Matrilysin is a member of the matrix metalloproteinase gene family, which is believed to play an important role in tumor invasion and metastasis. We examined the effects of over- and under-expression of matrilysin on the ability of colon cancer cells to migrate across an artificial membrane in vitro. Introduction of matrilysin caused colon cancer cells to become more invasive as assessed by an in vitro invasion assay. In contrast, expression of matrilysin was down-regulated by all trans-retinoic acid or by introduction of anti-sense matrilysin in BM314 colon cancer cells. This down-regulation caused these cells to become less invasive. We demonstrated a correlation between matrilysin level and the invasive potential of human colon cancer cells, implying an important role for matrilysin in the control of tumor invasion in vitro.

D014162 Transfection The uptake of naked or purified DNA by CELLS, usually meaning the process as it occurs in eukaryotic cells. It is analogous to bacterial transformation (TRANSFORMATION, BACTERIAL) and both are routinely employed in GENE TRANSFER TECHNIQUES. Transfections
D014212 Tretinoin An important regulator of GENE EXPRESSION during growth and development, and in NEOPLASMS. Tretinoin, also known as retinoic acid and derived from maternal VITAMIN A, is essential for normal GROWTH; and EMBRYONIC DEVELOPMENT. An excess of tretinoin can be teratogenic. It is used in the treatment of PSORIASIS; ACNE VULGARIS; and several other SKIN DISEASES. It has also been approved for use in promyelocytic leukemia (LEUKEMIA, PROMYELOCYTIC, ACUTE).

D015536 Down-Regulation A negative regulatory effect on physiological processes at the molecular, cellular, or systemic level. At the molecular level, the major regulatory sites include membrane receptors, genes (GENE EXPRESSION REGULATION), mRNAs (RNA, MESSENGER), and proteins. Receptor Down-Regulation,Down-Regulation (Physiology),Downregulation,Down Regulation,Down-Regulation, Receptor
D016212 Transforming Growth Factor beta A factor synthesized in a wide variety of tissues. It acts synergistically with TGF-alpha in inducing phenotypic transformation and can also act as a negative autocrine growth factor. TGF-beta has a potential role in embryonal development, cellular differentiation, hormone secretion, and immune function. TGF-beta is found mostly as homodimer forms of separate gene products TGF-beta1, TGF-beta2 or TGF-beta3. Heterodimers composed of TGF-beta1 and 2 (TGF-beta1.2) or of TGF-beta2 and 3 (TGF-beta2.3) have been isolated. The TGF-beta proteins are synthesized as precursor proteins.

D016372 RNA, Antisense RNA molecules which hybridize to complementary sequences in either RNA or DNA altering the function of the latter. Endogenous antisense RNAs function as regulators of gene expression by a variety of mechanisms. Synthetic antisense RNAs are used to effect the functioning of specific genes for investigative or therapeutic purposes. Antisense RNA,Anti-Sense RNA,Anti Sense RNA,RNA, Anti-Sense
