies,

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

The activity of acid phosphatase and the level of storage proteins during the early stages of germination of Lupinus luteus L. and Lupinus angustifolius L. seeds

Acta Societatis Botanicorum Poloniae, 2014
Changes in the level of protein and in the activity of acid phosphatase in seeds of Lupinus luteus L. and Lupinus angustifolius L. during storage and germination were studied. The protein level decreased during germination, mainly as the result of a fall

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

ACID PHOSPHATASE ACTIVITY IN MELANOSOMES OF MELANOCYTES [PDF]

, 1968
A combined cytochemical and electron microscopic demonstration of acid phosphatase activity of melanosomes in melanocytes was carried out on B-16 and Harding-Passey mouse melanoma and the retinal pigment epithelium of white leghorn chick embryos.
